本试验利用光学显微镜观察了长富—2苹果(Malus pumilla Mill.)试管小植株、移栽于温室和田间的组培苗及一般田间植株四种类型植株叶片的解剖构造,并对各项观测指标进行生物统计。根据对叶片解剖构造观察结果,对造成不同类型植株叶片差异的原因以及试管苗移栽后叶片解剖结构逐渐向田间植株转化等问题进行了讨论。并指出,解剖构造不正常的试管苗移栽后有可能过渡为正常植株,进一步研究缩短过渡期,对提高移栽成活率有重要意义。 In this study, we observed the anatomy of four types of plantlets of Malus pumilla Mill. Plantlets, tissue culture seedlings transplanted in greenhouse and field, and field plants in general. Indicators for biometrics. According to the observation results of the anatomical structure of the leaves, the causes of the differences in the leaves of different types of plants and the transformation of the leaf anatomy of the plantlets after transplanting into the field plants are discussed. And pointed out that the anatomical abnormalities of the tube seedlings after transplanting may transition to normal plants, to further study to shorten the transitional period, to improve the survival rate of transplanting is important.
