摘要
通过对苹果不同品种花培植株的试管苗及其高接树的染色体数目观察,看到大部分为单倍体,还有其他倍性的植株.幼龄期元帅花培植株的植物学性状与原品种元帅之间有显著差异,表现分枝多、有针刺、叶片小而薄、茸毛少、有缺刻等野生性状.在花培植株之间,也表现有明显的差别.田间高接后,花培植株随树龄增长逐渐向栽培性状转化,元帅花培植株元80—3已开始结果,表现出明显的短枝型特征.
Most of the apple plants derived from anther culture are haploid types and the rest have different ploidy when the chromsome count were made either on the in vitro grown plantlets or the topworked scions. The results of the observation on botanical characters showed that there are significant differences between ather-cultured plants and original 'Delicious' apple plants in the juvenile stage, anther-cultured plants have more branches and thorns lobose, smaller and thinner leaves with less pubescence. There are also significant differences among the anther-derived plants in botanical characters. After topworked in the field, the anther-derived plants gradually change their juvenile characters to the cultivated characters as the tree age increased. A strain of the anther-derived plants from cultivar 'Delicious' began to fruit and showed significant spur-type characteristics. All these indicated that new types of apple can be obtained by anther culture.
