Abstract:
Taking twig of Syringa oblata Lindl as test material,the effects of growth regulator,the roughness of cuttings and different parts of the cuttings on rooting were studied.The results showed that the lilacs twig cuttings were influenced by types and concentration of growth regulators,1 500 mg?L-1 IBA had the best treatment effect,rooting rate reached 88.14%,significantly higher than other combination.Rooting rate was significant difference in different roughness cuttings,fine cuttings(0.4-0.5 cm)rooting had effect better,rooting rate reached 88.14%,but the roughness of cuttings impact on first-class article root number,root length were not significant.Different parts of the cuttings root characteristics had obvious influence of lilacs,central cuttings rooting effect was the best,rooting rate,level of root length and root number were significantly higher than that of the upper and lower,the values were 87.71%,6.00 cm and 15.59 bars,respectively.
