IndexGrowing a tomatoPlant for experimentsEffects of heat stress on tomatoGrowing a tomatoAfter the potato, the tomato (Lycopersicon esculentum) is considered the most valuable vegetable crop grown globally. While the net acreage on which tomatoes are grown has remained the same, production has increased significantly over the last decade. Currently, around 200 million tonnes of tomatoes are produced on sites spanning a total of 3.7 million hectares. China, United States, India and Türkiye are the main tomato producing countries. While Belgium (4,996,000 Hg/ha) and the Netherlands (4,835,973 Hg/ha) have the highest fruit yield per hectare. Say no to plagiarism.

Climate change and a growing global population have created an unstable agricultural sector and imminent pressure on food security. The agricultural sector is obsessed with increasing production and improving the health of crop varieties through the application of good animal husbandry and scientific solutions. Many researchers, such as Ainsworth and Ort (2010), have predicted yield deficits due to climate change. Plant for experiments In addition to being an economically and nutritionally important crop globally, the tomato has many characteristics that make it an ideal model plant species for experiments. It has well-documented genetic information and has a short reproductive period. Although Arabidopsis thaliana is the standard plant model, several developmental traits are present in tomato that are not present in A. thaliana such as; photoperiod-independent sympodal flowering, climate-dependent fruit formation, compound leaves, mycorrhizal roots and glandular trichomes. Furthermore, there are numerous varieties of cultivars on the market that can satisfy a wide range of research such as the dwarf cultivar Micro Tom (. Effects of heat stress on tomatoes. Reproductive development tends to be influenced more by high temperatures than vegetative development in almost all crops Even slight increases in temperature can impact fruit yield, therefore, decreases are not only related to periods of extreme heat stress. Female reproductive organs have been found to be more resistant to such periods than their male counterparts temperatures of 26/20°C can alter the development of tomato fruits while higher temperatures of 38/27°C during the day/night can cause fruit abortion. Losses of up to 70% can be observed in the affected areas summers with unusually high temperatures induced in fruit set may be linked to damage during the development of reproductive tissues, an imbalance of plant hormones and reduced photosynthetic parameters. Photosynthetic mechanisms that can be damaged include the ratio of chlorophyll and carotenoid levels, hydraulic forces that transport nutrients and water around the plant architecture. One of the major hormones and stress regulators that increase due to suboptimal conditions is abscisic acid (ABA). Stress response genes appear to be upregulated as a signaling response by ABA in order to induce stress tolerance, while ABA also provides feedback information for sugar signaling pathways. Singh and Sawhney (1998) observed the correlation between abnormal developments in the anther and increase..
