摘  要:
对黑荆树两个试验点25个种源3年半的观察,结果表明:不同种源种子发芽率,苗高存在明显差异,各种源年周期枝梢生长有三次高峰期,生长量与日气温、月降雨量变化基本一致。本文还比较分析了各种源树高、胸径、树皮量、材积以及耐寒性等性状。

摘  要:
A three-and-half-year observation was made of 25 provenance samples of mearns acacia (Acacia mearnsii) in two test plantations. The results indicated; a) The germination percent and the seedling height varied greatly from sample to sample, b ) each sample annually produced three maximum shoot growths, which changed basically with the monthly temperature and rainfall. Each sample's bark percent, volume and frost-resistance were compared.
