Effects of Different Treatments on Cuttings Rooting of Sorbus Koehneana Schneid
lignified and semi-lignified cuttings of Sorbus koehneana Schneid were used as material,the effects of growth regulator type,concentration,soaking time and number of leaves on rooting effect of S.koeh-neana Schneid were studied by single factor test and orthogonal test.The results showed that callus was the main root of hard branch cuttings,and the best rooting effect was 200 mg/L IAA treatment.The type of growth regulator was the main factor affecting the rooting of the cuttings,followed by the concentration,soaking time and the number of leaves.The results of range analysis showed that treatment 6(A2B3C1D2)was the optimal combination,and the rooting effect was the best.This experiment found out the suitable rooting combination of S.koehneana Schneid,and provided reference for its cutting seedling production.
