Abstract
An experiment was conducted in the greenhouse of the Department of Biology / College of Science / University Mosul, which included the cultivation of Lupinus albus L in clay mix soil Mud, with plants exposed to three levels of field capacity (35, 55, and 75%). As well as treating plants with three concentrations of growth regulator Indole Butyric acid IBA which is (0.0, 25, 50) mg / L, To see the effect of those factors on growth and some Physiological traits of Lupine. The results of greenhouse experiment were analyzed by using a completely randomized design (.C.R.D) as a factorial experiment, The results showed that the plants treated with IBA growth regulator were superior in all traits Studied plant height, shoot dry weight, Root dry weight, leaves number / plant, relative water content at (18.4,14.3, 36.5 and 37.5%) respectively compared to plants without treatment, as noted there was a significant decrease in the above traits when the humidity decreased from 75 to 55 And 35%) of the field capacity.
