不同地理唐古特白刺家系花粉形态多样性研究
Pollen Specificity Analysis of Nitraria tangutorum in Different Geographic Families
为了解唐古特白刺种内花粉形态的多样性,对不同地理的 6 个家系花粉形态进行研究。本研究材料来源于 2011 年收集野外种子并种植在同一环境条件下。采集新鲜花粉并进行冷冻干燥处理,通过扫描电镜进行拍照、测量,后对 6 个家系间的测量数据进行方差分析、主成分分析和聚类分析。唐古特白刺花粉为单粒形式存在,中等大小花粉粒,长球形,具三孔沟,萌发沟宽,存在连接,萌发沟脊面为两极小,中间大,呈"凸"形增大,纹饰类型为条状、脑状,并没有构成图案;家系花粉在萌发…查看全部>>
In order to understand the species diversity of Nitraria tangutorum,the pollen morphology of 6 families from different geographical regions was studied.The materials in this study were collected in 2011 and planted in the same environment.The fresh pollen was freeze-dried,photographed and measured by scanning electron microscope(Sem),and the measured data of 6 families were analyzed by variance analysis,principal component analysis and cluster analysis.the p…查看全部>>
