摘要:
以多肉植物‘特玉莲’叶片为试材，采用鳞片扦插的方法，研究了扦插基质的种类、配比和生长调节剂的种类、浓度对芽诱导及植株缀化的影响，以期探索‘特玉莲’芽诱导和缀化的最佳条件，为多肉植物规模化繁育高质量的幼苗提供参考依据。结果表明：蛭石为诱导芽和新头的最佳培养基，扦插90 d时每个叶片诱导的芽和新头分别为2.4个和2.0个，其成活率高达100%；KT和2,4-D对芽、新头和叶片的诱导没有促进作用，NAA、6-BA、IBA、IAA和GA3均能促进三者的诱导，其中20 mg?L-1 NAA浸泡20 min为最佳处理方式，每片叶诱导的芽、新头和叶片分别达到4.8个、3.2个和36.8片；诱导缀化最佳的生长调节剂组合为80 mg?L-1 NAA+800 mg?L-1 6-BA等体积混合溶液。
Abstract:
The leaves of succulent Echeveria runyonii ‘Topsy Turvy’ were used as materials,the scale cutting method was used,the effects of the different type cutting media proportion and different growth regulators concentration on bud induction and embellishment by scale cutting were studied,in order to explore the optimal conditions for bud induction and embellishment of Echeveria runyonii ‘Topsy Turvy’ and provide a reference for the large-scale breeding of high-quality seedlings of succulent plants.The results showed that vermiculite was the best medium for inducing buds and new heads,the induced buds and new heads of each leaf were 2.4 and 2.0 respectively 90 days later,and the survival rate was as high as 100%;KT and 2,4-D did not promote the induction of buds,branches and leaves,but NAA,6-BA,IBA,IAA and GA3 could do them;20 mg?L-1 NAA soaking for 20 minutes was the best treatment,which induced 4.8,3.2 and 36.8 buds,new heads and leaves respectively;the best combination of growth regulators for induced patching was 80 mg?L-1 NAA+800 mg?L-1 6-BA mixed solution.
