摘要:

为探究三叶青扦插快繁技术体系,本研究以浙产道地三叶青为试验材料,采用不同的激素种类(A)、激素浓度(B)、蘸根时间(C)和基质类型(D)设计了4因素个水平的正交试验,并利用灰色关联分析法,分析不同因素对三叶青扦插生根的影响。结果表明,不同激素和基质处理对三叶青扦插生根有显著(p<0.05)影响,不同处理下三叶青扦插生根率为51.76%~85.31%。在9个处理中,处理9(A3B3C2D1)的生根率最高,而处理3(A1B3C3D3)的生根率最低。相关分析表明,生根率分别与平均根数、平均根长、根鲜重和生根效果指数呈正相关,且生根率与生根效果指数相关性达到显著水平。灰色关联分析表明,关联系数最大的为处理4(A2B1C2D3),即100 mg·L-1 NAA浸泡10 min+混合基质(河沙、泥炭、珍珠岩体积比1∶1∶1)为三叶青扦插生根的最佳组合。

Abstract:

In order to explore the rapid cutting propagation technology system of Tetrastigma hemsleyanum,this study took Tetrastigma hemsleyanum from Zhejiang genuine regional drug as the test material. A four-factor,three-level orthogonal design was employed,considering different hormone types (A),hormone concentrations (B),dipping time (C),and substrate types (D). Grey correlation analysis method was used to analyze the effect of these factors on cuttage rooting of Tetrastigma hemsleyanum. The results showed that different hormone and substrate treatments had a significant (p<0.05) effect on cuttage rooting of Tetrastigma hemsleyanum. The rooting rate of Tetrastigma hemsleyanum under different treatments ranged from 51.76% to 85.31%. Among the nine treatment groups,treatment 9 (A3B3C2D1) exhibited the highest rooting rate while treatment 3 (A1B3C3D3) showed the lowest rooting rate. Correlation analysis indicated that rooting rate was positively correlated with average number of roots,average root length,root fresh weight,and rooting effect index,and the correlation between rooting rate and rooting effect index reached a significant level. Grey correlation analysis showed that the treatment with the highest correlation coefficient was treatment 4 (A2B1C2D3),which was the optimal combination of soaking 100 mg·L-1 NAA for 10 minutes and mixed substrate (river sand,peat,perlite volume ratio of 1∶1∶1) for cuttage rooting of Tetrastigma hemsleyanum.
