Effect of root pruning on transpiration loss and drought tolerance in rice (Oryza sativa)



Effect of root pruning on transpiration loss and drought tolerance in rice (Oryza sativa)



Indian Journal of Agricultural Sciences 64(10): 708-710



In studies in 1987 and 1988 with rice N 22 grown in pots, roots were pruned by 0, 25, 50 or 75% at the tillering stage and pots were or were not watered and covered with a polyethylene sheet to prevent evaporation. A similar root pruning experiment was also conducted with plants grown in solution culture. In unpruned plants, transpiration decreased at wilting. Transpiration decreased with increased root pruning and this delayed the onset of wilting in water stressed plants.
