君子兰(Clivia miniata Regel)原产于非洲南部的纳塔尔一带森林中。又名剑叶兰(或大花君子兰),为石蒜科(Amaryllidaceae)多年生草本植物。鉴于我国栽培普遍,特别是近年,经杂交、栽培陆续选育出许多具有优良性状的新品种,使其观赏价值大为提高,并在观赏花卉中愈来愈享有较高的盛誉。但目前关于君子兰的基础研究,特别是细胞遗传学方面的研究,还很缺乏。为了给君子兰的育种工作提供基础资料,我们对它的染色体组型作了初步研究。 材料与方法 Clivia miniata Regel is native to the forests of Natal in southern Africa. Also known as Jian Yelan (or Dahua Clivia), amaryllidaceae (Amaryllidaceae) perennial herb. In view of the common cultivation in our country, especially in recent years, many new varieties with excellent traits have been bred by crossing and cultivating in succession so as to greatly enhance their ornamental value and enjoy more and more high reputation in ornamental flowers. However, there is still a lack of basic research on Clivia, especially in cytogenetics. In order to provide the basic information for the breeding of Clivia, we conducted a preliminary study on its chromosome constitution. Materials and Methods
