摘要
以辽宁兴城试点1983～1985年培育的3批侧柏种源试验苗木,共含23个混合种源和12个分家系的种源(共163个家系)为观测材料,连续4年研究了不同种源和家系的萌动期,高生长进程和停止生长期的差异,并分析了停止生长与越冬状况、试验点环境条件和苗高生长的关系以及移植对生长节律的影响。
The growth-rhythm of the seedlings of 23 provenances and 163 families belonging to 12 provenances were investigated. The relationships between growth cessation timing and winter hardiness of seedlings and the effect of transplanting on growth-rhythm were analysed.
