“…Similarly, in this study, the highest tomato phenolic acid content among the five treatments was chlorogenic acid. Most phenolic acid components were improved to some extent in the water-deficit treatment, which is consistent with our findings [ 45 ]. Remarkably, the content of various phenolic acids in the T2 treatment was significantly higher than that in the CK (protocatechuic acid, chlorogenic acid, gallic acid, gentisic acid, benzoic acid, and cinnamic acid).…”

“…Applying a moderate water deficit in the middle and late stages of fruit development optimizes fruit quality with small yield losses [ 51 , 52 ]. Water deficit increased soluble-sugar accumulation and decreased organic-acid content in both grape [ 28 , 45 ] and tomato crops [ 52 ]. However, Terry et al [ 53 ] found that the water deficit increased sugar contents but did not affect acid content in strawberries, which is consistent with our results.…”

Tomatoes have high nutritional value and abundant bioactive compounds. Moderate water deficit irrigation alters metabolic levels of fruits, improving composition and quality. We investigated the effects of water deficit (T1, T2, T3, and T4) treatments and adequate irrigation (CK) on tomato polyphenol composition, antioxidant capacity, and nutritional quality. Compared with CK, the total flavonoid content increased by 33.66% and 44.73% in T1 and T2, and total phenols increased by 57.64%, 72.22%, and 55.78% in T1, T2, and T3, respectively. The T2 treatment significantly enhanced antioxidant’ capacities (ABTS, HSRA, FRAP, and DPPH). There were multiple groups of significant or extremely significant positive correlations between polyphenol components and antioxidant activity. For polyphenols and antioxidant capacity, the classification models divided the treatments: CK and T4 and T1–T3. The contents of soluble solids, soluble protein, vitamin C, and soluble sugar of the treatment groups were higher than those of CK. The soluble sugar positively correlated with sugar–acid ratios. In the PCA-based model, T3 in the first quadrant indicated the best treatment in terms of nutritional quality. Overall, comprehensive rankings using principal component analysis (PCA) revealed T2 > T1 > T3 > T4 > CK. Therefore, the T2 treatment is a suitable for improving quality and antioxidant capacity. This study provides novel insights into improving water-use efficiency and quality in the context of water scarcity worldwide.

“…In contrast to the CK, the root restriction with three indicators (flavonoid, betaine, and ascorbic acid) showed significant growth trends, especially betaine, which twofold (Table 2) in our study. Moreover, root-restriction regulation could significantly increase soil organic matter and organic carbon content, and this change was beneficial in improving the fruit quality of wolfberry (Figure 4), which was similar to results found by other researchers [24]. The reason may be the slow release of nutrients in the process of organic fertilizer decay, which can synchronize with the physiological needs of wolfberry, improve the fertilizer utilization efficiency, increase the mineralization process of organic nutrients, improve the soil nutrient pool source, and increase the content of total and available nutrients in soil [25,26].…”

The root restriction of protected cultivation has been widely used to increase productivity and sustainability in modern agriculture. However, there have been few studies of wolfberry (Lycium barbarum) root restriction, and it is cultivated mostly by clean tillage. In this study, we measured the growth of Lycium barbarum and the composition and diversity of the bacterial community and soil properties of L. barbarum under different cultivation methods with root restriction. The results showed that the X60 root-restriction treatment significantly increased the canopy size (east–west), leaf length, leaf width, the number and length of new branches, and the concentrations of chlorophyll and K in L. barbarum. The concentrations of N, P, and K in the root-restriction groups were all higher than those in CK. However, the ratio of N:P was greatest in the CK plants and least in X80, indicating that X80 had a relatively weak effect on the balance of N:P. In addition, root restriction improved fruit quality by increasing soil organic matter and organic carbon and also improved fertilization efficiency to promote plant growth. Moreover, high-throughput sequencing showed that the abundance of soil bacteria under root-restriction cultivation was significantly higher than that in CK. Furthermore, the total abundance of the top 10 bacterial genera was greatest in the X60 treatment. Redundancy analysis showed that total N, total P, total K, and total organic matter were the major soil factors that affected the bacterial community. A comprehensive comparison showed that root-restriction cultivation improved the growth of L. barbarum but reduced the abundance and diversity of the soil bacteria. The X60 treatment yielded the best results on plant growth. Our findings provide an empirical reference for root-restriction cultivation of L. barbarum of an appropriate width.

“…A grape’s taste and quality are closely related to the basic physical-chemical composition and to the secondary metabolites produced (phenolic compounds (PC), and volatiles) [ 9 ]. It is known that the maturation of a grape and consequently its phenolic composition are influenced by several biotic and abiotic factors, such as by the variety or cultivar, edaphoclimatic conditions of growth and the vegetative and reproductive development of the grapevine [ 6 , 10 ], through different viticultural practices such as the use of different rootstocks [ 11 , 12 ], the irrigation of vineyards [ 6 ] and the use of plant hormones or growth regulators [ 13 , 14 ].…”

The BRS Carmem grape was developed as an alternative for processing juices and wines. This study aimed to determine the phenolic compounds (PC) in the edible parts of this grape from two harvests—one harvested at ideal maturation time and another when the grapes were still immature—using HPLC-DAD-ESI-MS/MS. Student’s t-test was used (α = 0.05) to evaluate differences in the PC content between the edible parts and between the harvests. Both skins showed a predominance of flavonols, anthocyanins, hydroxycinnamic acids derivatives (HCAD) and stilbenes, with higher concentrations for harvest 1 than harvest 2. For both harvests (harvest 1 and harvest 2), the HCAD (mg of caftaric acid•kg fruit−1) was higher in whole grapes (383.98 and 67.09) than in their skins (173.95 and 21.74), with a predominance of trans-caffeic acid for all samples; the flavan-3-ols and proanthocyanidins (mg of (+)-catechin•kg fruit−1) presented higher concentrations in the seeds (flavan-3-ols: 203.20 and 182.71, proanthocyanidins: 453.57 and 299.86) than in the skins (flavan-3-ols: 1.90 and 4.56, proanthocyanidins: 37.58 and 98.92); the stilbenes concentration (µg 3-glc-resveratrol•kg fruit−1) was higher for the seeds from harvest 2 (896.25) than those from harvest 1 (48.67). BRS Carmem grapes contain a phenolic composition complex, and still have a relevant concentration of flavonols, anthocyanins and stilbenes, even when immature.
