| 摘 要： | 通过人工诱导烟草结瘤的方法,观察给予2,4-D、根瘤菌后,其对烟草根尖细胞有丝分裂和染色体畸变的影响.结果表明:在Jensen无氮营养液中,不论是只加2,4-D、根瘤菌,还是既有2,4-D又有根瘤菌,烟草根尖细胞有丝分裂指数在处理前期均有增加,其中以2,4-D和根瘤菌共同处理表现最为显著;但在处理的后期,细胞有丝分裂活动受到明显地抑制,并且伴有不同程度地染色体畸变.

| Abstract: | Effects on mitosis and chromosomal aberrations of tobacco root tip cells were observed by the method of artificially inducing para-nodule treated with 2,4-D and rhizobium.The results indicated that all treatments could increase remarkably mitotic index at early time within Jensen non-nitrogen medium,especially the treatment with both 2,4-D and rhizobium.But activities of cell division were inhibited significantly at terminal time after different treatments,companied with chromosomal aberrations in different degrees. |
