| 摘 要： | 对春季叶和秋季叶杜仲胶含量及水溶物含量的测定结果表明，４１种无性系间的含胶量与水溶物含量都存在着极显著差异。杜仲叶中胶的积累和水溶物的积累具有不同规律。春叶的含胶量约为秋叶的２倍，单位面积秋叶的水溶物含量约为同面积春叶的３倍。为选育优良杜仲无性系和适宜的采叶时间提供了依据

| Abstract: | The contents of gutta and water solubles in the spring and autumn eucommia leaves were determined. There existed marked differences in the contents among 41 eucommia clones, and different accumulation patterns of gutta and water solubles. Gutta contents of the spring leaves were about twice as much as the autumn leaves. The contents of water solubles of autumn leaves in per unit area were about 3 times as much as the spring leaves. The results provide scientific basis for selecting excellent clones of Eucommia ulmoides and suitable time of gathering the leaves. |
