The Cultivation and Vitro Rapid Propagation of the Test Tube Seedlings of Musa AAA Red Green

红皮香蕉 (MusaAAARedgreen)离体培养快速繁殖结果表明 ,用MS培养基 ,附加BA3～ 5mg/L(单位下同 )、NAA0 .2、3.0 %蔗糖 ,培养室温度保持在 2 5～2 8℃ ,丛生芽分切转入诱根培养基 ,即MS +NAA0 .5 +IBA0 .5、添加 0 .3% (w/v)活性炭 ,就可形成完整的试管苗植株 .移入薄膜大棚内栽培 ,栽培基质采用塘泥∶河沙为 1∶1 ,成活率高达 95 %以上 ,可商品化生产 .

The vitro rapid propagation of Musa AAA Red green indicates that, with medium MS, BA3～5, NAA0.2, 3.0%sugar and the temperature of 25～28 ℃ in the culture room, buds crowds can be cut and planted in rootage medium[MS+NAA0.5+IBA0.5+0.3%(w/v)active carbon], thus, the complete planting of the buds can be done. Once cultivated in big shed covered with plastic film, in the culture ground of pond silt and sand at the proportion of 1:1, the survival rate of the test tube seedlings can be above 95% and it′s time for a large scale production. Attention should be focused on the culture management of the seedlings in the process of field culture.
