摘要
目的:比较山东主产区忍冬5个农家品种花粉形态特征,为品种划分及良种选育提供依据。方法:扫描电镜观察花粉粒形态及表面纹饰,数据采用SAS 9.1统计软件分析。结果:忍冬不同农家品种花粉粒大小、萌发孔及表面刺突的长短、疏密等均有一定差异。其中,大鸡爪的花粉粒及其萌发孔长度最大,分别为61.97μm×61.79μm,18.03μm,红梗子的花粉粒及其萌发孔长度最小,分别为57.46μm×57.29μm,16.55μm。结论:花粉粒形态特征可作为忍冬不同农家品种划分的参考。
Objective： To compare morphological characteristics of pollen of Lonicera japonica in different cultivars cultivated in Shandong and provide a basis for distinguishing different cultivars and selecting fine breeding.Method： The scanning electron microscope（SEM） was applied to observe and compare the outside characteristics of pollen,and the data were analyzed by SAS 9.1 software.Result： Some difference was found among pollen size,aperture length and the density of spine.The biggest pollen size and aperture length is Dajizhao with 61.97 μm polar axis and 61.79 μm quarter major axis and 18.03 μm aperture length,and the smallest is Honggengzi with 57.46 μm polar axis and 57.29 μm quarter major axis and 18.03 μm aperture length.Conclusion： The morphological characteristics of pollen can provide a basis for distinguishing different cultivars of L.japonica.
