Management of Heat Stress in Tomato Seedlings under Arid and Semi-Arid Regions: A Review

Abstract

T HE production of protected cultivation of vegetables could be considered as a sustainable solution in arid and semi-arid regions.These regions already suffer from raising temperature andthe global warmingwill aggravate this, whichrepresents a great challenge facing our universe nowadays. Hence, the production of vegetables and tomato under greenhouse system during the high temperatures may be considered a serious problem should be avoided in these arid zonesin summer due to heat stress.The heat stress may cause a lot of troubles for the tomato seedlings in greenhouses in summer starting with the photosynthetic rate, and the metabolism processes in seedlings and in turn the growth and development of these seedlings. Although studies have recognized heat stress on tomato seedlings, research has yet to systematically investigate the effect of heat stress on tomato seedlings in greenhouse in summer under arid and semi-arid regions particularly in developing countries, which their greenhouses have not any climate controllers. Therefore, the management of tomato seedlings may need to address the production problems caused by heat stress in greenhouse conditions particularly in arid and semi-arid zones

Developing future heat-resilient vegetable crops

“…As it largely determines the growth and productivity of vegetables. However, under HS, leaves trap higher light energy that damages the photosynthetic machinery and reduces the photosynthetic rate (Abdalla et al 2020). It is considered as the first sensor of environmental stress that initiates imbalanced cellular energy as observed in the altered redox chemistry related to the thylakoid membrane.…”

Physiological Effects of High Temperature Treatments on Tomato Leaves at Two Developmental Phases

“…Tomato (Solanum lycopersicum) is an important vegetable crop all over the world. The optimum range of daytime temperatures for tomato seedlings growth, ranges from 18 to 30°C, with an upper limit of 35°C (Abdalla et al, 2020). On the other hand, the optimum temperature during tomato plant flowering and fruit growth, ranges from 18 to 25°C (Tonhati et al, 2020).…”

Anatomical Changes of Cultivated Plants under Combined Stress: An Urgent Need for Investigation

“…Cultivated plants face generally during their growth environmental stresses including abiotic and biotic stress (El-Ramady et al 2019). These stresses include drought, salinity (Akcin et al 2017), waterlogging Tian et al 2021), high or low temperatures, high or low light, flooding, deficient or excess nutrients (Adejumo et al 2020) and heavy metals (Abdalla et al 2020;Stavridou et al 2021;Seleiman et al 2021). Several studies have been focused on the single or individual stress as a simple study but recently increasing concerns on combined stress have reported like drought and heat stress (Duc et al 2018;Parvathi et al 2020;Li et al 2021;Stavridou et al 2021), salinity and heat stress (Bayoumi et al 2021;Shalaby et al 2021), salinity and nutrient stress (Chrysargyris et al 2019;Pandey et al 2019), drought and pathogen infection (Dixit et al 2019;Gupta et al 2020), drought and element stress (Naz et al 2021), salinity and waterlogging stress (Duan et al 2018;Gill et al 2019;Cheng et al 2021), etc.…”
