Summary
The leakage of ions from detached leaves and chlorophyll degradation after exposure to PEG 6000 and elevated temperature were assessed as possible indicators of drought and heat tolerance in wheat Exogenous application of cytokinin showed concentration dependent increase in cell membrane and chlorophyll stability in drought sensitive (Kalyansona) and drought tolerant (C-306) cultivars of wheat at anthesis and boot stages which were significantly correlated with the grain yield.
