摘要
本试验从前移栽期(生根培养阶段)、移栽期,选择了影响甘蔗组培苗假植成活率的几个关键困素,如 NAA、多效唑、苗床成份等进行试验研究。试验结果表明:1.基本培养基加 NAA 4-5 mg/L、多效唑2-3mg/L时,可获得根壮、苗绿的组培苗,其假植成活率可达80％以上;2、苗床成份为上层砂+底层泥土的一级苗更适合于甘蔗组培苗的生长,假植成活率可达 75％以上。
This experiment studies on the factors affecting transplanting survival rate of sugarcane regenerated plantlets in primary nursery, such as the concentration of NAA and PPP3 in the pre-transplanting stage, and 自动 the components of planting plot in the transplanting stage. The result show that: (a) basic medium supplemented with NAA 4-5 mg/L and PPP3 2-3 mg/L is very effective for well rooting and even growing of sugarcane regenerated plantlets and the transplanting survival rate reaches more than 80%; (b) the rooted sugarcane regenerated plantlets grows well in the planting plot with components of upper layer-sand and lower layer soil, and it's transplanting survival rate reaches more than 75%.
