基质与激素对茵芋扦插成活率效应研究
Effect of matrix and hormones on the cutting survival rate of Skimmia reevesiana Fort.
摘要
Abstract
This study was designed to investigate the cutting survival rate of Skimmia reevesiana Fort.under different matrix,different hormones and hormone concentrations,to filter out the best combination of matrix,hormones and hormone concentrations,and to provide a theoretical basis for Skimmia reevesiana Fort.in domestication and industrialization development.The three-factor factorial design of 16 matrix types,5 hormone types and hormone concentrations were used to study the cutting survival rate of Skimmia reevesiana Fort.under the various factors and the interaction of various factors.The results showed that the effects of different matrix,hormones and their concentration on improving cutting survival rate were significant,matrix effects on the survival rate was the biggest,then followed by hormones,hormone concentration was relatively small.Among 16 kinds of matrix type,the cutting survival rate of mixed matrix that 30％ perlite + 40％ peat + 30％ river sand was the best,among the hormone types,effects on the cutting survival rate of Skimmia reevesiana Fort.were IAA ＞ IAA +NAA ＞ IBA + NAA ＞ IBA ＞ NAA,the effect of IBA + NAA and IAA + NAA mixed hormone combination was not significant.Among the hormone concentrations,the difference of IBA + different concentrations of NAA,IBA,NAA was significant or very significant,concentration effect was that the survival rate would be reduced if concentration raised,the differences of IAA + NAA and IAA were not significant between different concentration levels;But the cutting survival rate of water was the highest,with an average survival rate of 89.84％,the organs had a strong endogenous hormones forming ability after mechanical damage.The best cutting propagation measure was soaking cuttings with water and using mixed matrix of perlite + peat + river sand (3 ∶ 4∶ 3);The second best measure was using mixed matrix of perlite + peat + river sand(3∶ 4∶3),with the implementation that 400 mg/L of IAA;the measure that sand matrix with the implementation of 400 mg/L IAA was economical and practical.关键词
