| 摘 要： | 采用去壁低渗法研究了两种辣椒的核型。结果表明,小米辣椒Capsicum.frutescens Linn.为2n=24=22m+2Sm(SAT),属2A 型核型;樱桃辣椒c.annuum var.cerasiforme Irish 为2n=24=20m+2sm(SAT)+2st,属2B 型核型。本文还讨论了小米辣椒和辣椒核型的进化问题。

| Abstract: | Wall degradation hypotonic treatment and flame-drying method were adopted tostudy the karyotypes of 2 taxa of Capsicum.The karyotype formula of C.frutescens turnedout to be 2n=24=22m+2sm(SAT),while that of C.annuum var.cerasiforme was expressedas 2n=24=20m+2sm(SAT)+2st.The karyotype asymmetry demonstrates thatC.frutescens is of 24 type and C.annuum var.cerasiforme of 2B type.Karyotype evolutionin C.annuum and C.frutescens is discussed. |
