As plant growth regulators, gibberellic acid (GA₃) and CPPU [forchlorfenuron, N-(2-chloro-4-pyridinyl)-N-phenylurea] are widely used in the production of table grapes. However, how these compounds regulate the aroma quality remains unclear. By measuring free and bound aroma compounds in Shine Muscat grapes from eight groups during whole growth period, GA₃ and CPPU were both found to significantly promote the synthesis of acyclic monoterpenes and (E)-2-hexenal, and double applications were found to further increase the aroma compound contents. On the other hand, GA₃ and CPPU obviously promoted the expansion of berries, and the effect of promoting the synthesis of aroma compounds was largely diminished. In conclusion, free compound concentrations in berry were almost unaffected by GA₃ and CPPU. From the perspective of aroma compounds, a highly concerted interplay was observed for terpenes, and bound compounds exhibited higher correlations than those of free compounds. In addition, 17 compounds could be used as markers that indicated the developmental timing of berries.

作为植物生长调节剂，赤霉酸（GA ₃）和CPPU [for chlorfenuron, N-(2-chloro-4-pyridinyl)-N-phenylurea]广泛用于鲜食葡萄的生产。然而，这些化合物如何调节香气质量仍不清楚。通过对8组Shine Muscat葡萄全生育期游离和结合香气物质的测定，发现GA ₃和CPPU均能显着促进无环单萜和( E )-2-己烯醛的合成，并发现双重施用进一步增加香气化合物含量。另一方面，GA ₃而CPPU明显促进浆果膨大，促进香气物质合成的作用大大减弱。总之，浆果中的游离化合物浓度几乎不受 GA ₃和 CPPU 的影响。从芳香化合物的角度来看，萜烯之间存在高度协调的相互作用，结合化合物比游离化合物表现出更高的相关性。此外，有 17 种化合物可用作指示浆果发育时间的标记。
