10个农家品种梨花粉形态扫描电镜观察

利用扫描电镜和光学显微镜系统观察了10个农家品种梨花粉的外部形态和外壁纹饰;在对其花粉形态进行电镜观察研究的基础上,对花粉6个数量性状进行了聚类分析.结果表明：这些农家品种梨花粉粒大小属于小至中等范围;除方山飘梨、砂梨和他批梨等个别品种为超长球形外,其余品种属于长球形;10个农家品种梨花粉均属于N3P4C5型,萌发孔沟均为3条,孔沟几达两端,沟底未观察到有孔的痕迹;其侧面观为长椭圆形或椭圆形,极面观为3裂三角形或近圆形,赤道面观均为椭圆形,呈裂开状;表面具条纹状或网状纹饰和纹孔.根据聚类分析的结果推测：方山飘梨、汉源白梨、面包梨、桂花梨和大叶雪梨属于白梨系统;他批梨属于砂梨系统....

Using scanning electron microscopy and optical microscopy system,morphology and exine ornamentation of 10 local pear varieties were observed; Cluster analysis on six quantitative traits was done baaed on results of pollen morphology observation study.The results showed that：pollen size range of these local pear varieties was from small to medium; Most of local pear varieties were prolate except Fangshanpiao pear and Chinese sand pear and Tapi pear which were perprolate
