【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。更多还原

【Abstract】 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%.更多还原
