摘要
研究了影响大樱桃矮化砧木吉塞拉试管苗移栽于温室和大田成活的因素。认为影响试管苗温室锻炼成活的最重要的因素是镰刀真菌 (Fusariumequiseti)引起的立枯病。使用壮苗在干净的河沙基质上培养 ,发病率低 ,成活率高 ,最高可达 94 %以上。露天炼苗、砂壤土栽植、遮荫网覆盖等措施可提高试管苗在大田的成活率 ,最高可达 95%以上 。
The damping-off disease caused by the fungus Fusarium equiseti was recognized to be the key factor affecting establishment of plantlets in the greenhouse and field after study on factors harmful to transplanting survivor of the sweet cherry dwafted rootstock Gisela (Prunus cerasus × P. canescens).Using high-quality plantlets and fine sand as culture medium improved survivor rate of transplantation up to 94%. A treatment including hardening outdoor,planting on sandy loam and covering with a shading net greatly increased the survivor rate,and ten thousands of plants have been got by this method.
