摘要: 以玉针香/鄂中5号/玉晶91为材料,探讨水稻(Oryza sativa L.)花药培养过程对培养效果的影响。结果表明,以蔗糖为碳源的诱导培养基诱导,低温预处理8 d效果较好,以麦芽糖为碳源的诱导培养基诱导则预处理10 d达到最好的诱导效果,但总体以麦芽糖为碳源诱导明显好于以蔗糖为碳源诱导;早取穗和晚取穗都不利于愈伤组织的诱导;以麦芽糖做碳源的诱导培养基诱导出的愈伤组织分化效果较好,分化率较高;同一批材料中,较早诱导出的愈伤组织分化率远高于后期长出的愈伤组织。

关键词: 水稻(Oryza sativa L.), 花药培养, 诱导率, 分化率

Abstract: There are many factors which influence the result of rice anther culture. In this study, Yuzhenxiang/Ezhongwuhao/Yujing91 was used to reveal the influence of rice anther culture process on culture result. Young panicles pretreated in low temperature for 8 days had a good induction rate if sucrose was added into the induction medium while pretreatment with ten days had a better result if maltose was added into the induction medium, on the whole, maltose was better than sucrose in the induction period. The time of drawing young panicles effected the induction rate and too early and too late were disadvantageous to callus induction. If calluses were induced with the medium with maltose, there would have better differentiation rate than medium with sucrose. Calluses which were induced early had much higher differentiation rate than those were lately induced.

Key words: rice (Oryza sativa L.), anther culture, induction rate, differentiation rate
