A comparison of morphology, karyotype and the chemical compounds among
“Jinxiong”, Ligasticum chuanxiong Hort. and L. chuanxiong cv. Fuxiong shows that “Jin-
xiong”, like L. chuanxiong cv. Fuxiong, is a triploid and its karyotype is similar to that of
L. chuanxiong with the formula K(2n)=33=24m+6sm+3st(SAT). Thin-layer chromato-
graphy of essential oils extracted from stem tubers confirms that the three taxa are extremely
alike in chemical compounds. Using the features of leaves and the forms of stem tubers, they
can be easily distinguished. A new triploid cultivar of L. chuanxiong Hort. i.e.L. chuan-xiong cv. Jinxiong is described for “Jinxiong” in the present paper. 相似文献

采用0．1％秋水仙素溶液、0．002mol／L的8-羟基喹啉溶液、对二氯苯饱和溶液、0．1％秋水仙素溶液和0．002mol／L的8-羟基喹啉溶液混合液（V：V=1：1）、0．1％秋水仙素溶液和对二氯苯饱和溶液混合处理液（V：V=1：1）对大豆根尖进行处理,以蒸馏水处理作为对照．结果表明：各种预处理方法有丝分裂指数均比对照有所提高,分别提高了0．43％、0．41％、4．45％、1．07％、0．83％,其中提高最明显的是用对二氯苯处理的．通过方差分析和多重比较可以看出,对二氯苯处理的与其他各预处理方法的差异达极显著． 相似文献
