优质脱毒枣苗工厂化育苗技术研究

应用生物技术从优质枣苗的脱除菌原体（ＭＬＯ）到启动组培技术、增殖培养技术、生根培养技术，组培苗无土栽培和温室营养钵栽培及室外炼苗大田绿叶移栽技术进行了系统试验。完成了脱毒枣苗工厂化育苗开发研究。结果生根率达到９４％。大田绿叶移栽成活率达到９８％，枣苗当年生长高度达到４０－８０ｃｍ，第二年生长高度可达到１１５－１８０ｃｍ，该项技术对于长期以来红枣生产中的遇到的繁殖慢、品质差、枣疯病日趋严重三大难题提

A Study on the Industrial Breeding Technology of High quality Virus free Date Seedlings

The present study applied biotechnology on the industrial breeding of virus free date on a small scale .The study completed systematic researches from the removal of MLO to tissue culture initiation,proliferative culture,root inducing culture,the soil less cultivation of tissue cultured seedling,greenhouse pot cultivation;field acclimatiation and transplanting technology of greenleaf plants to fields.The rooting rate was 94%.The survival rate of transplanting was 98%.The high quality date seedling could develop to 40-80 cm high in one year,and the next year it could reach 115-118 cm high.This technology provided effective ways for solving the three baffling problems,i,e,slow propagation,lower quality and serious virus diseases found in the jujube production.
