چکیده

Spring leaf phenology is an important event for trees to determine carbon fixation during the growing season. However, less understood about intraspecific variation in spring and its relationship with temperature requirements of conifers, which problematic accurately predicting influence climate warming on conifers. I monitored bud burst timing degree days required seedlings large individuals Abies sachalinensis (fir) Larix kaempferi (larch) over two seasons northern Japan. Contrary my expectation, small were similar or larger than those fir larch. Consequently, was later that Even when conifer species are their early stage, requirement not necessarily individuals, case many broad-leaved species. These results indicate these coniferous species, ontogenetic differences necessary be considered response communities change.

High autumn temperature delays spring bud burst in boreal trees, counterbalancing the effect of climatic warming.

The effect of temperature during short-day (SD) dormancy induction was examined in three boreal tree species in a controlled environment. Saplings of Betula pendula Roth, B. pubescens Ehrh. and Alnus glutinosa (L.) Moench. were exposed to 5 weeks of 10-h SD induction at 9, 15 and 21 degrees C followed by chilling at 5 degrees C for 40, 70, 100 and 130 days and subsequent forcing at 15 degrees C...
