| 摘 要： | 利用扫描电镜观察8个怀地黄不同主栽品种花粉粒形态及表面纹饰,数据采用SPSS统计软件分析.结果根据花粉粒大小可分为大型花粉粒(长34.33～36.02μm,宽18.12～19.05μm)包括85-5、怀地2号和怀地3号,中型花粉粒(长36.93～37.80μm,宽17.14～17.40μm)包括北京1号、生津和北京3号,小型花粉粒(长31.38～36.06μm,宽16.02～16.23μm)包括沁怀和怀地1号;根据花粉粒网眼密度可分为高密度(1.5～1.52个·μm-2)包括北京1号和怀地3号,中密度(0.73～1.20个·μm-2)包括生津,北京3号,85-5和怀地1号,低密度(0.61～0.62个·μm-2)包括沁怀和怀地2号.表明不同主栽品种怀地黄花粉粒的大小、网眼的密度、大小和深浅等均有一定的差异.

| Abstract: | The scanning electron microscope(SEM) was applied to observe and compare the morphological characteristics of the pollens and sculpture type of pollen surface of different cultivated varieties of Rehmannia glutinsa.The data were analyzed by SPSS software.Based on the pollen size,pollens can be divided into large pollen grains(length of 34.33~36.02 μm,width of 18.12~19.05 μm) including 85-5,Huaidi No.2 and Huaidi No.3,medium pollen grains(length of 36.93~37.80 μm,width of 17.14~17.40 μm) including Beijing No.1,Shengjin and Beijing No.3,small pollen grains(length of 31.38~36.06 μm,width of 16.02~16.23 μm) including Qinhuai and Huaidi No.1: Based on mesh density,pollens can be divided into high density(1.5~1.52 μm-2) including Beijing No.1 and Huaidi No.3,medium density(0.73~1.20 μm-2) including Shengjin,Beijing No.3,85-5 and Huaidi No.1,low density(0.61~0.62 μm-2) including Qinhuai and Huaidi No.2.The results showed that some differences in pollen size,mesh density,size and depth among them. |
