应用根尖压片法研究了2种吊兰的染色体数目、核型.结果表明:金边吊兰(C.comosum variegatum Hort)体细胞中期兰的染色体核型:2n=2x=28=8m+10sm(1SAT)+10st,不对称系数AS.K% =69.4%.染色体相对长度组成为2n=2x=28=2L+4M2+6M1+2S,属3A型.金心吊兰(C.comosum Medio-pictum Hort)体细胞中期兰的染色体核型: 2n=2x=28=4 m+18 sm+6 st,不对称系数AS.K%=68.1%.染色体相对长度组成为2n=2x=28=2L+5M2+5M1+2S,属3B型.
應用根尖壓片法研究瞭2種弔蘭的染色體數目、覈型.結果錶明:金邊弔蘭(C.comosum variegatum Hort)體細胞中期蘭的染色體覈型:2n=2x=28=8m+10sm(1SAT)+10st,不對稱繫數AS.K% =69.4%.染色體相對長度組成為2n=2x=28=2L+4M2+6M1+2S,屬3A型.金心弔蘭(C.comosum Medio-pictum Hort)體細胞中期蘭的染色體覈型: 2n=2x=28=4 m+18 sm+6 st,不對稱繫數AS.K%=68.1%.染色體相對長度組成為2n=2x=28=2L+5M2+5M1+2S,屬3B型.
