Non-climacteric blueberry (Vaccinium spp.) fruits accumulate high levels of anthocyanins during ripening, which are a good source of dietary antioxidants. This study examined the effects of exogenous abscisic acid (ABA) application on fruit characteristics and anthocyanin accumulation in a northern highbush blueberry (V. corymbosum 'Jersey') during development. Fruits on shrubs were treated with 1gL ABA before the initiation of fruit colouration. Application of ABA temporarily increased the level of ABA in the fruits during development. Exogenous ABA had no obvious effect on fruit growth, but stimulated fruit colouration by accelerating the accumulation of individual anthocyanins, mainly malvidin, delphinidin and petunidin glycosides. This is the first report to show that ABA promotes the accumulation of anthocyanins in blueberry fruits. However, exogenous ABA also promoted fruit softening, which is undesirable during harvest and shelf life.
非跃变型蓝莓（Vaccinium spp.）果实成熟过程中积累高水平的花色苷，花色苷是膳食抗氧化剂的良好来源。本研究探讨了外源脱落酸（ABA）处理对北方高丛蓝莓（V. corymbosum 'Jersey'）果实发育过程中果实特征和花色苷积累的影响。在果实开始着色前，用 1gL ABA 处理植株上的果实。ABA 的施加在果实发育过程中暂时增加了 ABA 的水平。外源 ABA 对果实生长没有明显影响，但通过加速单个花色苷（主要是矢车菊素、飞燕草素和锦葵素糖苷）的积累来刺激果实着色。这是首次报道 ABA 促进蓝莓果实中花色苷的积累。然而，外源 ABA 也促进了果实软化，这在收获和货架期是不理想的。
