effect of water supply on viability, chemical composition of grain and yield and its components of wheat
Abstract: Two pot experiments were conducted during 91/92 and 92/93 growing
Seasons. The amounts of water received by the plants were computed to be equivalent to 150,200,250,300 and 400 mm precipitation. Seed viability was evaluated under optimal and suboptimal conditions. Chemical composition, grain yield and yield component were estimated according to standard methods. The results of viability test revealed that the amount of water had insignificant influence on seed germination under optimal conditions in contrast with a significant effect under sub-optimal conditions (at-10 PMa osmotic stress and after aging the seed). The increase in the rate of water supply increased moisture, Fat, Ash, Crude fiber, PhosPhorus and Potassinm content, but, decreased crude protein nitrogen element and free amino acids of wheat grain. Further , seeds/contained high protein and NPK elements and produced under low water supplies were capable of withstanding stress conditions and had high germination percentage under sub-optimal conditions compared to normal seed produced under higher water supplies. However, low water supplies depressed seed yield as a result of lower number of spikes/plant and grain /spike.
