项目摘要

Phenology of adult trees had been investigated for three years (1996 - 1998) at 11 study sites, 9 university forestsﾟCin total. And provenance test Sites were established at each university forests with seeds taken from mother treesﾟCselected from the adult trees in each university forests. The phenological characteristics had been surveyed on seedlingsﾟCin provenance test sites. The study contents in detail were as follows.1. Phenology of adult trees Timing of flushing, flowering, and amount of leaf, flower and acorn on tree crown byﾟCeye measurement. And litter traps were set under investigated trees for measurement of defoliation, fallen flowersﾟCand fallen acorns. For analysis between the phenological timing and environment condition, air temperature underﾟCthe crown was measured.2. Establishment of provenance test sites : Provenance test sites were established with seeds of Quercus mongolica var. grosseserrata, Quercus serrata, and Quercus acutissima at Hokkaido Univ. (Uryu and Nakagawa), Yamagata Univ. (Kaminagawa), Tsukuba Univ. (Yatsugatake), Univ. of Tokyo (Hokkaido and Chichibu), Tokyo Univ. of Agric. and Tech. (Karasawayama, Ohtaniyama, Kusaki and Saitama), Shizuoka Univ. (Kamiatago), Kyoto Univ. (Kamigamo), Tottori Univ. (Hiruzen) and Kyushu Univ. (Fukuoka).3. Phenology of seedlings in provenance test sites Timing of germination and amount and number of leaves of seedlings were surveyed in each provenance test site. Change in leaf color from summer to autumn before defoliation measured by SPAD meter (Minolta SPAD-502). For analysis between the phenological timing and environment condition, air temperature in provenance test sites was measured.Above these measurements, phenological characteristics were compared among adult trees and provenance. The most important factor was accumulated temperature, and longitudinal difference among study sites slightly affected on timing of phenological change.

1996年至1998年，在11个研究地点共9个大学林ﾟCin进行了3年的成龄树木物候调查。并在各大学林建立种源试验点，种子取自母树ﾟC，选自各大学林的成年树。对苗木ﾟCin种源试验点的物候特性进行了调查。具体研究内容如下：1.研究内容。成年树的物候期、开花时间和树冠上的叶、花和橡子的数量用ﾟ猫眼测量。在被调查的树木下设置了凋落物陷阱，用于测量落叶、落花ﾟC和落果。为了分析物候时间与环境条件之间的关系，测量了ﾟ树冠下的气温。种源试验点的建立：以蒙古栎种子为材料，建立种源试验点。北海道大学的粗果栎属、锯缘栎属和麻栎属植物。(Uryu和Nakagawa)，山形大学。(Kaminagawa)，筑波大学。(Yatsugatake)，大学。东京大学东京分校(北海道和七步道)阿格里克的名字。和科技。(Karasawayama、Ohtaniyama、Kusaki和Saitama)，静冈大学。(神户)，京都大学。(Kamigamo)，鸟取大学。和九州大学。(福冈).对种源试验点苗木物候、发芽时间、各试验点苗木叶片数和叶数进行了调查。用SPAD仪(美能达SPAD-502)测量落叶前从夏季到秋季的叶色变化。为了分析物候时间与环境条件之间的关系，对种源试验点的气温进行了测量，并在此基础上比较了成年树和种源的物候特征。最主要的影响因素是积温，不同研究地点之间的纵向差异对物候变化的时间影响不大。
