Abstract
A karyological study using the Image Analysis System was conducted of eight taxa of the genus Medicago L. namely M. radiata L., M. intertexta (L.) Mill. M. orbicularis (L.) Bart. , M. laciniata (L.) Mill., M. coronate (L.) bartal, M. rigidula (L.) All., M. polymorpha L.and M. scutellata (L.) Mill. used as forage plants from different geographic origins of Fars province from Iran. We found the two usual basic chromosome numbers in the genus, x=7 and x=8. In the group with x=7, two diploid (2n=14), one tetraploid (2n=28) species and in the group with x=8, five diploid (2n=16) species were found. Detailed karyotype analysis allows us to group the different species and to postulate relationships among them.
利用图像分析系统对紫花苜蓿属8个分类群(M. radiata L.， M. intertexta (L.))进行了核生物学研究。轧机。圆轮虫(L.)Bart. M. laciniata (L.)轧机。M. coronate (L.) bartal, M. rigidula (L.)所有人。、多花田葵、花田葵轧机。用作饲料的植物，来自伊朗法尔斯省的不同地理来源。我们发现了两种常见的基本染色体数，x=7和x=8。x=7组有2个二倍体(2n=14)种，1个四倍体(2n=28)种，x=8组有5个二倍体(2n=16)种。详细的核型分析使我们能够对不同的物种进行分类，并推测它们之间的关系。
