Popis:	Germinating seeds of Glycine max (L.) cultivar. L-65 (Dr. W.G, variety) were treated with 3H-thymidine at various times after seed soaking began at 25°C and the shoot apical meristem was squashed on slides. Then, microf luorography was carried out. The tritiumlabeled nuclei and mitoses were examined through the microscope. Consequently, it was suggested that most shoot apical meristem cells begin the DNA synthesis at 22-24 h after soaking of seed and lasts for 5 h, while mitosis starts at 26-28 h and the period is about 2.5 h. It was further supposed that shoot apical meristem cells stays at G0 or G1 period in the dormant seed.
