| Abstract:
Prunus lannesiana Wils. (Carr.) var. speciosa (Ohshimazakura) is very important cherry tree as for rootstock of flower cherry and fruit cherry, smoke-dried materials of ham and bacon etc., and also the leaves for materials of typical Japanese cake (sakura mochi). This wild cherry trees are native to middle pacific area of japan. In general, seed germination is started in 8 months late after harvesting seeds. For example, store the seeds in soil till next february as soon as harvesting seeds in the middle of june, and sow it in the end of february, so that seed germination will be started in two or three weeks. So, for early seed germination and early growing up, the requirements of low temperature and storage periods had to be investigated. The main results were found out, that 3≈4°C/12≈16 weeks and 8≈9°C/12 weeks in wet condition storage were best for accelerating early germination. But dry condition storage and frozen storage were not good for germination. | |
