采用选择典型样株和随机取样的方法,对杜仲皮含胶特性的个体变异规律及其与若干宏观性状的相关性进行了系统研究.结果表明,不同无性系的胸径、树皮厚度、树皮含胶率的差异均达到了极显著水平.杜仲无性系树皮的含胶率与木栓层厚度和木栓层占树皮厚度的百分比呈极显著的负相关关系,与胸径的大小呈显著的负相关关系.胸径生长量越大,木栓层越厚,杜仲胶的积累相对越少;杜仲胶密度与树皮含胶率和树皮密度呈极显著的正相关关系.

Individual variation of gutta-percha content in barks of Eucommia ulmoides and the correlations between gutta-percha content character in bark and several macroscopic properties were systematically studied by means of selecting the typical plants and random sampling. The result showed that the differences of DBH (diameter at breast height), the bark thickness and guttapercha content in bark were in significant level among various clones. The gutta-percha content rate among different Eucommia clones had a significant negative relation with the phellem thickness and the ratio of phellem to bark ...
