【摘要】 采用常规根尖压片法对黄麻属(Corohorius)5个野生种及其2个栽培种的染色体数目和核型进行研究。结果表明:染色体数目均为2n=14。核型公式分别为:宽叶长果C.olitorius(黄麻长果栽培种)2n=2x=14=14m(4SAT);南阳野生长果C.olitorius(黄麻长果野生种)2n=2x=14=14m(2SAT);坦桑尼亚野生长果C.olitorius(黄麻长果野生种)2n=2x=14=2M+12m;闽麻5号C.capsularis(黄麻圆果栽培种)2n=2x=14=12m+2sm;爱店野生圆果C.capsularis(黄麻圆果野生种)2n=2x=14=14m;廉江野生圆果C.capsularis(黄麻圆果野生种)2n=2x=14=4M+10m;假黄麻C.aestuans(黄麻属野生种)2n=2x=14=2M+12m;假长果C.pseudoolitoius(黄麻属野生种)2n=2x=14=2M+12m;甜麻(未定名,黄麻属野生种)2n=2x=14=14m。其中除了宽叶长果核型分类为1B外,其他的都为1A型。本文还讨论了黄麻野生种甜麻的分类学地位。更多还原

【Abstract】 The chromosome number and karyotype of five wild species and two cultivated species of Corohorius were studied by applying root tip squash method.The result showed that the chromosome number was 2n=14,the karyotype formulas were as follows:kuanye long-capsule cultivars of jute(Colitorius) 2n=2x = 14 = 14m(4SAT); Nanyang long-capsule wild species of jute(Colitorius) 2n=2x=14 = 14m(2SAT);Tanzania long-capsule wild species of jute(C.olitorius) 2n=2x=14=2M+12m;Min ma No.5(C.capsularis) 2n=2x=14=12m+2sm;Aidian boll wild species of jute(C.capsularis) 2n=2x=14=14m;Lianjiang boll wild species of jute(C.capsularis) 2n=2x=14= 4M+10m;C.aestuans 2n=2x=14=2M+12m;C.pseudo-olitorius 2n=2x=14=2M+12m;Tianma(unnamed) 2n=2x=14= 14m.All of the karyotypes belong to 1A type except kuanye long-capsule cultivars of jute(Colitorius) is 1B type.The taxonamic status of Tianma(wild species of jute) was also discussed in the research.更多还原
