(Turmeric) Leaf Extract and Its Potential Application in Consumer Goods <p>Turmeric has been used as a functional food material but, other parts of the plant such as leaves are wasted as byproducts. This project aims at utilization of turmeric leaves which is generally thrown off or burnt as waste. Disposal of turmeric leaves after harvest of turmeric possesses a huge challenge for the farmers, removal of leaves from the plant comes with an extra cost as the workers need to be paid for removing the leaves, thus to cut the cost farmers burn the leaves. India dominates the world production scenario contributing 80% of turmeric growth, which is mainly used as spice with other applications being used in preparation of dyes, drugs, cosmetics and for religious ceremonies. Karnataka is the third largest producer of turmeric in India. According to studies, the phytochemical characteristics of the turmeric leaf extract demonstrates functional effects such as cosmeceutical, skin immunity, anti-inflammation, antimicrobial, anti-insecticidal activities and antixidant activities. Turmeric leaves also have large volume and surface area and thus can be used for industrial applications. Turmeric leaf oil is rich in phenolic components. The main constituents of the turmeric leaves are curcumnene, limonene, phellandrene and turmerone. In this regard, this project aims at complete utilization of turmeric leaves and turning the leaves which is generally regarded as waste into value added products. The final products developed from the leaves are Dhoop sticks and Room Freshener. The Dhoop sticks developed are organic and chemical free and has aroma that can be refreshing and relaxing as turmeric leaves have strong aroma. Turmeric leaves are rich in Curcumin which is known to have Anti-insecticidal properties in this regard Dhoop sticks are being developed. Perfumes/Room freshener are developed using turmeric leaves as they have anti-bacterial properties and prevents any type of skin allergy while producing fresh fragrance. The products are developed keeping in the mind the source of extra income they act as for the farmers. When tested for anti-bacterial activity the results gave positive results, which is an indication that turmeric leaves have great applications and needs to be explored.</p> Hariharan P. Prashant S.

Moench) <p>The present study on general combining ability effects and specific combining ability effects involves seven parents <em>viz.,</em> G1 (Arka Anamika), G2 (Aruna), G3 (Varsha Uphar), G4 (Pusa-5), G5 (MDU-1), G6 (Kashi Kranti), G7 (Ankur-41) with their 21 F<sub>1</sub> hybrids through half-diallel mating system. The present investigation was undertaken using Randomized Block Design with three replications. The combining ability effects were estimated for seven characters <em>viz.,</em> days to first flowering, days to first fruit harvest, fruit length, fruit girth, fruit weight, number of immature seeds per fruit and fruit yield per plant. The results showed that <em>gca </em>effects of parents and <em>sca</em> effect of hybrids were significantly differed. The SCA variance was higher than the GCA variance that indicates the presence of preponderance of non-additive gene action for all the seven traits <em>i.e., </em>presence of preponderance of non-additive gene action for all characters except number of nodes per plant. Among the parents, G3 was found to be a good general combiner based on the <em>per se </em>performance and <em>gca </em>effects for its flowering and yield traits. Among the 21 F<sub>1</sub> hybrids, the crosses G3 x G5 and G4 x G6 were superior on the basis of <em>per se </em>performance and <em>sca</em> effect for flowering and yield attributes. Hence, these hybrids were used for further exploitation of heterosis.</p> D. Gokilappriya S. Anuja R. Kandasamy T. Sabesan Copyright (c) 2023 © Copyright I.K. Press.

Genotypes <p>Pigeonpea [<em>Cajanus cajan </em>(L.) Millsp.] is an important deep-rooted pulse crop, predominantly cultivated in rainfed areas by small and marginal farmers in India and South Africa. The crop’s productivity is severely constrained due to abiotic and biotic stresses in its agro-ecosystem. Molecular variability assessment in pigeonpea can be the key for successful breeding to mitigate the crop from future biotic and abiotic stresses. Molecular markers based genetic diversity analysis was done to evaluate locally collected 32 genotypes of pigeonpea. Total 20 microsatellite markers were used in the present analysis. Pigeonpea genotypes had higher level of genetic diversity. Microsatellite markers were able to discriminate the studied genotypes into three clusters. Most of the genotypes were grouped together according to their collection sites. The findings of the present study open the window of opportunity,&nbsp; for future research and exploitation of these locally collected genotypes for pigeonpea crop improvement.</p> Niraj Tripathi Dhaneshwar B.

