烯效唑对淹水胁迫下大豆农艺性状及生理生化指标的影响
Effects of uniconazole on alleviation of waterlogging stress in soybean
摘要
Abstract
With sub - indeterminate soybean varieties Kenfeng 14 and Kenfeng 16 as materials,a pot experi-ment was conducted to analyze the effect of uniconazole on agronomic traits and physiological and biochemical char-acteristics of soybean under waterlogging stress. Five days after spraying uniconazole at early flowering period,wa-terlogging stress was performed for five days,and then returned to normal water. The results showed that the growth of soybean was inhibited by flooding stress,the plant height,the accumulation of dry matter in plant leaves,peti-oles,stems and roots and antioxidant enzyme activities were decreased,but the stem diameter was increased. Spra-ying uniconazole could effectively alleviate plant dry matter weight reduced under waterlogging stress,and signifi-cantly improve the activity of soybean antioxidant enzyme system,reduce MDA content,increase proline content in leaf and root,and soluble sugar and starch accumulation in root. All these could improve soybean production by in-crease their waterlogging resistance and returned to normal after moisture accumulation.关键词
