中国黄连木性状变异及类型划分

本文采用典型和随机抽样调查的方法，在太行山中黄连木中心产区对黄连木的树形，发枝力，果穗，亲实，种子等１８个性状进行了调查和统计分析，黄连木性状变异幅度大，变异性状有的相关紧密，有的松散，并且有些性状有年龄差异。黄连木多为天然实生繁殖，后代多为异交系，故该区多态型类型种类繁多，为选择优良类型和遗传改良提供了丰富的种质资源。

Character Variation and Variety Classcfication of Pistacia Chinesis Bunge

Typical sa well as random sampling were adopted in this maper to investigate and analyse 18 characters such as shape,sprouting capability,fruit and seed etc of P. chinesis Bunge from its center living region in Taihang mountains.The results showed character variation range of P. Chinesis Bunge was very wide,some of the varied characters were closely velated,some werent.The same Character differed with ages P. Chinesis Bunge Propagates with seed naturally and most of its clecedants were hybrid .So there were many variedtis with palymorphism in this area which could Provide rich gene resources for superioer varicty selections and genetii improvement.