Iron nanoparticles (Fe NPs) are one of the main sources of plant nutrition because they are effective in releasing a variety of pH values. To study the effect of different concentrations of Fe NPs (0, 0.5, 1.0, 2.0, 4.0 ml/l) on the regeneration and rooting of Bartamoda cv. date palm, as well as to ascertain the content of carbohydrates and chlorophyll in shoots, an experiment was conducted at the Central Laboratory for Research and Development of Date Palm, Agricultural Research Center Giza, Egypt. Adding treatments of Fe NPs at 1.0 and 2.0 ml/l to MS medium containing BA at 2.0 mg/l and NAA at 0.5 mg/l significantly enhanced growth (number of shoots/cluster, number of leaves/cluster, and leaf length), according to Results. MS medium supplemented with NAA at 1.0 mg/l and Fe NPs at 1.0 ml/l showed the highest rooting percentage (89.0%). Treating the shoots with varying doses of iron nanoparticles led to a significantly higher iron content compared to the untreated control shoots. The carbohydrate content improved steadily and significantly with increasing Fe NP concentration. Compared with the control group, treatments with Fe NPs at 1.0 and 2.0 ml/l enhanced the levels of chlorophyll a, chlorophyll b, and carotenoids.</p> <p>Through the use of random amplified polymorphic DNA (RAPD) profiles, the somaclonal variation in shoots that can be caused by Fe NPs during the multiplication stage was examined. To amplify DNA from various shoots, seven random 10-mer primers were applied. The shoots' RAPD patterns matched those of the original plant mother, proving that Fe NPs did not cause somaclonal variation that could be seen using the RAPD method.</p> Rasha N. Arafa Sayed A. A.

This technique also ensures precision in production schedules and product quality, regarding plant homogeneity and vigour. Nevertheless, the occurrence of contamination in an <em>in vitro </em>culture is frequent, and might result in high damage. Plant materials have different kind of microbes i.e., exogenous and endogenous in nature which is the main reason for contamination in tissue culture. Pre-treatments to explants with fungicides and bactericides can be effectively used to eliminate the surface contamination. Surface sterilizing agents, their levels and duration of exposure are known to impact the <em>in vitro </em>culture establishment. In the present experiment, pre-treatment of explants was carried out with Teepol Bleach<sup>TM</sup> solution (0.1%) and Bavistin<sup>TM</sup> (0.1%) for 15 and 20 minutes respectively for effective control of fungal contaminations in all the cultures. For the control of bacterial contamination antibiotics were added in culture medium. Surface sterilization of explants with 0.1% mercuric chloride (HgCl<sub>2</sub>) for five minutes gave the maximum survival of the growing cultures.</p> Satish Kumar S. K.

Res. Inst., A.R.C., Giza Egypt, a pot experiment was conducted during 2021 seasons to study the response of Taiwan sugar palm (<em>Arenga engleri</em> Bcc.) seedlings to planting in the different growing media (sand, clay and sand + clay at 1: 1, v/v), different irrigation treatments (100, 75 and 50 % of F.C. of each medium) and their interactions in a factorial experiment arranged in completely randomized design with three replications.</p> <p>Results of the experiment have shown that planting in sand + clay mixture (1:1, v/v) gave the highest mean values of different growth parameters, with few exceptions as compared to planting either in sand alone or clay standalone in the two seasons. In addition, the gradual decrement in water supply was accompanied by a gradual decrease in values of all vegetative and root growth traits to reach minimum by 50 % of F.C. water treatment in both seasons. However, the reduction percentage caused by 75 % of F.C. treatment ranged between 1.1 to 17.6 % for different growth characters, while that induced by 50 % of F.C. one ranged between 23.8 to 40.4 %. The growth performance of plants watered with 75 % F.C. was greatly resemble to that of plants watered with 100 % F.C., whereas that of plants watered with 50 % F.C. was not, as it gave the smallest plants, which can be used for decorating the limited area places. The treatments showed a marked influence on various growth traits, but the dominance was for the combining between planting in sand + clay mixture and irrigating with 100 % F.C. water treatment, as such combination recorded the utmost high means in different growth traits over the other combinations, with few exceptions in both seasons. A similar response occurred, concentrations of chlorophyll a, b, carotenoids, total carbohydrates, N, P and K in the leaves.</p> <p>Accordingly, it can be recommended to planting arenga sugar palm seedlings in sand + clay mixture at equal volumetric parts and irrigating them with 100 %, 75 % or 50 % of F.C. water treatments to produce different sizes from such ornamental palm as pot plants suitable for landscaping the limited places of different areas.</p> Sayed M.

