贴梗海棠(Chaenomeles speciosa)又名皱皮木瓜,属蔷薇科木瓜属。其花朵硕大,花色猩红,簇生于二年生枝上,先于叶开放,具较高的观赏价值。但国内外尚未见有此树种茎段离体培养的报道。本文试图从快速繁殖的角度探讨不同激素对贴梗海棠芽的增殖、生长及生根过程的影响,为木本花卉植物的快速繁殖提供参考。材料用生长季旺长的嫩梢,切成带1—2个侧芽的茎段作外植体。以MS为基本培养基 Chaxingomei (Chaenomeles speciosa), also known as wrinkled papaya, belongs to Rosaceae Papaya. Its huge flower, scarlet color, clustered in biennial branches, open before the leaves, with a high ornamental value. However, at home and abroad have not yet seen this tree species in vitro culture reports. This article attempts to explore the effects of different hormones on the proliferation, growth and rooting of stalk begonia buds from the perspective of rapid propagation, and provide a reference for the rapid propagation of woody flower plants. Materials with growing season Wang long young shoots, cut with 1-2 lateral bud stem section as explants. MS as the basic medium
