摘要
[目的]探究延后栽培中控温方式对果树开花坐果的影响。[方法]以冷藏盆栽桃为试材,研究不同出库时期对冷藏盆栽桃开花坐果的影响。[结果]结果表明:随着出库时期延后,冷藏盆栽桃开花物候期加快,花期缩短,花朵直径、花柱长度变短小,僵芽率上升,花粉量、花粉生活力、坐果率下降。花芽萌动至花期的持续高温是造成坐果率下降的主要原因。[结论]该研究为丰富果树休眠理论及盆栽果树、设施果树的延后生产提供了理论依据。
[Objective] The objective of the research was to investigate the effects of controlling temperature pattern on flowing and fruit-setting of fruit tree in delayed cultivation.[Method] Taking refrigerated pot peach as tested materials,the effects of different periods of stopping cold storage on flowering and fruit-setting of potted peach were studied.[Result] With the delay of periods of stopping cold storage,flowering phenophase in potted peach was quicken,florescence was shorten,bloom diameter and polar length were shorten,freezing bud rate was raised , and pollen amount, pollen viability and fruit-setting rate were decreased. Continuous high temperatttre from flower bud germination to florescence wasa major reason that caused the decrease of fruit-setting. [Conclusion] The research provided theoretical basis for enriching dormancy theory of fruit tree and delaying production of potted and facilities fruit tree.
