植物激素配比对大蒜茎盘愈伤组织再生体系的影响

植物激素对大蒜茎盘愈伤组织再生的各个环节都发挥着重要的作用。试验结果表明：2,4．D对茎盘愈伤组织的诱导具有主要作用，高浓度的2，4-D有利于大蒜愈伤组织的诱导，但并不利于其增殖分化。MS＋NAA 2mg／L＋BA 1mg／L培养基适宜于愈伤组织的继代增殖，MS＋NAA 1mg／L＋BA 5mg／L培养基适宜不定芽的分化，只添加NAA或无激素的MS培养基有利于不定芽生根。

Effect of Plant Growth Regulators Combination to the Stem Disc Callus Regeneration System of Garlic (Allium sativum L.)

Plant growth regulators play an important role in the processes of plantlet regeneration from the stem disc calli of garlic.Experimental data suggests that 2,4-D is most important to stem disc callus induction.(2,4-D) at high concentration is favorable to the callus induction,while it is unfavorable to callus propagation and differentiation.MS NAA 2 mg/L BA 1 mg/L and MS NAA 1 mg/L BA 5 mg/L medium is suitable for culli subculture and adventitious shoots differentiation respectively,while medium supplemented with NAA only or no hormone is favorable for root differentiation.
