Abstract

SummaryDifferent concentrations of aminoethoxyvinylglycine (AVG) and gibberellic acid (GA3) and their combinations, applied at two stages of fruit growth, were evaluated for prolonging the marketing season of `Feicheng' peaches. GA3 applied at the end of pit hardening, or AVG applied two weeks before commercial harvest, inhibited fruit maturation on the tree, delayed harvest and reduced flesh browning after cold storage in a concentration-dependent manner. A synergistic effect was found when both GA3 and AVG were used, with the combination of 100 or 150.mg l±1 GA3, applied at the end of pit hardening, and 100 mg l±1 AVG, applied two weeks before harvest giving the best results. These combinations retarded the change in ground colour, loss of firmness, and reduction in acidity by 2±3 weeks. Since harvest was prolonged by 2±3 weeks, soluble solids content (SSC) in fruit increased compared with the control (harvested earlier). Fruit size was significantly greater on treated trees compared with the controls w...

GA3和AVG组合处理可延缓肥城桃果实成熟，增大果实大小，提高贮藏寿命

摘要研究了不同浓度的氨基乙氧基乙烯基甘氨酸(AVG)和赤霉素酸(GA3)及其组合在两个果实生长阶段对肥城桃果期延长的影响。在果核硬化结束时施用GA3，或在商业收获前两周施用AVG，以浓度依赖的方式抑制树上果实成熟，延迟收获并减少冷藏后的果肉褐变。当GA3和AVG同时使用时，在100或150的组合中发现协同效应。mg l±1 GA3，在坑硬化结束时施用，100 mg l±1 AVG，在收获前两周施用，效果最佳。这些组合延缓了底色的变化、硬度的丧失和酸度的降低2±3周。由于采收时间延长2±3周，果实中可溶性固形物含量(SSC)较对照(采收较早)有所增加。与对照相比，处理树的果实大小显著增大。

期刊介绍： The Journal of Horticultural Science and Biotechnology is an international, peer-reviewed journal, which publishes original research contributions into the production, improvement and utilisation of horticultural crops. It aims to provide scientific knowledge of interest to those engaged in scientific research and the practice of horticulture. The scope of the journal includes studies on fruit and other perennial crops, vegetables and ornamentals grown in temperate or tropical regions and their use in commercial, amenity or urban horticulture. Papers, including reviews, that give new insights into plant and crop growth, yield, quality and response to the environment, are welcome, including those arising from technological innovation and developments in crop genome sequencing and other biotechnological advances.
