| dc.description.abstract | In the present study, the eff ect of the number of harvests on yield and chemical composition of Cichorium spinosum L. plants was examined. Seeds of were sown in seed trays containing peat and young seedlings were transplanted in 2L pots containing peat and perlite (1:1 v/v). Plants were harvested two or three times during the growing period, while control plants (no prior harvests) were also harvested at the same time. Rosette diameter, number of leaves, SPAD index, and fresh and dry weight were recorded at harvest, while chemical composition of leaves was also assessed (fatty-acids, sugars, organic acids, and tocopherols content). Regardless of the number of harvests, total fresh weight and number of leaves were higher comparing to control plants, whereas dry weight and rosette diameter were higher in control plants. SPAD index was mostly aff ected by harvesting time (growth stage) and decreased during the growing season. Signifi cant diff erences were also observed in chemical composition of the aerial parts of plants in relation to the number of harvests, with control treatment for the third cutting having the higher content in sugars, organic acids, saturated and monounsaturated fatty acids, and 1st cutting showed the best results for tocopherols. In conclusion, successive harvests (two or three harvests) increased total yield of C. spinosum plants, comparing to control plants, whereas they had a negative eff ect on sugar, organic and fatty acids content. | pt_PT |
