Abstract:
The role of brassinolide on chickpea (Cicer arietinum L.) in reference to physiological aspects was studied and evaluated under water deficit condition. Two varieties of gram namely RSG-888 & RSG-895 were grown in pots. After the phase of vegetative growth completion plants were sprayed with brassinolide at 0.0, 0.1, 0.5 &1.0 ppm conc. respectively. After that half of the total number of plants subjected to water deficit environment by withholding irrigation or water supply & then experiment shows the observation which was recorded at 50% flowering & 50% podding stages. Brassinolide (1.0 ppm) significantly increased relative water content, chlorophyll stability index, photosynthetic rate, transpiration rate, stomatal conductance, protein and proline content in both varieties under irrigated and water deficit conditions. The conc. of 1.0 ppm shows the most effectiveness result in overcoming towards adverse conditions affected under water deficit. Seed yield also highly correlated with physiological attributes under water deficit or scarcity of water supply conditions. It is concluded that RSG-888 variety of gram was mediated through physiological adaptation under water deficit.
