不同药剂处理对早紫葡萄的扦插效应

用50 mg/L IAA 50 mg/L根旺﹑75 mg/L NAA 25 mg/L生根﹑100 mg/L生根﹑75 mg/L IBA 25 mg/L生根等药剂处理早紫葡萄插条的试验结果表明:各处理不同时期的发芽率有随着时间的推移而升高的趋势,以75 mg/L IBA 25 mg/L生根的发芽率最高(63.8%);插条生根数除50 mg/L IAA 50 mg/L根旺外,其余与对照相比均有所提高,其中以75 mg/L IBA 25 mg/L生根效果最佳.综合分析,75 mg/L IBA 25 mg/L生根在插条根长﹑根粗﹑根鲜重﹑根干重及新梢平均生长量等重要指标上均明显优于其它各处理,因此建议在生产中推广应用.

The Effect of Different Medicament on Dormant Branch Cutting of Zaozi Grape

An experiment was carried out in which cuttings of Zaozi grape were processed by some medicaments such as 50 mg/L IAA+50 mg/L Genwang?75 mg/L NAA+25 mg/L Shenggen?100 mg/L Shenggen?75 mg/L IBA+25 mg/L Shenggen.The results showed that the rate of cuttings germination processed by each drug has a rising tendency with time elapse.The germination rate of cutting processed by 75 mg/L IBA+25 mg/L Shenggen is the highest(63.8%) among all treatments.The root numbers of cutting except processed by 50 mg/L IAA+50 mg/L Genwang had some increasing tendency compared with the contrast.Among them the effect of 75 mg/L IBA+25 mg/L Shenggen is best in producing roots.By comprehensive analysis, those cuttings processed by 75 mg/L IBA+25 mg/L Shenggen is superior to that by other medicaments in root length?root thickness?weight of fresh root?weight of dried root and young shoot growth rate.It is suggested that 75 mg/L IBA+25 mg/L Shenggen should be put into practice.
