Aronia melanocarpa elliot rooting by softwood cutting method

The invention discloses an aronia melanocarpa elliot rooting by softwood cutting method. Aronia melanocarpa elliot serves as a test material, through the influence of different exogenous hormone concentrations on the rooting by softwood cutting effect, the cuttage effect of each treatment combination is evaluated comprehensively based on the principal composition analysis method. The result showsthat the variation degrees of rooting traits of cuttings treated with different concentrations of exogenous hormones are very large, wherein the variation degrees of the branch number, the primary root number, the secondary root number and the root length are very large and up to 70% or above. Through factorial analysis, two main components are extracted, the characteristic roots of the main components are larger than 1, and the cumulative variance contribution rate is 89.109%. According to the comprehensive score, after treatment with 500 mg L-1 ABT1, the comprehensive score is highest and the root systems of the cut
