本试验于1986～1987年对山砧嫁接葡萄苗春季发根特性进行研究,结果表明:山葡萄根系发生新根首先在0.10～0.80mm粗度的细根上发生;山葡萄根系自栽植到发生新根的天数与土壤日平均温度呈极显著的负相关;0.10～0.80mm之间的根系,根皮率大都在88.00左右,而大于0.80mm者根皮率则迅速下降;光合产物向根中的输导强度往往是较细的根大于较粗的根。 In this experiment, the characteristics of the hairy roots of grapevine grafted on the hill were studied in 1986-1987. The results showed that the roots of the grapevine root first occurred on the fine root with the diameter of 0.10-0.80mm; the root system of the grape from the root to the new root There was a significant negative correlation between the number of days and the daily average soil temperature. The root bark rates between 0.10 and 0.80 mm were mostly around 88.00, whereas the root bark rates were rapidly decreased at 0.80 and 0.80 mm. The strength is often thinner roots than thicker roots.
