Elucidation of factors influencing the annual variation of height growth in cold-temperate conifers

本研究的目的是检测和验证寒温带针叶林中两种优势冷杉种冠层树木高度年变化的影响因素。冷杉种球芽发育期间的气温是影响种球果生产的重要因素，导致其株高的年际变化。在沙沙林松中，种球芽发育期间的气温也与高度生长有关。但球果生产对株高生长的影响有待进一步验证。

The objective of this study was to detect and verify factors influencing the annual variation in height growth of canopy trees of two Abies species dominant in cold-temperate conifer forests. In Abies mariesii, air temperature during seed-cone bud development was found to be an important factor influencing seed-cone production, resulting in the annual variation in height growth. In A. sachalinensis, air temperature during seed-cone bud development was also suggested to be associated with height growth. However, the influence of seed-cone production on height growth needs further verification.
