荷包花离体繁殖研究初报

Reports of The Dicentra Pusilla Exsomatize Reproduction

植物激素的种类和不同的组合配比对荷包花的离体繁殖有很大影响。结果表明:诱导芽阶段以MS+BA 2 mg/L+IBA 0.2 mg/L效果较好;丛生芽增殖阶段以MS+BA 2 mg/L+NAA 0.1 mg/L较好;而培养基中低浓度的无机盐有利于生根,故1/2MS+IBA 1 mg/L有较好的生根效果。试管苗移栽以腐殖土∶蛭石=2∶1的栽培基质效果较好。

The plant hormone type and the different combination allocated proportion have the very tremendous influence to Dicentra pusilla＇s exsomatize reproduction. The test result indicated that, the induction bud stage induced by the MS＋BA 2 mg/L＋IBA 0. 2 mg/L was the best; the bud multiplication stage induced by MS＋BA 2 mg/L＋NAA 0. 1 mg/L grows thickly; But in the culture medium the low concentration inorganic salt was advantageous in taking root, therefore 1/2MS＋IBA 1 mg/L had the best effect for taking roots. The test tube seedling transplants by the humus soil ： Vermiculite =2 ： 1 cultivation matrix effect was good.
