引言:沙梨(Pyrus pyrifolia L.)是印度 Himachal prades 低山丘陵地区最成功的栽培种,产量高,不需要精细管理。通常人们都认为这个栽培种很难扦插生根,急需研究出能用于大田生产的繁殖技术。为了满足生产需要,以及为了消除由使用实生砧而带来的树木变异,必须设法培养具有自生根系的苗木,用于果园定植。本试验的目的即在于使用化学药剂,诱导沙梨插穗潜在的生根能力,培养自根苗。方法:从7～8年生树上剪取休眠插穗,作前浸泡处理24h,即分别浸入“自来水”、“蒸馏水”和0.01％“硫酸”中。之后,再将以上插穗分别浸泡于吲哚丁酸(IBA)和
Introduction: Pyrus pyrifolia L. is the most successful cultivar in the Himachal Prades hilly region of India with high yield and does not require elaborate management. Generally, people think that it is very difficult for this cultivated species to cut and take root and urgently need to study breeding techniques that can be used in field production. In order to meet production needs and to eliminate tree variations caused by the use of live anvils, it is necessary to try to cultivate seedlings with their own roots for orchard colonization. The purpose of this experiment is to use chemical agents to induce potential rooting capacity of saplings and cultivate self-rooted shoots. Methods: Dormant cuttings were cut from 7 to 8-year-old trees and immersed in tap water, distilled water and 0.01% sulfuric acid for 24 h. After that, the above cuttings were immersed in IBA and IBA respectively
