菠萝品系67-4的叶片组织培养苗和叶片扦插苗,种植在相同的试验条件下,组培苗植株叶片数增长比较快,单株叶片数较多,裔芽、冠芽、吸芽及地下芽数量也较多,但单株叶面积、抽蕾率、平均单果重、小区产量及果实含糖量均比叶插苗低。组培苗未能保持该品系的遗传性,表现了明显的变异。最后,还就影响菠萝组培苗变异的因素及在生产上推广组培苗的问题进行了讨论。 Under the same experimental conditions, the tissue culture seedlings of the pineapple line 67-4 and the cutting seedlings of the leaves were planted under the same test conditions. The number of the leaves of the tissue culture seedling grew more rapidly with more leaves per plant, Bud number is also more, but leaf area per unit, pumping bud rate, the average weight of fruit, cell yield and fruit sugar content than the leaf plug low. Tissue culture seedlings failed to maintain the heredity of the strain, showing obvious variation. Finally, the paper also discussed the factors affecting the variation of pineapple tissue culture seedlings and the promotion of tissue culture seedlings in production.
