摘要：

对18种豆科树种的染色体计数结果表明,豆科树种的染色体数目与其结瘤之间存在一定的关系。不结瘤的10种树种除望江南染色体数是26条外,其余9种树种的染色体数目都为2n=2x=28,都能被7整除,其中包括苏木亚科的槐叶决明、伞房决明、双荚决明、毛决明、黄槐决明、铁刀木、任豆、皂荚和蝶形花亚科中的国槐;而结瘤的8种树种,其中含羞草亚科的合欢、银荆、肯氏相思、马占相思,它们的染色体数目均为2n=2x=26;蝶形花亚科的马蹄针为2n=2x=18,紫穗槐为2n=2x=40,刺槐、木豆均为2n=2x=22,它们的染色体数目都不是7的倍数。

Abstract:

According to the counting the chromosome numbers of 18 species of leguminous trees(Leguminosae), the chromosome numbers have relationship with nodulation in some degree in the leguminous trees.The chromosome numbers of 10 species of leguminous trees which are not nodulade in the field except for Cassia occidentalis are all 28 and can be divided integrally by 7. These trees are Cassia sophera, C. canymbosa, C. bicapsularis, C. hirsnta, C. suffruticosa, C. siamea, Zenia insignis, Gleditsia sinensis in Caesalpinioideae and Sophora japonica in Papilionoideae. The chromosome numbers of C. occidentalis which is in Caesalpinioideae is 26. Each of the chromosome number of 8 species of leguminous trees which can be nodulated is not 28. These 8 species of leguminous trees which can be nodulated are as follow: chromosome numbers of Albizia julibrissin, Acacia dealbata, Acacia cunnihami and Acacia mangium in Mimosoideae are all 26, chromosome numbers of Sophora davidii in Papilionoideae is 18, chromosome numbers of Amorpha fruticosa in Papilionoideae is 40, and chromosome numbers of Robinia pseudoacacia and Cajanus cajan in Papilionoideae are 22. These chromosome numbers all are not divided integrally by 7.
