使用EMS处理由水稻成熟胚诱导的愈伤组织,观察了愈伤组织生长、细胞染色体畸变和植株分化情况。试验结果表明,低浓度EMS处理对水稻愈伤组织生长和植株分化有刺激作用,较高浓度EMS处理则有抑制作用。
The callus induced from mature rice embryos was treated with EMS and the callus growth, chromosomal aberrations and plant differentiation were observed. The results showed that low concentrations of EMS treatment on rice callus growth and plant differentiation stimulated, the higher the concentration of EMS treatment is inhibited.
