| 摘 要： | 为给木槿的资源开发及遗传改良工作提供依据,本研究对13个家系木槿的繁殖特性、生长特性和开花特性进行了研究。结果发现:不同家系种子千粒重、发芽率以及家系子代扦插生根率、生根数、株高、基径、开花株率方面均存在显著差异,进行家系选择有效。开花株率与基径间,生根率与基径间以及生根率与发芽率之间呈明显正相关,其他性状之间相关性不明显。对发芽率进行家系选择其效果优于对千粒重、发芽势和扦插生根率的家系选择;对扦插生根率进行单株选择的效果优于家系选择;无论是家系选择还是单株选择,对株高的选择效果均优于对基径的选择;无论是株高还是基径,单株选择的效果都优于家系选择。通过多指标聚类分析,将7个家系分成3类,并分类描述了各类家系的生殖、生长能力。

| Abstract: | In order to provide a basis for genetic improvement and resource development of Hibiscus syriacus,propagation,growth and flowering characteristics of 13 families were analyzed in the paper.The result indicated that there were significant differences in 1 000-seed weight and germination rate among families.Rooting rate,rooting number,stem height,base diameter and blossoming rate were also significantly different.So,family selection will get positive results.There was significant positive correlation between ... |
