杨德奎;   
山东师范大学生物系
摘要:
本文对山东4种草本植物进行了染色体研究。结果表明:阿尔泰狗哇花(Heteropappusal taicus(Wild)Navopokr)的染色体数目为2n=36,核型公式为K(2n)=36=36m,核型“1A”型;求米草(Oplismenusundulatifolius(Arduino)RoemetSchult)的染色体数目为2n=12,核型公式为K(2n)=12=8m+4sm,核型“2A”型;红秋葵(Hibiscuscocineus(Medic)Walt)的染色体数目为2n=38,核型公式为K(2n)=38=14m+22sm+2st,核型“2B”型;蟋蟀草(Eleusineindica(L)Gaertn)的染色体数目为2n=18,核型公式为k(2n)=18=16m+2sm,核型“2A”型。
