- 摘要:
- 以紫丁香嫩枝为试材，研究了生长调节剂、插穗粗度及不同部位插穗对紫丁香嫩枝扦插生根的影响。结果表明：紫丁香嫩枝扦插受生长调节剂种类及浓度的影响，1 500 mg?L-1 IBA处理效果最佳，生根率达到了89.25%，显著高于其它组合。不同粗度插穗生根率差异显著，以细插穗（0.4～0.5 cm）生根效果较佳，生根率达到88.14%，插穗粗度对一级根条数、一级根长影响不显著。不同部位插穗对紫丁香生根特性有明显影响，中部插穗生根效果最好，生根率、一级根长及一级根数都显著高于上部和下部，其值分别为87.71%、6.00 cm和15.59条。
- 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.
