摘要: 试验以天津市葛沽萝卜子叶、子叶柄和下胚轴为外植体诱导松散型愈伤组织,探究不同外植体和不同激素浓度对其松散型愈伤组织诱导的影响。结果表明,不同外植体均能诱导出愈伤组织,只有子叶和子叶柄能诱导获得松散型愈伤组织。子叶诱导的松散型愈伤组织生长较快,愈伤组织诱导率为(26.88±1.44)%,子叶是诱导松散型愈伤组织的最适外植体。葛沽萝卜松散型愈伤组织诱导最佳培养基为MS+0.25 mg/L 6-BA+2.0 mg/L 2,4-D,松散型愈伤组织诱导率为(95.83±2.20) %,且褐化率仅(0.83±0.83)%。

Abstract: In this study, leaf, petiole and hypocotyl of Gegu radish were used as explants to induce loose callus,to explore the effect of different explants and different hormone concentrations on the induction of loose callus. The results showed that different explants all could induce callus, but only cotyledon and petiole could induce loose callus, and the loose callus induced by cotyledon grew faster, and the callus induction rate was(26.88±1.44)%. Cotyledon was the most suitable explant for inducing loose callus. The optimal medium for induction of loose callus was MS+0.25 mg/L6-BA+2.0 mg/L 2,4-D. The induction rate of loose callus was(95.83±2.20)%, and the browning rate was only(0.83±0.83)%.

Key words: Gegu radish, cotyledon, friable callus
