To elucidate the profiles of plant hormones involved in growth and ripening of grape fruit at various stages, grape bunches of Campbell Early grape bunches (Vitis labrusca ‘Bailey’) which were harvested from 14 to 63 days after full bloom (DAFB) were divided into skin, pulp and seeds. Endogenous plant hormones, which included indole-3-acetic acid (IAA), abscisic acid (ABA), trans-zeatin (Z), isopentenyl adenine (iP), jasmonic acid (JA), methyl jasmonate (MeJA), gibberellin₁ (GA₁), and gibberellin₄ (GA₄), were quantified by liquid chromatography-mass spectrometry (LC-MS). Throughout the sampling period, higher IAA concentrations were maintained in the seeds than those in the skin and pulp. In the seeds, the Z concentration was highest at 14 DAFB and then decreased rapidly. However, in the skin and pulp, the iP concentration increased over the course of sampling. The ABA concentration in the pulp was high around veraison. The JA concentration in the skin reached 4,100 pmol·g⁻¹FW at 27 DAFB. The MeJA concentration in the skin also increased rapidly. These results suggest that increases in iP concentration in the skin and pulp are involved in maturation.

为了阐明在不同阶段葡萄果实生长和成熟所涉及的植物激素的概况，将盛开后14到63天（DAFB）收获的坎贝尔早期葡萄串（Vitis labrusca'Bailey '）葡萄串分为两部分。皮肤，果肉和种子。内源性植物激素，包括吲哚-3-乙酸（IAA），脱落酸（ABA），反玉米素（Z），异戊烯腺嘌呤（iP），茉莉酸（JA），茉莉酸甲酯（MeJA），赤霉素₁（ GA ₁）和赤霉素₄（GA ₄通过液相色谱-质谱（LC-MS）定量。在整个采样期间，种子中的IAA浓度要高于皮肤和果肉中的IAA浓度。在种子中，Z浓度在14 DAFB处最高，然后迅速下降。但是，在皮肤和果肉中，iP浓度在采样过程中增加。纸浆中的ABA浓度在Veraison附近较高。皮肤中的JA浓度在27 DAFB时达到4,100 pmol·g ^-1 FW。皮肤中的MeJA浓度也迅速增加。这些结果表明，皮肤和果肉中iP浓度的增加与成熟有关。
