Changes in Tomato Fruit Quality and Antioxidant Enzyme Activities under Deficit Irrigation and Fertilizer Application in a Solar Greenhouse in Northwest China
4
TL;DR: In this paper, the quality of fresh fruit and antioxidant enzymes of tomato crops (Lycopersicon esculentum mill) were investigated under different irrigation conditions (low water content [Wl]: 50-~-60% field moisture capacity (FMC); moderate [Wm]: 70-~80% FMC; and high [Wh]: 90 −~-100%FMC) and fertilizer conditions (deficit fertilizer [Fl]: 195 −kg−ha−1 nitrogen (N) + 47 −kg ǫ−1 phosphorus pentoxide (P2O

Abstract: The interaction between water availability in the soil and fertilizer application rates often strongly affects crop growth. In the current study, the quality of fresh fruit and antioxidant enzymes of tomato crops (Lycopersicon esculentum Mill) were investigated under different irrigation (low water content [Wl]: 50 ~ 60% field moisture capacity (FMC); moderate [Wm]: 70 ~ 80% FMC; and high [Wh]: 90 ~ 100% FMC) and fertilizer conditions (deficit fertilizer [Fl]: 195 kg ha−1 nitrogen (N) + 47 kg ha−1 phosphorus pentoxide (P2O5) and moderate [Fm]: 278 kg ha−1 N + 67 kg ha−1 P2O5) in a solar greenhouse. The results showed that the quality of fresh fruits and the antioxidant enzyme activities in the leaves and fruits were related to the water content in the soil. Deficit irrigation improved the fruit quality and 50 ~ 60% FMC combined with fertilizer application rates of 195 kg ha−1 N + 47 kg ha−1 P2O5 is recommended for tomato crop cultivation under greenhouse conditions.

Exogenous Melatonin Improves Fruit Quality Features, Health Promoting Antioxidant Compounds and Yield Traits in Tomato Fruits under Acid Rain Stress
TL;DR: The study results showed that the fruits of SAR-stressed plants had higher quality traits and antioxidant bioactive compounds by increasing antioxidant activities against SAR-induced oxidative stress compared with fruits of control plants, and these improvements to antioxidant activities in fruits under SAR-condition remained unable to prevent the reduction of the yield.

Vasiliki Liava,Christina Chaski,Mikel Añibarro-Ortega,Alexis Pereira,José Pinela,Lillian Barros,Spyridon Alexandros Petropoulos +6 more
TL;DR: This study investigates the effect of biostimulants and deficit irrigation on processing tomato quality, revealing that regulated deficit irrigation and biostimulant application can increase energetic value, carbohydrates, and free sugars content, while also affecting tocopherols, carotenoids, and antioxidant activity.

Biomass, fruit yield, water productivity and quality response of processing tomato to plant density and deficit irrigation under a semi-arid Mediterranean climate
Cristina Patanè,Alessandro Saita +1 more
TL;DR: The yield response factor, Ky, which correlates relative fruit yield losses to relative ETc reduction, was higher than Kss, revealing a greater crop sensitivity to soil-water deficit in terms of fruit yield than dry biomass, which may be of use in identifying the plant density at which water productivity is maximised or yield losses are minimised.
Effects of water stress on the organic Acid and carbohydrate compositions of cotton plants.
TL;DR: Under stress, sucrose accumulation was observed in wilting strains (poor performers) and the most dramatic response to water stress was the accumulation of citric acid in strains T25 and T256 as compared to T185 and T466.
Oxidative damage and defense mechanisms in primary leaves of Phaseolus vulgaris as a result of root assimilation of toxic amounts of copper
Jolanda Weckx,Herman Clijsters +1 more
TL;DR: A transient increase of products of membrane peroxidation was observed in the primary leaves of Phaseolus vulgaris during the period of Cu uptake, mainly due to the oxidizing properties of copper itself and not to a stimulation of the lipoxygenase activity.
The Effects of Water Stress on the Growth, Sugar and Nitrogen Content of Cherry Tomato Fruit
TL;DR: The optimum pF value ranges between pF 2.5 and 2.9, within which is optimum tomato fruit quality without any reduction in yield, which suggests that the low nitrogen content may account for the high sugar content.
Water tension thresholds for processing tomatoes under drip irrigation in Central Brazil
TL;DR: Total soluble solids content was not affected by irrigation treatments during vegetative and fruit development stages, but increased as SWT increased during fruit maturation growth stage, and maximum fruit yield was reached when irrigations were performed at SWT thresholds of 35, 12, and 15 kPa.
