赵明等首次利用透明塑料薄膜简棚进行田间诱导雄性不育的研究在小麦上取得了良好的结果后,系统研究温度与小麦雌、雄器官育性的关系。然而对叶片在此条件下的生理变化还缺乏系统研究。杀雄过程中,小麦叶片的伤害程度及其以后的恢复能力如何?是直接关系到杀雄后小麦干物质生产,进而影响制种产量的问题。本文从叶片的光合强度、叶片电解质渗漏量、叶绿素含量变化,分析短时高温处理后,叶片的伤害程度和恢复能力及对干物质生产的影响。 1 材料与方法 Zhao Ming et al. First conducted field-induced male-sterile experiments using transparent plastic film sheds. After good results were obtained on wheat, the relationship between temperature and fertility of female and male was systematically studied. However, the physiological changes of leaves in this condition are still lack of systematic research. Killing male process, the degree of damage to wheat leaves and its ability to restore after? It is directly related to the killing of dry matter after the production of wheat, and then affect the production of seed production. In this paper, the changes of photosynthetic intensity, leakage of electrolyte in leaves and content of chlorophyll in leaves were analyzed. The effects of short-term high temperature treatment on injury degree and recovery of leaves and their effects on dry matter production were analyzed. 1 materials and methods
