干旱胁迫对甜高粱幼苗渗透调节物质的影响
Effects of Drought Stress on Osmoregulation Substances in Sweet Sorghum Seedlings
摘要
Abstract
To investigate effects of water conditions on osmoregulation substances in seedlings of sweet sorghum and grain sorghum, potted Liaotian 1 (a sweet sorghum variety)and Liaozal0 (a grain sorghum variety)seedlings were subjected to different water treatments. The results showed that with water stress intensifying, the sweet sorghum variety exhibited higher leaf water-retention potential,proline content and soluble protein content,but lower content of soluble sugar and malondialdehyde,than the grain sorghum variety. It would appear that both sorghum varieties were able to adapt to drought stress through accumulation of osmoregulation substances: The sweet sorghum variety used primarily proline and soluble proteins as osmoregulation while the grain sorghum variety relied more heavily on soluble sugars.关键词
