首次观察了东北山葡萄单性花雌、雄株和两性花类型植株花芽形态分化的各时期,根据分化情况,提出花芽分化的两个关键时期。为制定东北山葡萄合理的高产、稳产栽培管理措施提供了理论依据,并将花芽分化各时期与植株外部形态特征、物候期相结合,可以从植株外形和生育期判断花芽分化进程。
For the first time observed the morphological differentiation of flower buds of hermaphrodite, male and hermaphrodite flowers in northeast mountainous period. According to the differentiation, two key stages of flower bud differentiation were proposed. This study provides a theoretical basis for the rational management of high yielding and steady crop cultivation in northeast mountainous grapes. In addition, the flower bud differentiation process can be judged from the shape and growth stage of the plant by combining the morphological characteristics and phenological stages of the plant during various stages of flower bud differentiation.
