| 内容記述 | We measured the final germination rates of achenes, the number of days needed to accomplish 50% of the final germination（T50）, and mortalities under various temperatures in the range 5 to 25℃for five understory peren-nial herbs（four species with large achenes of ca. 10 mg weight : Pertya robusta, P . triloba, P . rigidula and Ain-sliaea acerifolia var. subapoda, and one species with small achenes（1mg）: A. apiculata）to investigate variation of these traits. Achenes were collected in Ogawa and Mito in Ibaraki Prefecture, and in Iwakuni in Fukui Prefec-ture. T50 ranged from 35 to 76 days at 5℃and became shorter with increasing temperature. The final germina-tion rates of most samples were over 95%. Ainsliaea acerifolia had the longest T50（76 days）and the lowest final germination rate（86.1%）at 5℃, showing a dormant ability to some extent. Moreover, A. apiculata possessing small achenes showed a lower final germination rate（83%）at 25℃, and dormancy at higher temperatures. Fun-gal attack was thought to cause the death of achenes during the germination period, and mortalities increased with increasing temperature. However, there were no significant differences in final germination rates and T50s between two populations of P . robusta from Ogawa and Mito, though the Ogawa population had a higher mor-tality than the Mito population（27% vs. 18% at 25℃）. Mortalities were higher in P . triloba and P . rigidula than in the other species. There were intra- and interspecific variations of temperature dependency of achene mortal-ity during germination, and these variations may be one of the factors limiting the distribution of each species. | |||||
