在固体组织培养研究的基础上，试用浅层液体静置培养技术，进行橡皮树茎尖组织培养快速繁殖效果良好。此法同时省去琼脂，简化培养基，用砂糖代替蔗糖，用自来水代替蒸馏水，省去肌醇，使培养基成本降低了９５．８９％。试管苗管外扦插生根率达９４．３％，降低成本９５．７％。两项技术措施使组培苗成本降低３５．６％。 On the basis of solid tissue culture research, the shallow liquid static culture technique was used to test the rapid propagation of stem tips in tissue culture. This method also eliminates the need for agar, simplifies the medium, sugar instead of sucrose, tap water instead of distilled water, eliminating inositol, the media costs reduced by 95.89%. Test-tube seedlings cuttings rooting rate of 94.3%, reducing the cost of 95.7%. Two technical measures to reduce the cost of tissue culture seedlings 35.6%.
