Abstract
The experiment was conducted at the cage house in the Department of Plant Physiology, S.K.N. College of Agriculture, Jobner (Jaipur) to study the effect of brassinolide on physiological aspects of fenugreek (Trigonella foenum-graecum Linn) under drought conditions. Four fenugreek cultivars namely RMt-1, RMt-361, RMt-305 and Hissar Sonali were grown in ceramic pots under normal conditions till vegetative stage and then plants were sprayed with brassinolide (0.0, 0.25, 0.50, 0.75 and 1.00 ppm concentration) followed by half the plant population subjected to water stress by withholding irrigation. The observations were recorded at 7-days after first (pre-flowering) spray and 17-days after first spray of brassinolides. It was observed that 1.0 ppm concentration of brassinolide was most effective under both non-stress and water stress condition. It may be concluded that RMt305 was drought tolerant, among cultivars studied and brassinolide showed positive response towards all the physiological parameters by reducing the adverse effect of drought stress.
