摘 要 :本文首先利用太谷小麦可育株证实了同一朵小花里的大孢子母细胞(EMC)和花粉母细胞(PMCs)减数分裂节律基本同步的现象。随后,以这种可育株作标准,与含 Tal 基因的孪生不育株比较,初步证实:该基因的存在对 EMC 的减数分裂节律和分裂相表征无明显影响;但对 PMCs 的减数分裂早在造孢细胞期或PMCs 减数分裂前的间期便显出它的阻遏
Abstract:This paper primarily uses the normal fertile plant of Taigu wheatto demonstrated that the meiotic rhythm of embrio sac mother cell(E-MC)and pollen mother cells(PMCs)in same floret is basically synch-ronism.Subsequently,take this fertile plant as a standard,comparewith the twin sterile plant includin
