“…These variations can be attributed to the different farming system cover types, which resulted in different radiation intensities during the cultivations. A correlation between the pigment synthesis of red and green lettuces and different light intensities during cultivation was also confirmed by other authors . Evaluating the green cultivars, the average spectra of Crystal and Regina overlapped in the visible region for the hydroponic system, and an overlapping was also verified in the NIR range for the organic system.…”

The proposed models were adequate for estimating lettuce pigments in a quick and non-destructive way, representing an alternative to conventional measurement methods. Prediction accuracies were improved by using the detrending, smoothing and first derivative pretreatments to the original spectral signatures prior to estimating lettuce chlorophyll, carotenoid and anthocyanin content, respectively. © 2016 Society of Chemical Industry.

“…The higher total phenolics in lettuce was also noted by Perez-Lopez et al [35] in two lettuce cultivars along with total glutathione and carotenoids content at elevated CO2 level. Similarly, Zhang et al [23] showed that elevated [CO 2 ] could improve health-promoting and sensory qualities of tomato fruits grown in greenhouse.…”

“…At elevated [CO 2 ], there was significant increase in the dry biomass accumulation in lettuce, more than 18% over the ambient CO 2 level (Figure 6). Similar results have been observed in lettuce especially with shoot biomass [36] but the results are variable depending on the cultivar [35]. Although lettuce plants grown at elevated [CO 2 ] increased their biomass, their overall leaf area decreased with much greener and thicker leaves compared to their counterparts grown at ambient [CO 2 ].…”

Rising global CO 2 levels are a major factor that impacts not only the environment but also many plant functions including growth, productivity and nutritional quality. The study examined the impact of elevated [CO 2 ] on nutritional quality and growth characteristics of lettuce (Lactuca sativa) and spinach (Spinacia oleracea). Elevated [CO 2 ] decreased the concentration of many important nutrients including nitrogen (protein), potassium and phosphorus in the edible parts of both lettuce and spinach. The nitrogen concentration in lettuce shoots was reduced by more than 30% at elevated [CO 2 ] compared to the plants grown at ambient level of CO 2 . Similarly the concentration of a number of micronutrients including sulfur, zinc, copper and magnesium, was depressed in lettuce shoots. Although the total phenolic content and antioxidant capacity were higher in lettuce at elevated CO 2 , they were not affected in spinach. The photosynthetic activity was variable among the plant species while there was no increase in the carbon accumulation in these plants at elevated [CO 2 ]. However, there was significant reduction in the leaf stomatal conductance in both lettuce and spinach in response to higher [CO 2 ], which is likely affect both water loss from the leaves and their photosynthetic activity. The results indicate a broad adverse impact of rising [CO 2 ] on the nutritional quality of commonly consumed leafy vegetables namely, lettuce and spinach.

“…Similarly, Becker et al (2014Becker et al ( , 2013 reported that the effect of radiation intensity on phenolic compounds composition of lettuce plants is compound dependent and apart from environmental factors, plant ontogeny is also important. In another study, Pérez-López et al (2015) also observed that lettuce plants treated with high light intensities contained higher concentrations of carotenoids, glutathione, total phenols and anthocyanins, which was also the case in our study regarding total phenolic compounds content.…”

A B S T R A C TNitrogen fertilizer form may affect quality and yield of leafy vegetables. In the present study, the effect of ammonium nitrogen rates on yield and chemical composition of Cichorium spinosum L. was examined. Five fertilizer treatments with different amounts of ammonium nitrogen (F1: 14%, F2: 24%, F3: 34%, F4: 43% and F5: 53% NH 4 -0N of total N) were applied. Fertilizer treatments had a significant effect on both plant fresh weight and chemical composition, depending on growing period and harvest stage. For both harvests of the 1st growing period, yield was higher in treatments F4 (43% NH 4 -N) and F5 (53% NH 4 -N), whereas in the 2nd growing period yield was higher for treatments F1, F2 and F3. Moreover, the highest content of total phenolics were recorded in the 2nd growing period. Antioxidant properties were also affected by fertilization treatments and growing periods, with antioxidant potency being higher in the 2nd growing period and for treatments F1 and F2. According to the results of the present study, nitrogen fertilizer form should be considered together with growing period and harvest stage as a useful means towards increasing the quality of the final product without compromising total yield.
