摘要
以5个优良树莓栽培品种为试验材料,建立了树莓茎尖组织培养体系。结果表明:原初培养采用培养基MS+0.35mg/LBA+0.1mg/L GA1,腋芽萌发率可达85%以上;树莓品种‘早红’和‘美22’增殖培养基采用MS+0.3mg/L GA3+0.1mg/L IAA+0.25mg/L BA+琼脂0.5%,‘澳洲红’采用MS+0.3mg/L GA3+0.3mg/L IAA+0.25mg/L BA+琼脂0.5%,‘黄树莓’采用MS+0.3mg/L GA3+0.3mg/LIAA+0.25mg/LBA+琼脂0.3%,‘黑莓A4-17’采用MS+0.3mg/L GA3+0.3mg/L IAA+0.35mg/L BA+琼脂0.5%,其增殖系数可达5~10;生根培养基采用1/2MS+1.00mg/L IBA,生根率可达70%~90%;移栽适应性培养以河沙作为移栽基质最佳,成活率可达80%以上,但不同品种间有一定差异。
In the present experiment, five raspberry varieties were employed as the experimental materials, the rapid propagation system based on shoot-tip culture had been established. It was found that: the most suitable cultural medium for germination is MS+0.35 mg/L BA+0.1 mg/L GA3 ,germinating rate could reach more than 85 % with the medium. The best media for multiplication are followings: ‘Early-ripening red' raspberry and ‘American No. 22' with MS+0.3 mg/L GA3 +0.1 mg/L IAA+0.25 mg/L BA+agar 0.5%;‘Australia red' raspberry with MS+0. 3 mg/L GA3+0. 3 mg/L IAA+0. 25 mg/L BA+agar 0.5%;'Yellow raspberry' with MS+0. 3 mg/L GA3+0. 3 mg/L IAA+0. 25 mg/L BA+agar 0. 3%; ‘ Blackberry A4-17' with MS+ 0.3 mg/L GA3 + 0. 3 mg/L IAA+ 0.35 mg/L BA+ agar 0.5 %, propagation coefficient could reach 5-10 times. Rooting rate could reach 70%-90% with the medium of 1/2 MS+ 1.00 mg/L IBA. Transplanting surviving rate could reach more than 80% on the river sand.
