| 摘 要： | 对近年来我国引进和选育的穗重型小麦品种(系)的冷温特征进行了研究。结果表明,穗重型小麦除冠层温度高于对照(冷型小麦陕299和小偃6号)外,叶片输出功能期、净光合速率、旗叶叶绿素含量、蒸腾速率均低于对照;另外,穗重型小麦潜在库容量比冷型小麦大,但其饱满指数小,这是穗重型小麦实现高产潜力的重要制约因素。

| Abstract: | Cold typal characteristics of some high spike weight wheat variesties or lines which were breeded and transfered in recent years in China were studied.The results showed that,the canopy temperature of the high spike weight wheat was higher than that of CK (Shaan 229 and Xiaoyan No.6);the output functional periods of the leaves were shorter than that of CK,net photosynthetic rate,transpiration rate and flag leaf chlorophyll content were lower than those of CK;though the latent storage capacity of high spike weight wheat was more than that of CK,but its plumpness index was lower,they were the major factors restricting high spike weight wheat to realize its potential of high yield. |
