Fruit quality traits of Zizyphus as affected by salinity-induced conditions.
| Traits | Functions | References |
|---|---|---|
| TSS | Decreased nutritional contents, such as TSS, are recorded in fruit trees under saline-induced environments. | [1] |
| AsA | It plays a significant role in reducing the hypoxia-induced oxidative injury in plants. | [47] |
| Phenolic content | Different phenolic compounds are present in fruit trees which mainly protect fruit trees from salinity stress by acting as a glucose-reservoir for osmoregulation and are essential constituents of the antioxidant defense mechanism. | [47] |
| Tocopherols | These have excellent potential to scavenge the excess toxic ROS and lipid radicals in plants. Lipid peroxidation is reduced due to production of tocopherols. These have greater potential to directly repair oxidizing radicals by inhibiting the chain transmission period during lipid auto-oxidation. |
[48] |
| Flavonoids | Lipoxygenase production is restricted by generation of flavonoids; these also contribute well to improving plant defense system salinity stress conditions. | [49] |
| Different sugars | Reducing, non-reducing, and total sugars are drastically reduced due to the excess of salts within fruit tree cells and compartments. | [24] |
| TSP | Its concentration is decreased in leaves of Zizyphus fruit crop due to excessive salt concentrations within the plant cells. | [50] |
TSS = Total soluble solids; AsA = ascorbic acid and TSP = total soluble protein.
