Asexual cutting propagation techniques of liana plant Senecio scandens

Senecio scandens is a kind of garden liana plant which has both high medical value and ornamental value. Using orthogonal experiment method by 3 levels with 4 factors,the influence of NAA concentration, cutting matrix, cuttings type and processing time on the rooting quality of S.scandens cutting propagation were studied. Cutting rooting quality included rooting rate, average root length and average root quantity. The results showed that NAA concentration had greatest impacts on the rate of rooting quality which followed by processing time, cuttings type and cutting matrix. The rooting quality of S. scandens was the best with NAA concentration 600 mg·L-1, red-yellow soil midium, stems with buds as cuttings, 1 hour processing time .
