| 摘 要： | 为探究变温处理对小麦种子产生的生物学效应,采用对照试验法对小麦种子进行不同梯度的变温处理。结果表明:变温处理可以促进小麦种子的发芽,使其发芽率升高;另外,变温处理明显影响了已发芽小麦苗细胞内含物的含量,其中,可溶性糖和蛋白质含量经处理后呈递减趋势,核酸和叶绿素呈增加趋势,这表明底物的净含量减少但总合成量增加,即小麦的代谢速率增加。因此,变温处理提高了小麦的发芽率并且明显提高了小麦苗的代谢速率。

| Abstract: | In order to explore the biological effect of changing temperature on wheat seeds,wheat seeds trented with different changing temperature were studied by using contrasting method.The result showed that changing temperature could promote the germination of wheat seeds and improve their germination percentage.In addition,changing temperature could affect the content of cell inclusion significantly.The content of soluble sugar and protein decreased,while that of the nucleic and chlorophyll increased.It showed that it decreased the net content of substrate but increased the synthesis of substrate.So changing temperature could improve the germination percentage and the metabolic rate of wheat. |
