| 摘 要： | 辣椒是二倍体植物(2n=24),本实验用秋水仙素水溶液处理辣椒种子和幼苗,获得了四倍体(2n=48).实验表明:四倍体辣椒的叶、茎、花、果和种子等各个器官均表现了肥大特征,但四倍体现蕾比二倍体晚5—7d.用四倍体做母本,二倍体做父本,进行杂交,获得了同源三倍体(2n=36).子叶的宽长比值可作为多倍体鉴定的指标.

| Abstract: | Bush redpepper Capsicum annuum L. is a diploid,2n = 24. The tetraploid ( in - 48 ) form has been obtained by treating the Bush redpepper seeds and seedlings with aqueous solutions of colchicine. The results show: some organs of tetraploid, such as leaf, stein flower, fruit and seed etc., have exhibited hyperplasia, but the floral initiation of tetraploids is 5-7 days later than that of diploids. The autotriploid ( 3n=36 ) form has been got by hybridizing the diploid ( parent) with tetraploid ( parent). The breadth-length rate of cotyledon can be used to identify polyploid plants. |
