Yield, quality and drought sensitivity of tomato to water deficit during different growth stages

Abstract: In areas where the supply of water for irrigation is limited, tomato production is often subject to drought stress. In order to investigate the drought sensitivity of tomato (Lycopersicon esculentum Mill.) yield and quality during different growth stages, field and pot experiments were conducted in a high tunnel in southern China during the 2013 and 2016 growing seasons. The experiments consisted of four treatments. Crops were drip-irrigated to 100 % of field capacity at all growth stages divided into treatmen… Show more

“…In our work, water use efficiency ranged from 1.8 to 37.8 kg/m 3 (average: 13.7 kg/m 3 ), values that fall in the range of values reported in the literature (e.g., 35-50 [65,66], 9-16 [67], 13-33 [68], or 25-50 kg/m 3 [12]). These results show that farmers can improve the WUE of long shelf life tomato cropping systems.…”

“…Low-input management practices maximize WUE, and significant progress towards optimal yield/WUE relationships can be achieved by breeding genotypes adapted to these environments. In these farming systems, various authors have shown that controlled water deficit strategies can substantially improve WUE in exchange for a slight decrease yield, which is however accompanied by an increase in fruit quality parameters [65,[69][70][71]. On the other hand, under "conventional" commercial conditions, it is crucial to adjust irrigation and fertilization doses to the requirements of the crop to attain good WUE.…”

“…In addition, Microporous membrane irrigation was beneficial to the accumulation of N, P and K in tomato plants in this research. Previous studies have found that the accumulation of nutrient elements in plants was often positively correlated with the growth of plants (Cui et al, 2020;Jiang et al, 2019). This indicated that the treatment of microporous membrane irrigation could improve the soil moisture content, increase the nutrient absorption of tomato plants and then promote the growth of tomato.…”

“…Close positive relationships between the leaf transpiration and stomatal conductance measured at early flowering vs. the number of flowers produced indicated how the plant water status at flowering greatly affected its reproductive behavior (the higher the leaf transpiration and stomatal conductance, the greater the number of flowers produced). Indeed, flowering has been reported as the most sensitive stage of tomatoes to water stress [25,26]. Torrecillas et al [27] noticed that, differently than what happened in wild types, plants of domesticated tomatoes promptly reacted to temporary rewatering after suffering a prolonged period of water stress through a fast stomata reopening.…”
