Influence of Substrate and IBA Concentration on Hard Branch Cuttings of Table Grape'Tiangongmoyu'
In order to promote the breeding and promotion of table grape varieties,in this study,the effects of different substrates+different concentrations of IBA on the cuttings of table grape'Tiangongmoyu'were studied.The results showed that with the increase of IBA concentration,the rooting rate of'Tiangongmoyu'hard branch cuttings gradually increases.Under the same IBA concentration,perlite was used as the cutting medium,and the rooting rate of'Tiangongmoyu'was the highest.Using elastic medium as cutting medium,'Tiangongmoyu'hard branch cutting had the lowest rooting rate.When the concentrations of IBA were 750 and 1 000 mg·L-1 there was no significant difference in the number of hard cuttings of'Tiangongmoyu'under the same medium condition.Leaf number,root fresh weight,root dry weight,leaf fresh weight,leaf dry weight and other indexes of'Tiangongmoyu'were evaluated comprehensively,the perlite was used as cutting medium and 750 mg·L-1IBA was used as hormone.
