AB  - In the present study, three red-colored (Dark Opal, Basilico Rosso, and Red Basil) and one green-colored landrace (Mitikas) of basil (Ocimum basilicum L.) were grown under four nitrogen regimes, namely Control (no fertilizer added), 200 ppm, 400 ppm, and 600 ppm of nitrogen (N). Fresh yield varied depending on N input following a quadratic function in all four genotypes, and green basil performed better compared to the red cultivars. A significant interaction of genotype × N input was recorded for most of the chemical parameters measured. Tocopherols contents of leaves were consistently higher in plants that received 200 ppm of N and lower in those receiving 600 ppm of N, especially in Dark Opal and Red Basil cultivars. Polyunsaturated fatty acids (PUFA) were the major category of fatty acids and Red Basil had the lowest ratio of omega-6/omega 3 (0.29) and thus the best fatty acid profile. Polyphenols content was the highest in Red Basil and Dark Opal (25 mg/g of extract on average) and the lowest in Mitikas and decreased with increasing N input. Similarly, antioxidant activity was the highest in Dark Opal and Red Basil fertigated with 200 ppm of N, whereas all the leaf extracts tested had good antibacterial and antifungal activity. In conclusion, basil chemical and bioactive profile was significantly influenced by both genotype and N input. Red-colored basil, although less productive, had the best chemical profile, and moderate levels of N input may provide the best compromise between yield, nutritional value, and bioactivity for the species.

AB  - Centaurea raphanina subsp. mixta (DC.) Runemark is a wild edible species endemic to Greece. This study evaluated the chemical composition and bioactive properties of wild and cultivated C. raphanina subsp. mixta plants. Wild plants had higher nutritional value than cultivated ones, whereas cultivated plants contained more tocopherols. Glucose and sucrose were higher in cultivated plants and trehalose in wild ones. Oxalic and total organic acids were detected in higher amounts in cultivated samples. The main fatty acids were α-linolenic, linoleic and palmitic acid, while wild plants were richer in polyunsaturated fatty acids. Two pinocembrin derivatives were the main phenolic compounds being detected in higher amounts in wild plants. Regarding the antioxidant activity, wild and cultivated plants were more effective in the oxidative haemolysis (OxHLIA) and thiobarbituric acid reactive substances (TBARS) assays, respectively. Moreover, both extracts showed moderate cytotoxicity in non-tumor cell lines (PLP2), while cultivated plants were more effective against cervical carcinoma (HeLa), breast carcinoma (MCF-7) and non-small lung cancer (NCI-H460) cell lines. Finally, wild plants showed higher antimicrobial activity than cultivated plants against specific pathogens. In conclusion, the cultivation of C. raphanina subsp. mixta showed promising results in terms of tocopherols content and antiproliferative effects, however further research is needed to decrease oxalic acid content.

AB  - The intensification of horticultural crops cultivation makes urgent the seeking for alternative growth substrates that could substitute non-renewable and/or synthetic growing media, such as peat and rock wool. The aim of the present study was to evaluate the potential use of byproducts from two industrial crops commonly cultivated in the Mediterranean basin, namely cardoon and cotton, as growth substrates for Cichorium spinosum, while zeolite addition was also tested as a soil amendment. A pot experiment was carried for two consecutive growing periods and plant growth was evaluated for six growing media compositions, while plant extracts were also evaluated in terms of their phenolic compounds profile, antioxidant and antimicrobial activities. The results of this study showed that cotton byproducts and zeolite may partially substitute peat in growth substrate of C. spinosum and high yields comparable to peat may be achieved. Phenolic compounds content and antioxidant activity of leaves' extracts was higher for plants grown in soil which showed severe stress symptoms comparing to the other tested substrate blends. Antimicrobial activity was also affected by growth substrate composition, only in the case of antibacterial properties of leaves' extracts, whereas none of the extracts presented significant antifungal activities. In conclusion, the use of cotton ginning byproducts and zeolite in growth substrate blends may partially substitute conventional substrates as peat in horticultural crops production, resulting in reduction of production cost and lessening of bulky byproducts’ management and related environmental burden without compromising yield.