There is one of the obstacle arises in growing this plant by farmers in India is the lack of planting materials. The young plants of <em>A. digitata </em>L. have to be imported form selected nurseries. Therefore, micropropagation can be used as a substitute method to create offspring that are genetically similar to the parent plant. In order to micropropagate Kalpvriksh (<em>A. digitata </em>L.), this experiment is being conducted utilizing shoot tip explants. For shoot proliferation, these explants are grown in MS medium containing various concentrations of BAP (6- Benzylamino purine): 0.5, 1.0, 1.5, 2.5, 5.0 mg/L. Shoots are rooted in a medium containing at the same concentration of NAA (α-Napthalene Acetic Acid) 0.5 mg/L alone or with combination. Complete Randomized Design (CRD) is used to conduct each experiment. ANOVA and the Duncan New Multiple Range test are used to examine the data. According to the technique for micropropagation of <em>A. digitata</em> L. The concentration of BAP and NAA was found to be 1.5 mg/L and 0.5 mg/L respectively which showed better enhancement for shoot regeneration and rooting for micropropagation of Kalpvriksha (<em>Adansonia digitata</em> L.) tree. </p> Mujeeb Ur.

This technology involves the synthesis of nanoparticles with controllable size, shape, and material dispersion at nanometer-scale lengths. In the current work, copper nanoparticles have been synthesized by simple green technology using <em>Persea americana</em> leaf extract. The formation of Cu NPs was monitored by recording UV-Vis absorption spectra showing surface plasmon resonance at 320 nm. The green synthetic copper nanoparticles will be further characterized by FT-IR, FESEM, EDS and XRD. FT-IR identified the presence of active groups and phenolic groups. The crystal morphology and size of the nanoparticles will be determined by FESEM and X-ray diffraction studies. It was found that the average particle size of the copper nanoparticles was in the range of 71 nm. These biosynthetic copper nanoparticles were tested for the photocatalytic dye degradation of commercially important textile dyes such as methylene blue The antioxidant activity of green synthesized nanoparticles from the fruit extract was analysed by DPPH-free radical scavenging assay method. The results show that green synthetic nanoparticles have strong dye degradation potential.</p> S. Selvakumar E. Abirami K. K. Prapanjan Copyright (c) 2023 © Copyright International Knowledge Press.

Evaluation of genetic diversity is a vivacious component of mustard breeding programmes for efficient utilization of plant genetic resources. In present study, 77 microsatellite markers were employed to assess the genetic diversity of 75 Indian mustard genotypes. Results revealed positive amplification for all SSRs, with 21 SSRs exhibiting polymorphic amplicons. A total of 99 alleles, ranging from 3 to 5 with an average of 4.71 alleles per SSR marker were obtained. The major allele frequency varied between 0.26 (cnu/m616) and 0.56 (ENA28F) with an average value of 0.36. The average polymorphic information content (PIC) value was 0.67 and ranged between 0.43 (ENA28F) and 0.76 (gi258660710gbGT071338.1). Mean value of 0.72 was detected for each pair of SSR primers, with the gene diversity per locus ranging between 0.53 (ENA28F) and 0.79 (gi258660710gbGT071338.1). The dendrogram grouped the 75 genotypes into three main clusters or subpopulations based on Unweighted Neighbour-Joining technique. The study revealed better understanding of the genetic diversity among different Indian mustard genotypes using genomic-SSR markers that could be exploited for the genetic improvement of the crop.</p> Aditi Shrivastav Manoj Kumar Tripathi Sushma Tiwari Niraj Tripathi Prakash N.

