The pollen morphology of 30 tea varieties from main cultivated provinces of China and one from Japan was examined under microscope and scanning electron microscope . Based on 14 characters of pollen morphology, the 31 varieties were classified with fuzzy clustering analysis (FCA). The main results obtained were as follows : (1)The pollen characteristics of 31 varieties were described as four main aspects. The size of pollen grains was middle or big types; most of them was prolate in shapes;the aperture was N3P4C5....

The pollen morphology of 30 tea varieties from main cultivated provinces of China and one from Japan was examined under microscope and scanning electron microscope . Based on 14 characters of pollen morphology, the 31 varieties were classified with fuzzy clustering analysis (FCA). The main results obtained were as follows : (1)The pollen characteristics of 31 varieties were described as four main aspects. The size of pollen grains was middle or big types; most of them was prolate in shapes;the aperture was N3P4C5. Their os, which had several shapes, was big and long ; on the equatorial face, there was reticulate or obscurely ornate ornametation, the size and shape of their muri and lumina were varied. In regard to pollen morphology, there was only a little difference, so it could be acceptable to say that all these varieties belong to one species Camellia sinensis (2) The result of FCA showed that the 31 varieties might be devided into 6 groups. In general, the varieties derived from adjacent areas shared the same group. (5) The affinity relationship of some varieties was discussed by their similar coefficient.

用光学显微镜和扫描电子显微镜对31个茶树品种(系)的花粉形态进行研究,并以14个花粉形态性状进行模糊聚类分析,结果表明:茶树花粉粒为中粒或大粒,多为长球形、三孔沟,内孔大、横长,赤道面观多为网状或拟网状纹饰,网眼和网脊大小、形状有一定差异,但品种(系)间花粉形态的变异程度较小.31个茶树品种(系)经聚类被分成六个组,基本上以原产地相近的品种(系)聚在一起,从相似性系数的大小可见茶树品种(系)间的亲缘关系之密切程度.

The leaves,veins,lenticels,twig clors and flowers of 64 Chinese chestnut clones or Strains were observed in the Chinese chestnut orchard of Tonglu Forest Farm,Zhejiang Province ,and the apertures,shapes and or-namentation of pollen to 20 ones among them were scanned by use of elec-tron microscope(3000 times).Some diversities among the clones or strains were found in the shape,tickness and hair of leaf, lent icular density and color of twig.The polar faces and ornamentation of pollen were basically same,but...

对桐庐林场板栗园内的64个板栗无性系或品种的叶、叶脉、枝条皮孔、枝条颜色、雄花序、雌花以及20个品种花粉的萌发器、形状和纹饰进行了观察分析,发现各品种之间叶形、叶厚、被毛程度、枝条皮孔数、枝条颜色有一定的差异;花粉极面观形状基本一致,但花粉萌发沟孔深度、花粉赤道面形状及花粉粒大小均有一定程度的差异。

Variance regularity of Corylus heterophylla pollen morphology is sumed up according to considerable samples of 5 species under controlling conditions,and sampling method is approached on quantitative researching.The results showed that the morphological indices of Corylus heterophylla pollen are variable with sampling conditions.The samples used in quantitative researching should be selected from different locations(include all of sites),number of location should be more than 3 in Northeast of China.Shape index of equatorial face(shortest distance between apertures/corresponding equatorial length),number of apertures,shape index of pollen(poleaxis length/equatorial length) are better than others.

通过5种限制条件的大量取样,总结出榛子花粉形态的变异规律,进而探讨了榛子(CorylusheterophylaFisch.)花粉形态学定量研究的取样技术.结果表明:花粉形态指标随不同取样条件发生变异;定量研究取样样点首先应考虑采用不同地点(包括各生境)的样本,在东北地区不能少于3个采样地点;分析指标以赤道面形状指数(最短的萌发孔间距离/所对赤道轴长)、萌发孔数目、花粉形状指数(极轴长/赤道轴长)为最佳.
