摘要
应用环境扫描电镜对28份茄子栽培种及近缘种花粉形态、外壁纹饰等作了系统观察和比较分析。结果表明,所有供试材料花粉均为长球形,具3萌发沟,以等间距环状分布,沟延伸到两极;花粉外壁纹饰均为颗粒状。不同材料花粉粒在大小、外壁纹饰特征方面存在不同程度的差异,花粉粒大小可以作为推断茄子栽培种内不同果形品种演化的依据。对一些典型的花粉形态性状进行聚类分析,结果将茄子分为栽培种和近缘种两大类,聚类分析结果与传统分类结果具有一定的一致性。
Pollen morphology and exine ornamentation of 28 eggplant materials and their related species were examined under scanning electron microscope （SEM）. The results showed that the pollen shape of all the materials were pro[ate. They all had 3 colporates which annularly distributed in equal space, and ex- tended to the two poles. The pollen sculptural type of eggplant was granular. There were difference on pol- len grain sizes and sculptural features among different varieties. Pollen grain size could be as a basis to de- duce the evolution among different shape of eggplant cultivars. The cluster analysis was conducted on some typical pollen morphology, and the results showed that the studied materials could be classified into two clusters：cultivars and their related species. The result was similar tn that of traditional classification.
