Study of effect of ABA treatment on the quality of ‘Zitian seedless’
Journal Title: Journal of Henan Agricultural University - Year 2023, Vol 57, Issue 5
Abstract
[Objective] To explore the regulation role of exogenous treatment of abscisic acid (ABA) on grape quality. [Method] ‘Zitian seedless’ grape was used as tested materials and treated with 300 mg·L-1 ABA at the beginning of the véraison. Single berry weight, diameter of longitudinal and transverse, berry firmness in berries, total soluble solid, titratable acid, and anthocyanin content and chlorophyll content in pericarp were measured, ABA content in berries was determined by HPLC-ESI-MS/MS. The expression pattern of anthocyanin biosynthesis pathway genes, chlorophyll degradation pathway genes and ABA biosynthesis pathway genes were detect by real-time PCR. [Result] Exogenous application of ABA could significantly increase single berry weight, diameter of longitudinal and transverse, total soluble solid, ABA content in berries, and anthocyanin content in berry skin, decrease the titratable acid, firmness of berries and chlorophyll content in pericarp, and result in variation of the related genes expression of anthocyanin biosynthesis pathway, chlorophyll degradation pathway and ABA biosynthesis pathway. [Conclusion] During the growth and development of grape fruits, ABA in the transition could promote fruit growth, coloring and softening, accelerate the accumulation of anthocyanin and chlorophyll degradation in the grape skin, and thus promote fruit ripening and improve the quality of grape fruit.
