摘要:
以苏杨7号1年生枝条为材料,对影响生根的因素进行了试验研究。结果表明:基质种类对扦插生根率和生根效果指数均有极显著影响,植物生长调节剂种类、处理时间和穗条部位对生根效果指数有显著性影响,植物生长调节剂质量浓度影响均不显著。对生根率的影响由大到小依次为基质种类>植物生长调节剂种类>植物生长调节剂质量浓度>穗条部位>处理时间,对生根效果指数的影响由大到小依次为植物生长调节剂种类>基质种类>处理时间>穗条部位>植物生长调节剂质量浓度。以壤土为基质,用200 mg/L的萘乙酸处理1 h的外部枝条,可获得最大生根效果。
Abstract:
The factors which could affect the rooting of cuttage from annual branches of Populus deltoides March.‘SuYang7’ were systematically studied.The results showed that different substrates had a highly significant effect on the rooting rate and index of root system. Different hormone-like chemicals, treating time and branch positions from which the cuttage was got could affect index of root system significantly. Only hormone-like chemical concentration had no significant difference on either index. Sorted by effect on rooting rate, such a descending order was got as substrate,hormone-like chemical,chemical concentration,branch position from which the cuttage was got,and treating time. Sorted by effect on index of root system, such a descending order was got as hormone-like chemical, substrate, treating time, branch position, and chemical concentration. The upper branche soaked in 200 mg/L NAA for one hour could get the maximum rooting benefits with the garden soil as substrate.
