摘要
用ABT、GGR生根粉和NAA不同浓度处理葡萄插条,比较其对葡萄插条生根的影响。结果表明,上述三种激素均可促进葡萄插条生根,提高生根率,促进根系生长。其中ABT与GGR生根粉促进插条生根的最适浓度均为50～70mg/L;NAA促进生根的最适浓度为30～50mg/L。综合插条素质看,以50mg/LABT生根粉处理的生根效果最好。
Vitis vinifera L.cuttings were treated bydifferent dosages ABT、GGR root growth powder and NAA.The propose was to test the effects of three kinds of growth regulators on root growth of cuttings.The result indicated that the above regulators all promoted root growth and root growth rate of cuttings as well root system growth.Among them,the optimum concentration of cuttings root growth by use of ABT、GGR powder all was50～70mg /L and the adaptive dosage by use of NAA was30～50mg /L.Either way,the effect of cuttings root growth treated by ABT50mg /L was the best.