If there is no population variation, there cannot be a breeding programme. Breeders need a lot of labour and money to screen germplasm for a desired gene. Additionally, these screenings are compliant with environmental effects. The method of "allele mining" is employed to identify suitable alleles of a candidate gene affecting important agronomic properties or naturally occurring allelic variations. TILLING and Eco-TILLING are the ideal solutions to this issue for allele mining. A technique known as "tilling" uses mutagens to introduce new diversity in a specific allele. Then, different sequencers are used to screen the diversity in a gene to identify different mutations. The best mutant among them can then be directly used in breeding programmes. In a modified version, alleles of a gene that are present in the population are identified by screening natural populations. Eco-TILLING is the name of this fresh iteration of the technology. The generation of novel haplotypes, the use of molecular markers to characterize genetic diversity and the syntenic links across crop genotypes, as well as marker-assisted selection are just a few of the many applications of allele mining in agriculture and crop improvement. Many genes may be found and used in the breeding of many crop species using these reverse genetics techniques.<em>Allele mining</em></p> Shivangi Tare Sushma Tiwari Madhurjit Singh Rathore M.

Groundnut seeds sown in pot soil mixed with the inoculum of <em>A.niger </em>at 5% level alone served as control. The treatments were given as per the schedule and foliar spray was given at 20% DAS. The experiment was conducted with three replications in a completely randomized design. All observations <em>viz</em>., the collar rot disease incidence (PDI- at 30 DAS), plant height (cm), plant biomass and pod yield was assessed and recorded at harvest following standard procedures. The results showed that all the treatments significantly reduced the collar rot disease incidence compared to the control. Among the treatments, seed treatment plus foliar spray of Pyraclostrobin 20% WDG at 0.15 % (T3) recorded significantly the least collar rot incidence of 14.12 per cent, maximum germination per cent (93.28%) and maximum yield (132.23 g/pot) than other treatments. The dosage level with Pyraclostrobin 20% WDG as seed treatment @ 1.0 g/kg of seed plus foliar spray at the conc. of 0.1% recorded statistically on par results with T3 the best treatment</p> S.

Because antidiabetic traditional drugs are expensive, have side effects, and are ineffective, researchers are looking into novel medicinal plants to find a long-term cure that is inexpensive, has few or no side effects, and is highly effective in treating diabetes and its consequences. <em>Detarium senegalense</em> is a versatile plant used to cure a variety of ailments, including diabetes. This research aimed to investigate the ameliorative potentials of methanol bark extract of <em>Detarium senegalense</em> in streptozotocin-Induced Diabetic male Wistar Rats. Thirty (30) adult male Wistar rats weighing 120-180gm were chosen at random and put into six (6) groups of five rats each (n=5) for this investigation. A single intraperitoneal injection of streptozotocin (150mg/kg) produced diabetes in rats. Normal and diabetic control groups are represented by groups 1 and 2, respectively. Group 3, a diabetic group, received metformin (50mg/kg). Groups 4, 5, and 6 received methanol bark extract of <em>Deterium senegalenses</em> at 250, 500, and 1000 mg/kg/day, respectively. The animals were euthanized at the end of the 21-day treatment period, and organs were excised for biochemical examination. The generated data was analyzed with the SPSS software, and the results were expressed as mean SEM. Result confirms <em>Detarium senegalense</em> methanol bark extract as a hypoglycemic agent on the diabetic rats, by decreasing blood glucose level and the activity of metabolic enzymes (α-amylase and α-glucosidase), increase hexokinase, Superoxide dismutase, Catalase, Glut 1 and Glut 2 activities while decreasing the activities of <em>Malondialdehyde</em>. Conclusively, the bark of <em>Detarium senegalense</em> has been shown to have anti-diabetic and anti-oxidative.</p> Odeghe Hope Enameguonor Ojieh Anthony Emeka Ossai Nduka Richard Enaohwo Taniyohwo Mamerhi Copyright (c) 2023 © Copyright International Knowledge Press.

