The application of S-ABA enantiomer to clusters of poor pigmentation cultivars can improve grape color. The aim of this study was to assess whether S-ABA applied to clusters of the new hybrid ‘BRS Melodia’ seedless grape can improve its color characteristics and to evaluate the consumer acceptance. The following treatments were evaluated: Control; S-ABA at 200 mg·L−1 7 days after veraison (DAV); S-ABA at 400 mg·L−1 7 DAV; S-ABA at 200 mg·L−1 7 DAV + 200 mg·L−1 21 DAV; and S-ABA at 400 mg·L−1 7 DAV + 400 mg·L−1 21 DAV. To apply the treatments, clusters were sprayed using a backpack sprayer until runoff. The exogenous application of S-ABA significantly improves the color of berries of ‘BRS Melodia’ seedless grape, particularly at a concentration of 400 mg·L−1 in two applications, at 7 DAV and 21 DAV, resulting in clusters with greater consumer acceptance through visual-sensory analysis. Regardless of concentration or application timing, there was no change in the physicochemical characteristics of the berries or clusters, nor in the number of shoots per cane or clusters per shoot in the season after its application.

The application of plant growth regulators (PGRs), such as abscisic acid (ABA), putrescine (Put), and 2,4-epibrassinolide (EBR), has been shown to enhance a plant's resistance to various abiotic stresses. However, the protective effects of these PGRs on tomato (Solanum lycopersicum) seedlings under suboptimal temperature stress have not yet been evaluated. We also do not know the most effective method of application of PGRs for various tomato cultivars. We studied the effects of three rates of exogenous ABA, Put, or EBR in limiting damage from suboptimal temperature stress on two tomato cultivars, Zhongshu6 (considered sensitive to suboptimal temperatures) and SANTIAM (considered tolerant to suboptimal temperatures). Results showed that application of these PGRs at appropriate concentrations could effectively reduce the decline in the net photosynthetic rate (Pn) and the chlorophyll (Chl) content in leaves caused by suboptimal temperature stress in both ‘Zhongshu6’ and ‘SANTIAM’ and could promote an increase in organic osmolyte (proline and soluble sugar) contents and root 2,3,5-triphenyltetrazolium chloride (TTC)-reducing activity for ‘Zhongshu6’. However, these effects were inferior on ‘SANTIAM’. For both cultivars, the best treatment concentrations are 1 mm ABA, 0.1 mm Put, or 0.02 μM EBR. Results indicate that in tomato production, exogenous application of ABA, Put, or EBR at appropriate concentrations can effectively limit damage from suboptimal temperature stress.
