Abstract

Bud burst timing and frost tolerance were examined in Fagus crenata Blume and Quercus mongolica Fisscher ex Ledeb ssp. crispula (Blume) Menitsky, which are dominant species in the cool-temperate forest zone in Japan. The northern limit of distribution of the former species is within Kuromatsunai, Hokkaido and the latter extends its territory throughout to the northeast and interior of Hokkaido. The temperature dependence of the bud burst process was observed in Sugadaira Heights, Nagano Prefecture, for seven years. An experiment on frost effects on leaves for both species was conducted. Fagus crenata initiated bud burst earlier than Q.mongolica ssp. crispula in spring, although a strong thermal dependence of the bud burst process was observed in both species. The first leaf unfolding stage occurred on 12 May for F.crenata and on 27 May for Q. mongolica ssp. crispula. The average thermal times (TTs) for the leaf unfolding stage were 113±11℃ day for F. crenata and 182±16℃ day for Q. mongolica ssp. crispula. Experiments on freezing tolerance of winter buds and unfolded buds were carried out using a freezer and a natural-radiative-cooling box, which was newly devised for this experiment. The winter buds and buds in swelling stage were tolerant to freezing but buds in the leaf unfolding stage and the new shoot stage were severely damaged and were unable to recover. Shoots of Q. mongolica ssp. crispra formed lateral buds, which developed leaves if apical buds were damaged. These results suggest that F. crenata may not be able to disseminate in regions which may experience frost after the TT of a 113±11℃ day has occurred, bu Q. mongolica ssp. crispula can disseminate due to its delayed bud burst date and can regenerate shoots from lateral buds.
