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.
