Abstract

Suitable postharvest treatment methods were investigated to improve the color of grape berries. Culture solutions containing jasmonic acid (JA), methyl jasmonate (MeJA), and prohydrojasmon (PDJ) enhanced the skin coloration of grape berries ('Pione') harvested at the initial stage of coloration. MeJA vapor treatment under sealed conditions increased anthocyanin accumulation in grape berries ('AkiQueen' and 'Pione') harvested at the early stage of skin coloration. Furthermore, promoting skin coloration by MeJA vapor treatment was as effective in mature clusters as it was in detached berries. These effects were confirmed in light conditions but not in constant darkness. Our results showed that postharvest MeJA vapor treatment improved skin coloration in grapes. In addition, postharvest treatment with MeJA was found to have no effect on the endogenous abscisic acid content of grape berry skins. Therefore, we suggest that MeJA vapor treatment can be a useful and labor-saving method for the horticultural industry.

外源茉莉酸甲酯和光照条件对葡萄果实色泽及内源脱落酸含量的影响。
研究了适宜的采后处理方法,以改善葡萄果实的色泽。含有茉莉酸(JA),茉莉酸甲酯(MeJA)和原氢茉莉(PDJ)的培养溶液增强了在着色初期收获的葡萄浆果(“Pione”)的皮肤颜色。密封条件下的MeJA蒸汽处理增加了在皮肤着色早期收获的葡萄浆果(“AkiQueen”和“Pione”)的花青素积累。此外,通过MeJA蒸汽处理促进皮肤颜色在成熟的簇中与在分离的浆果中一样有效。这些效应在光照条件下得到证实,但在持续的黑暗条件下则不然。我们的研究结果表明,采后MeJA蒸汽处理改善了葡萄的果皮颜色。此外,采后MeJA处理对葡萄果皮内源脱落酸含量没有影响。因此,我们认为MeJA蒸汽处理对园艺工业来说是一种有用且节省劳动力的方法。
