| 摘 要： | 通过对华北落叶松初级种子园5年的物候观测,编制了年物候周期表。从种子园群体和无性系个体两方面,揭示出华北落叶松年物候周期规律。并分析阐明了物候期与气温和活动积温之间的相关性。还对无性系个体间物候的异同性及雌雄球花的相遇问题作了剖析。本项研究对种子园制订良种生产计划和经营管理具有重要价值。

| Abstract: | Through 5 years of phenological observations on Larix principis-rupprechtii Mayr. in primary seed orchard and studies on population and individuals of clones, the annual periodic phenological laws were revealed and the annual phe-nological periodic table was drawn up. The correlation between various phenophases, the air temperature and active accumu-lated temperature were analyzed and expounded. The authors also analyzed the similarities and differences of phenophases among clonal individuals as well as the blooming properties of male and female flowers at the same time. This study could pro-vide theoretical reference for working out the production plan of improved varieties and other management measures in seed orchard of Larix principis-rupprechtii. |
