系统观察了杏(Prunus armcniaca L.)80个品种的花粉形态并进行聚类分析,结果表明,1.杏品种花粉大小、形状比较相似,但也存在一定差异。2.花粉表面纹饰多样。品种间差异很大,据此,将供试的杏品种分成3大类。 3.杏李((Prunus Simonii Carr.)花粉形态介于李(Prunus salicina Lindl.)和杏之间,进一步证明是李和杏自然杂交种的推论。4.新疆的阿克西米西及馒头玉吕克两个品种与华北生态群的其它品种之间的类间距离较大,分别为11.76和8.35,故亲缘关系较远,其起源问题有待进一步研究。5.根据表面纹饰并结合聚类分析对杏品种进行分类是一个有效的方法。但要对品种进行全面而详细的分类,还应结合品种的植物学特性和经济生物学性状。6.红玉杏与玉杏、大麦黄与小麦黄等品种之间的类间距离最小,分别为0.163和0.302,亲缘关系甚近或很可能是同物异名。
Pollen morphology of 80 cultivars of Prunus armcniaca L. was systematically observed and clustered. The results showed that the pollen size and shape of apricot cultivars were similar, but there were some differences. Pollen surface decoration variety. Varieties vary widely, according to which, will be tested apricot varieties into 3 categories. 3. Prunus Simonii Carr. The pollen morphology is between Prunus salicina Lindl. And apricot, which further proves to be the inference of natural hybrids between Li and apricot.4. The distance between the two cultivars of Yuluk and the other species in North China ecotones is relatively large, which is 11.76 and 8.35, respectively, so their genetic relationship is far away from each other and their origin needs to be further studied.5.According to the combination of surface ornamentation and clustering It is an effective method to classify apricot varieties.But to conduct a comprehensive and detailed classification of varieties, we should also combine the botanical characteristics and economic and biological characters of the cultivars.6.Hongyu apricot and jade apricot, barley yellow and wheat Huang and other species between the smallest distance between classes, respectively, 0.163 and 0.302, very close relatives or may be synonym.
