摘　　要：将葡萄幼苗置于高温胁迫条件下,通过测定叶片中脯氨酸、叶绿素和可溶性糖的含量来研究葡萄幼苗的抗热、抗水分胁迫的能力。结果表明:热激3h可溶性糖的含量达到最大值。葡萄叶片脯氨酸的含量在高温胁迫下明显高于对照,而叶绿素的含量和可溶性糖的含量则随胁迫时间的延长呈现“低—高—低”的波动。实验结果表明在短时间内葡萄幼苗具有快速抗热的机制。In this test grape seedlings were be set under high-temperature conditions of coercion through which proline measurement leaves, chlorophyll and solubility to study grape seedlings sugar content of resist heat, water resistant coercive capacity. The results showed dramatic three-hour hot solubility achieve maximum sugar content. Grape leaves proline content is markedly higher than in the heat of coercion, and chlorophyll content and solubility sugar content is as a coercive extension of the ＂low-high-low＂ volatility. Grape seedlings in a short period of time results with rapid resist heat mechanism.
