运用模糊动态聚类法划分肃北中亚沙棘的种质类型

Dividing Seed Type of Central Asia Common Seabuckthrou in North Gansu Province by Using Fuzzy Dynamic Assembly Method

以肃北县党河河谷３４个中亚沙棘样本的调查材料为素材，运用模糊动态聚类法，以果实颜色、形状、大小、百果重、果柄长度及其种子大小、形状。千粒重为划分指标，通过统计聚类，将该地中亚沙棘分为１０个类型，并按果实颜色、形状；大小特征逐一进行了命名。目的是在沙棘类型划分上探索新途径，为沙棘育种和开发利用提供依据。

Bsaed on investigative materials of 34 samples of Central Asia common seabuckthron from Danghe valley in North Gansu Province,according to the indexes of colour, form,size of fruit,the weight of 100 fruits,length of fruit-stem;size, form of seed and weight of 1000 seeds, the paper divided the Central Asia common seabuckthron into 10 type by using fuzzy dynamic assembly method, and named them in the light of the chracteristics of colour, form and size respectively.The aim is to research a new way to divide the type of common seabuckthron and provide basis for seeding and using of common seabuckthron.
