为了更好 地认识矮 紫杉 营 养 器官 的 生 长规 律， 于１９９５ ～１９９６ 年定 株 对 其进 行 了研 究。结果表 明： 矮紫 杉的地径 生长缓 慢， 在年 生长周期 中有两 次生长高 峰， 而１ ａ 生枝 径相对生 长较快。枝 条的高 生长时间 较短， 从４ 月 上旬开 始到６ 月上 旬结 束， 整 个生 长过 程呈 单峰 曲线，且顶枝 的生长明 显地快 于侧枝。
In order to better understand the growth of vegetative organs of short-yew, we studied it from 1995 to 1996. The results showed that the diameter of shortwave growth was slow, and there were two growth peaks in annual growth cycle, while the branch diameter of relative growth rate was relatively fast in 1 year. The growth of shoots was relatively short. From the beginning of April to the end of June, the whole growth curve showed a single peak curve, and the growth of top branches was obviously faster than that of the branches.
