将不同浓度的茉莉酸甲酯(MeJA) 或水杨酸(SA) 添加于B5 培养基中, 研究其对离体条件下大蒜鳞茎的诱导及膨大作用。结果表明: MeJA 诱导鳞茎形成和促进鳞茎膨大的最佳浓度均为2×10- 6 mol/L, 诱导率高达97% , 鳞茎鲜重可达100 mg。SA诱导鳞茎形成的最佳浓度为5 ×10- 5 mol/L, 诱导率可达94 % ; 促进鳞茎膨大的最佳浓度为5 ×10 - 4 mol/L, 鳞茎鲜重可达165 mg。表明MeJA 和SA在大蒜鳞茎形成中具有重要的调控作用。 Different concentrations of methyl jasmonate (MeJA) or salicylic acid (SA) were added to B5 medium to study the induction and expansion of garlic bulb under in vitro conditions. The results showed that the optimal concentration of MeJA to induce bulb formation and bulblet enlargement was 2 × 10-6 mol / L, the induction rate was as high as 97%, and the fresh weight of bulb was up to 100 mg. The optimal concentration of SA to induce bulb formation was 5 × 10-5 mol / L and the induction rate was 94%. The optimal concentration of bulblets to promote bulblets was 5 × 10 -4 mol / L and the fresh weight of bulbs reached 165 mg. Show that Me  JA and SA in garlic bulb formation has an important regulatory role.
