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。
Twenty-two honeysuckle cultivars were collected from 17 areas. The morphological characteristics of non-glandular hairy buds were observed and measured by scanning electron microscopy. PCA principal component analysis and correlation analysis were conducted on 22 cultivated populations using length and density data to find out Differences and correlations of non-glandular hairs among honeysuckle in different habitats. The results showed that there was a significant negative correlation between the length and density of non-glandular trichomes in flower buds. The non-glandular hair density could separate the chicken claw flower from the gerbera flower. However, the length and density of non-glandular trichomes had no significant correlation with the latitude and longitude of origin Of the three populations had obvious variation and differentiation may be related to climate and soil differences, suggesting that the traits of non-glandular buds cultivated honeysuckle flower traits by environmental and genetic together. The above results provide the basis for the identification of honeysuckle cultivars and their origin.
