小麦花药生长在叶鞘与颖稃的包围之中,具有特殊的生理生态条件,在花粉母细胞减数分裂前后呈绿色,随着花粉粒的发育,绿色逐渐减弱。小麦花粉为什么呈绿色?绿色的小麦花药能否进行光合作用?它与太谷核不育小麦败育是否有关?这些问题均未见报道。为探讨小麦花药的光合作用以及和太谷核不育小麦的关系,对小麦花药的光合特性进行了研究。一、试验材料与方法1.以太谷核不育小麦的可育株和不育株花粉母细胞减数分裂以后的绿色花粉为供试材料,育性经过鉴定,是(Tal×农大139)×农大139遗传性稳定的高代材料,取自山
Wheat anthers are surrounded by leaf sheaths and ridges. They have special physiological and ecological conditions. They are green before and after meiosis of pollen mother cells. With the development of pollen grains, the green color gradually weakened. Why green wheat pollen is green? Is green wheat anther photosynthesis? Is it related to the abortion of Taigu nuclear sterile wheat? None of these problems have been reported. In order to investigate the photosynthesis of wheat anthers and the relationship with the Taigu nuclear sterile wheat, the photosynthetic characteristics of wheat anthers were studied. First, the test materials and methods 1.There were green pollens after the meiosis of the pollen mother cells in the fertile and sterile plants of the Guigu nuclear sterile wheat. Fertility was identified as (Tal × Nongda 139) × Nongda 139 high genetic stability of the material, taken from the mountain
