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 ,几万株试管苗已成功地移栽于大田
The factors that affect the transplanting of Gigantra testis seedlings in dwarfing cherry stock in greenhouse and field were studied. It is considered that the most important factor that affects the survival of in vitro greenhouse plantlets is the blight caused by Fusariumequiseti. The use of strong seedlings in a clean river sand substrate culture, the incidence is low, high survival rate, up to 94% or more. Cultivation of alfalfa, cultivation of sandy loam soil, coverage of shady nets and other measures can increase the survival rate of test tube seedlings in the field, up to 95% or more. Tens of thousands of test tube seedlings have been successfully transplanted in the field
