| 摘 要： | 对生长在同一生境的中国沙棘、蒙古沙棘和俄罗斯沙棘的核型进行了比较研究.结果表明:3种沙棘的染色体数目均为2n=24,都由中部着丝粒染色体组成.其中,中国沙棘、蒙古沙棘在第4对染色体上有随体,俄罗斯沙棘在第2对染色体上有随体.3种沙棘的核型类型都是2A型,比较对称.

| Abstract: | The karyotypes of China seabuckthorn,Russia seabuckthorn and Mongolia seabuckthorn were analysed in this study.The results showed that three seabuckthorn all have 24 chromosomes and all are diploid,metacentric chromosome.China seabuckthorn and Mongolia seabuckthorn have satellites at 4th chromosome,Russia seabuckthorn at 2nd chromosome.The karyotype are all 2A and symmetrical. |
