“…This finding is of particular importance for the post-harvest behavior of watermelon fruit, since rind thickness is associated with a better shelf life of fruit and facilitates better transportation of fruit throughout the marketing chain [52]. Similarly to our study, da Luz Neto et al [53] reported that foliar application of Si on mini watermelons resulted in an increase in peel thickness. Based on literature reports, a varied effect of biostimulant application on the crop performance of watermelon was expected, depending on the biostimulant formulation.…”

The aim of the present study was to evaluate the possible effects of two different biostimulant formulations at different application regimes and combined or not with mineral fertilizers (e.g., W1–W8, including the control treatment (no formulations added)) on the yield parameters and fruit quality of watermelon plants. The highest yield was recorded for the W5 treatment due to the formation of more fruit. The highest content of fat, proteins and ash was recorded for treatment W1, whereas carbohydrates were the most abundant in the control treatment, resulting also in the highest energetic value. The main detected sugars in all the tested samples were sucrose and fructose, which were the highest for the W4 and W5 treatments (sucrose) and W4 treatment (fructose). Malic and citric acid were the most abundant compounds, especially in the W4 treatment. In terms of tocopherols, only α-tocopherol was detected, with the highest amounts being recorded for the W4 treatment. Regarding bioactive properties, the lowest IC50 values for OxHLIA were recorded for the W2, W3 and W8 formulations. Moreover, all the extracts exhibited significant anti-inflammatory activity comparable to the positive control, while a variable efficacy of the tested extracts against the studied bacteria and fungi was recorded. In conclusion, our results indicate that simple agronomic practices such as biostimulant application may improve crop performance and improve the proximal composition and the overall quality of watermelon fruit within the context of sustainable crop production.

Salt stress (SS) has emerged as one of the most pressing environmental threats to the production sustainability of oil-seed crops like camelina which necessitates finding out pro-environment and biologically feasible amelioration approaches. A study was performed to investigate the effects of exogenously applied silicon (Si) and selenium (Se) on two camelina varieties (Australian and Canadian) under SS conditions. The trial was comprised of two doses of Si and Se (5 and 10 ppm each) along with two co-application treatments entailing Si (5pp) + Se (5ppm) and Si (10 pp) + Se (10 ppm), whereas control treatments were kept for comparison purpose. The response variables included root-shoot length, fresh and dry weights, as well as leaf photosynthetic pigment content (chlorophyll a, chlorophyll b, total chlorophyll, and carotenoids), leaf gas exchange attributes, biochemical characters (total proline, total soluble sugar, total soluble protein, and total free amino acid) and antioxidant activities (APX, POD, CAT, and SOD). Results showed that SS significantly reduced all growth attributes of camelina, whereas the Australian camelina variety demonstrated greater salinity tolerance in comparison to the Canadian variety. The co-application of Si (10 pp) + Se (10 ppm) outperformed the rest of the treatments by recording the highest leaf chlorophyll a (1.69 mg/g FW), chlorophyll b (1.02 mg/g FW), carotenoids (2.89 mg/g FW), photosynthetic rate (17.02 µmole CO2 m− 2 s− 1), transpiration rate (3.65 µmole CO2 m− 2 s− 1), stomatal conductance (0.38 µmole CO2 m− 2 s− 1), total proline (199.38 µmole/g DW), total soluble sugar (120.95 µmole/g FW), total soluble protein (12.02 mg/g DW) and total free amino acid (37.15 mg/g DW) in Australian camelina as compared to Canadian camelina. The same treatment also remained effective in triggering the activity of APX (3.89 Unit/min/g FW), CAT (165.19 Unit/min/g FW), POD (178.95 Unit/min/g FW), and SOD (237.63 Unit/min/g FW). Thus, the combined exogenous application of Si and Se holds bright perspectives in alleviating the deleterious impact of SS especially for the Australian variety, and could be recommended to camelina growers after thorough field investigations.
