摘要(Abstract)：
通过对薄膜温室2～4年生巨峰、无核白鸡心葡萄整个生育期花芽分化的观察,研究薄膜温室葡萄花芽分化的规律。结果表明,巨峰与无核白鸡心在早期升温条件下,花芽分化比例低,二轴分化程度较浅,不能形成完整的花芽;花芽的形成与树体的营养状况有关。花芽分化开始时磷素水平下降明显,蛋白质含量也有下降,二轴分化期后开始回升,磷素水平也显著提高;更新后花芽的分化与叶龄有关,当叶龄达15d时,开始出现花序原基,叶龄达27d时出现二轴分化期,二轴分化盛期为叶龄46d,花芽分化率平均为91.1%。温室巨峰、无核白鸡心葡萄栽培时,花芽需要靠更新后的新梢形成,因此,加强更新后的新梢管理是达到稳产的关键。
