摘要: 以中间锦鸡儿茎段为外植体,建立了它的组织培养体系,具体条件如下:愈伤组织诱导培养基为MS+GA3 0.15 mg/L+6-BA 0.2 mg/L+NAA 0.4 mg/L+AC 0.1 g/L+蔗糖25 g/L+琼脂6 g/L,愈伤诱导率达33.33%;丛生芽诱导培养基为MS+6-BA 1.0 mg/L+NAA 0.2 mg/L +蔗糖25 g/L+琼脂6 g/L,诱导率为13.33%;诱导生根培养基为MS+IAA 0. 5 mg/L+GA3 0.15 mg/L +蔗糖20 g/L+琼脂6 g/L,生根率达60%;将生根幼苗移至蛭石和营养土体积比为2∶1的基质中,移栽成活率高达100%.

Abstract: The study established the tissue culture system with the stem segment of Caragana intermedia as the explant, and the results were as follows: with the callus induction medium of MS + GA3 0.15 mg/L + 6-BA 0.2 mg/L + NAA 0.4 mg/L + AC 0.1 g/L + sucrose 25 g/L + agar 6 g/L, callus induction rate was 33.33%;With the induction medium of MS + 6-BA 1.0 mg/L + NAA 0.2 mg/L + sucrose 25 g/L + agar 6 g/L, sheath bud induction rate was 13.33%; With rooting medium of MS + IAA 0.5 mg/L + GA3 0.15 mg/L + sucrose 20 g/L + agar 6 g/L, rooting rate of 60%; After rooting, the rooting seedlings were moved to a substrate with vermiculite and nutrient soil with volume ratio of 2∶1 and the survival rate was 100%.
