Floral traits variation and its taxonomic value of Elaeagnus in Xinj iang
摘要
Abstract
Elaeagnus has been cultivated for a long time in Xinj iang.There are rich variations and many taxa about the species,and the taxonomy is difficult.In order to provide more evidence for solving the classification problem,a more stable form of reproductive organs as a starting point was to analyze the characteristics of floral traits variation, and select the stable traits.We analyzed the stability of stigma form,glabrous on apex of flower disc,length ratio of style to stamens,the proportion of perianth lobes to perianth fixed plant and labeled flowers.The result showed that three traits weree relatively stable:glabrous on apex of flower disc,length ratio of style to stamens,the proportion of perianth lobes to perianth,which could be used as a basis for distinguishing species;stigma form was stable in a sin-gle flower,but varied in single plant,which did not have a classification value.Finally,verification tests of floral traits proved the correctness of the above conclusions,but also was the classification of the genus practical applica-tion,providing the basis data for the study of classic reference taxonomy,morphology,the development and protec-tion in Elaeagnus.关键词
