The capacity of the soybean plant to survive wilting is an important factor in drought resistance. Drought resistance in soybeans was characterized according to physiological parameters. The degree of resistance by soybean plants to water loss was determined, ranging from 40.7 to52.3 percent in the soybean cultivars tested. The stomatal behavior inresponse to water sterss was abserved. The effect of applying abscisicacid to prevent water loss was also studied. The effect of irrigation on soybean production in the field was investigated. Irrigation increased the: plant height; leaf area; dry weight of leaves roots, and stems; length of primary root; and number of leaves. Increased leaf water potential contributed to plant growth throgh greater turgidity and also minimized the effect of water stress in reducing photosyntesis. The increase in the number of leaves (17.8 percent) was less than that in leaf area (53.5 percent). Irrigated soybeans developed larger leaves, mainly in the upper part of the plant. This was confirmed by a greater dry weight for the leaves (49.7 percent). The effect of irrigationwas more pronounced on the growth of aerial parts (49.4 percent) than on roots (36.5 percent). The increase in production by irrigation was 123 kilograms per hectare. That value is not very high, possibly because there was no water sterss on the crop at the pod-filling stage in this experiment. |
