大蒜花苞具有很强的不定芽增生潜力,是不定芽体系快繁的理想外植体。在MS+NAA1 mg/L+KT5 mg/L培养基上,早苔2号蒜花苞的繁殖系数为19.2,晚熟品种的繁殖系数更高。低温能促进试管鳞茎的发生,花苞4℃预处理10d后,82.9%的不定芽都形成试管鳞茎。由大蒜花苞诱导不定芽的发生,然后诱导试管鳞茎的形成,这是一种适于大蒜快繁的新型再生体系。 Garlic buds have strong potential for adventitious buds proliferation and are ideal explants for rapid propagation of adventitious buds. On the MS + NAA1 mg / L + KT5 mg / L medium, the propagation coefficient of the early bud No.2 garlic bud was 19.2, and that of the late maturing cultivar was higher. Low temperature can promote the occurrence of test tube bulbs, bud 4 ℃ after pretreatment 10d, 82.9% of adventitious buds formed test tube bulbs. Induction of adventitious buds by garlic buds induces the formation of test tube bulbs, a new regeneration system suitable for the propagation of garlic.
