The effects of the temperature and other several conditions of the seed of nine species in Fagaceae for planting on germination

In order to clarify the effects of storage term and post-storage temperature on germination of the seeds of nine species in Fagaceae, germination speed and germination rate were examined using the seeds stored under a wet (75%RH) and cold (4°C) condition. Experimental conditions were as follows.(1) Post-storage temperature: 9°C, 16°C, 23°, 30°C and 35°C.(2) Storage term: long (127-175 days) and short (15-70 days). Germination speed and germination rate of Quercus myrsinaefolia and Q. acuta were higher in long-term storage. Germination speed of Q. glauca was higher in long-term storage. On the other hand, germination speed and germination rate of Q. serrata and Castanopsis cuspidata var. sieboldii were lower in long-term storage. Germination speed and germination rate of Q. salisina were the highest at 23°C, and those of Q. gilva were the highest at 16°C. Germination rate of Q. acutissima under temperatures between 9 and 30°C were over 80%. Germination speed and germination rate of Pasania edulis were the highest at 9°C and 30°C, respectively. Each species of Fagaceae had their own germination characteristics affected by temperature. And geographical difference of germination characteristics within a species were not clear.
