近年来,由于太谷核不育小麦细胞形态学工作的进展,已确认其花药败育的时期和过程,但对败育原因,报道尚少。太谷核不育小麦既然是无花粉型的核不育小麦,DNA又是核酸的主要成分,因此,研究太谷核不育小麦花药败育原因,首先应该研究核酸代谢。本文用生理学方法,研究了太谷核不育小麦与可育小麦花药的核酸代谢,探讨了核酸含量、核酸酶、G-6-P In recent years, due to the progress of cell morphology of Taigu nuclear sterile wheat, the period and process of anther abortion have been confirmed, but there are few reports on the reasons of abortion. Since Taigu nuclear sterile wheat is a non-pollen type of sterile wheat, DNA is the main component of nucleic acid. Therefore, to study the reasons for the anther abortion of Taigu nuclear sterile wheat, we should first study the nucleic acid metabolism. In this paper, the nucleic acid metabolism of Taigu nuclear sterile wheat and fertile wheat anthers was studied using physiological methods. The effects of nucleic acid content, nuclease, G-6-P
