“…On the whole, the significant antioxidant activities of the ripe fruits in this study may be due to its high contents of antioxidant components including total phenolic, tannins, carotenoids, anthocyanin, vitamin C and vitamin A as showed in Table 1. These results are in accord to earlier studies attributed the antioxidant activity of different plant extracts to their contents of phenolic and flavonoid compounds and others (Mohamed et al., 2016; Ali et al., 2018).…”

This study evaluated nutritional values, bioactive constituents and antioxidant activities of the five wild underutilized fruits in the mountains of southwest Saudi Arabia ( Coccinia grandis (L.) Voigt, Diospyros mespiliformis Hochst. Ex A.Dc., Cissus rotundifolius (L.), Ephedra foeminea Forssk., and Grewia villosa Willd.). The moisture content, crude fibers, total protein, total lipids, total hydrolyzable carbohydrate, total soluble sugars, and total free amino acids were analyzed. The results showed varying amounts among fruits of the five study species. In addition, the mineral composition, amino acid content, phenolic compounds, vitamins, and antioxidant activity were assessed. The highest content of total phenolic and total tannins was measured in D. mespiliformis (20.69 mg/g and 3.84 mg/g) and the lowest in E. foeminea (10.83 mg/g and 1.44 mg/g), respectively. The methanol extract (1 mg/ml) of D. mespiliformis displayed higher percentage of DPPH radical scavenging activity (87.36%). The methanol extract (1 mg/ml) of C. grandis exhibited the highest effect of total antioxidant activity and hydrogen peroxide scavenging activity (71.53%). The sufficient nutritional and antioxidant value of these wild fruits provide healthy food source for the local residents, much the same as many cultivated fruits and vegetables.

“…Likewise, a positive relationship was found between number of clusters per vine, cluster weight and total yield, so increasing number of clusters and cluster weight was parallel with increasing the total yield. Farouk et al, (2014), Mohamed, et al (2014) and Faissal et al (2015).…”

“…The best results were obtained when the vines were fertilized with (50% inorganic N plus 50% compost and algae) which recorded the highest values for TSS (19.67, Farouk et al (2014) and Mohamed, et al (2014). …”

“…Bio fertilizers are the most important for plant production and soil as they play an important role in improving fruit quality and yield grapevines (Akl, et al, 1997). Supplying the vines with N as 25 to 75% inorganic N plus organic manures enriched with algae was preferable in improving quality of the berries in terms of increasing berry weight and dimensions, TSS, Tss/acid ratio and reducing sugars and decreasing total acidity% and both nitrate and nitrite in the juice rather than application of N via inorganic N fertilization alone (Mohamed et al, 2014). Humic acid is the active constituents of organic humus, which can play a very important role in soil conditioning and plant growth and they have different effects on plants (Ferrara and Brunetti, 2010).…”

During 2015 and 2016 seasons, Thompson Seedless grapevines were fertilized with organic fertilizer, compost, humic acid and bio fertilizer (Ascophyliumnodosum) algae. These fertilizers were used as a partial replacement for inorganic N fertilizer improving yield, lowering pollution and enhancing the efficiency of exportation to foreign markets. The obtained results indicated that application of N as 50% inorganic N plus50% organic N and algae 5ml / vine was the best management system for ensuring the best yield, number of clusters /vine and cluster weight, leaf mineral content and improving the chemical characteristics of berries as total soluble solids (TSS), total acidity (TA) and Tss /acid ratio and decreasing nitrate and nitrite content in the berries.
