Effects of Different Treatment Methods on Cutting Propagation of Rosa multiflora
Rosa multiflora was used as material,the effects of IBA concentration,covering film time and cutting substrate on the effect of Rosa multiflora were studied with orthogonal design L9(34),so as to improve the breeding technology system of Rosa multiflora.The results showed that the best level combination of survival rate was the loess+covering film 30days+IBA 100mg·L-1;the best level combination of sprouting rate was peat mixed perlite+covering film 15days+IBA 50mg·L-1; the best level combination of average sprout height was loess+covering film 15days+IBA 200mg·L-1; the best level combination of average number of leaflet was loess+covering film 30days+IBA 50mg·L-1;the best level combination of average number of root was loess+covering film 15days+ IBA 50mg·L-1.
