紫藤三叶青茎扦插育苗方法探索

Method of Stem Cutting Seedling of Tetrastigma hemsleyanum

  • 摘要: 为促进紫藤三叶青快速扦插育苗,采用裂区设计法对影响三叶青扦插成活的插条茎节数、遮阳率等进行研究,比较分析不同处理下三叶青扦插的存活率、新梢长、小叶数、生根数量、块根数等指标,探究紫藤三叶青高效简单的扦插繁殖方法。结果表明,新梢长、小叶数与存活率的相关系数分别为0.824 0和0.774 5;插条两个茎节(A2)、遮阳60%(B2)的情况下,存活率(91.33%)、新梢长(16.11 cm)、小叶数(4.3)等性状值均高于其他情况。说明在紫藤三叶青扦插育苗过程中,插条带2个茎节,并做60%的遮阳处理,效果最佳。

     

    Abstract: In order to promote rapid cutting seeding of Tetrastigma hemsleyanum.The split plot experiment method was used to study the number of stem nodes and shading rate of cuttings for Tetrastigma hemsleyanum.The survival rate,length of new shoots,number of leaflets and number of roots for Tetrastigma hemsleyanum under different treatments were compared and analyzed.The results showed that the correlation coefficients between length of new shoots,number of leaflets and survival rate were 0.824 0 and 0.774 5,respectively.Two stem nodes(A2)and 60% shading(B2),the survival rate(91.33%),new shoots length (16.11cm)and number of leaflets(4.3)were higher than other combinations.It is believed that the cuttings should have two stem nodes and 60% shading treatment in the process of trial have the best results.