A survey was conducted in and around Jalandhar region of Punjab, India to study viral symptoms in the bitter gourd fields. The plants showed reduced fruit size, upward leaf curling and mosaic symptoms, indicating begomovirus infection. DNA was isolated from the symptomatic leaves and tested for begomovirus infection using group-specific PCR primers. Amplified products were cloned into pMD20-T vector and sequenced. Based on the obtained sequence, new sets of primers were designed and used for amplification of complete DNA-A and DNA-B. Complete DNA-A and DNA-B were cloned in pMD20-T and sequenced. Sequence analysis of the present DNA-A and DNA-B showed their highest identity with <em>Tomato leaf curl New Delhi virus </em>(ToLCNDV). The associated <em>Tomato leaf curl New Delhi alphasatellite </em>was amplified using universal primers, cloned and sequenced. In phylogenetic analysis, the present DNA-A and DNA-B grouped with ToLCNDV isolates and other begomoviruses reported from bitter gourd. Phylogenetic analysis of the present alphasatellite showed its closet identity with <em>Tomato leaf curl New Delhi alphasatellite</em>. Recombination analysis of the DNA-A sequence showed that the present bitter gourd isolate might be a recombinant of <em>Squash leaf curl China virus</em> (SLCChV) as a major parent and <em>Chilli leaf curl virus</em> as a minor parent. Analysis of the DNA-B suggested it to be a recombinant of SLCChV as a major parent and <em>Chyaote enation yellow mosaic virus </em>as a minor parent. The present alphasatellite might be a recombinant of <em>Tomato yellow spot alphasatellite</em> as a major parent and <em>Croton yellow mosaic alphasatellite </em>as a minor parent. The percent identities of the nucleotide and amino acid sequences validate and support the results of the phylogenetic and recombination analyses.</p> Priya Lager Jyoti Sharma Yogesh Kumar Copyright (c) 2023 © Copyright International Knowledge Press.

Bean seedlings were grown in plastic pots containing acid washed sand for 10 days and watered daily with ½ Strength Hoagland’s Solution containing 5 mM NH<sub>4</sub>NO<sub>3</sub> as nitrogen source and desired concentration of ZnCl<sub>2</sub>. Zn supply increased seedling weight and shoot length at 0.001 mM whereas root length decreased at all concentrations.</p> <p>Amongst the antioxidative enzymes, super oxide dismutase (SOD) activity increased up to 0.1 mM significantly and then decreased at 1 mM in leaf tissue whereas in root tissue it decreased at 0.001 mM and then increased significantly. The catalase (CAT) activity increased at all the concentration being more prominent at 0.1 mM in leaf whereas in roots it increased substantially at 0.1 and 1 mM Zn. Ascorbate peroxidase (APX) activity in leaf increased at 0.1 mM but decreased at 0.001 and 1 mM, whereas in roots it decreased at all the concentration. Various <em>in vitro</em> activities of NR were analysed in response to Zn supply. The effect of Zn on NADH-NR is more substantial than MVH-NR at all the concentrations. Also NR<sub>max</sub> and NR<sub>act</sub> increased at all the concentration of Zn being most prominent at 0.1 mM in leaf and at 1 mM in root tissue.</p> Shaishavee Saini Rekha Gadre Copyright (c) 2023 © Copyright International Knowledge Press.

Extract in Alloxan Induced Diabetes in Wistar Albino Rats <p>In this present scenario,medicinal plants are becoming popular for the treatment of various diseases all over the world. Some of them are being traditionally used in diabetes for human welfare. Diabetes is a common endocrine disorder that impairs glucose metabolism resulting in severe diabetic complications including retinopathy, angiopathy, nephropathy, neuropathy and causing neurological disorder due to perturbation in utilization of glucose. In the present study, an effort has been made to assess the antidiabetic properties of <em>Ficus glomerata </em>leaf extract treatment in alloxan monohydrate induced diabetic albino rats. Present study refers to the medicinal plant <em>Ficus glomerata l</em>eaf metabolites compared to insulin treatment animal model. Diabetes was induced in albino rats with the help of alloxan monohydrate (150 mg/kg) intraperitoneal saline injection. Present study was carried out to evaluate the anti-diabetic activity of <em>Ficus glomerata </em>aqueous leaf extract in diabetic albino rats for 4 week treatment. The treatment with aqueous leaf extract at high dose (1g/kg) significantly decreased circulating blood glucose concentration in comparison to mild dose (500mg/kg) and low dose (100mg/kg) respectively in diabetic rats. The aqueous leaf extract also improved the hematological picture, weight, biochemical profile and glucose intolerance lowering effects in diabetic animal models. In conclusion, <em>Ficus glomerata </em>leaf metabolites have tremendous antidiabetic potential in alloxan-induced experimental models. The results suggest the possibility that <em>Ficus glomerata </em>leaves metabolites to cure diabetes in herbal medicine.</p> Sanjeev Kumar N. K. Prasad Arti Kumari Kumari Shachi N. K.
