Aged seeds of soybean (Tachisuzunari) which exhibit a lower germination rate than the new seeds showed a decrease of the mitotic index and delay of the first cell division in the root tip meristem. The decrease of the tRNA content in the embryos of aged seeds was detected by fractionation of RNA by polyacrylamide gel electrophoresis. The germination rate and the first cell division frequency of the aged seeds increased by the 6-benzylaminopurine (6-BAP) treatment. The tRNA content in the embryos of aged seeds was also increased by the 6-BAP treatment. The quantity of RNA Ieached from the aged seeds which increased during germination reduced by the 6-BAP treatment.
