The DNA content and incorporation of [(3)H]thymidine into DNA have been studied during the development of Triticum aestivum (L.) embryo at various stages of seed germination up to 102 h (18°C). The DNA content of the embryos increased in a rhythmic way, when superimposed on an increasing basal content of DNA from 12 h onwards of germination. A temporary depression in DNA content was observed before the peaks of cell division (which has earlier been published by the author). The peaks of [(3)H]thymidine incorporation coincided with the peaks of cell division.
在小麦种子萌发的各个阶段,研究了(3)H 胸腺嘧啶核苷掺入 DNA 的 DNA 含量和整合情况,直至 102 小时(18°C)。胚胎的 DNA 含量呈节律性增加,同时在萌发 12 小时后 DNA 的基础含量也在增加。在细胞分裂高峰期之前,DNA 含量暂时下降(作者之前已经发表过)。(3)H 胸腺嘧啶核苷掺入的高峰期与细胞分裂的高峰期相吻合。
