栽培金银花非腺毛性状特征研究

Study on characteristics of non-glandular hairs of cultivated Lonicera japonica

采集17个地区22个金银花栽培居群,通过扫描电子显微镜观察和测量花蕾非腺毛的性状特征,利用长度和密度的数据对22个栽培居群进行PCA主成分分析和相关性分析,找出不同产地金银花非腺毛的差异和相关性。结果表明,花蕾非腺毛长度与密度具显著负相关关系,非腺毛密度可将鸡爪花系与毛花系分开,而花蕾非腺毛长度和密度与产地的经纬度没有显著相关性,其中的3个离群居群产生了明显的变异分化可能与气候和土壤的差异有关,暗示栽培金银花花蕾非腺毛的性状特征受环境和遗传共同影响。以上结果为金银花栽培种质和产地鉴别提供了依据。

We collected 22 cultivated population of Lonicera japonica from 17 areas. The characteristics of non-glandular hairs were observed and measured by the scanning electron microscopy. The principal components analysis and correlation analysis were conduct based on length and density of L. japonica. The results showed a significant negative correlation between length and density of non- glandular hairs, and the characteristics of non-glandular was not corrrelated significantly with latitude. The correlation results indicated that the density was a key to separate ＂Damaohua＂ and ＂Jizhuahua＂. The contribution of climate and soil was important to the cultivated population. This reminded that the characteristics of non-glandular hairs were affected by environmental and genetic interaction.
