摘要
将改良培养技术应用于银中杨组培快繁育苗,结果表明:以芽作为繁殖材料进行继代扩繁时,采用改良培养技术较常规培养技术可降低生产成本50%左右;苗茎增粗11.2%,单株鲜重增加48%,生根苗的移栽成活率可达到97.8%,而常规培养技术的移栽成活率只有81.3%,提高了16.5个百分点,效果显著。
Improved techniques is used in tissue culture of Populus alba × berolinensis, and the results showed that when reproductive materials of the bud were propagated , the production costs was reduced of 50% than conventional techniques; This technique also increased stem tickening of 11.2%, individual fresh weight of 48% ;The survival rate of transplanted seedings of 97,8% is higher than the conventional seeding of 81.3%, it is very effective.
