“…These studies should examine the genes associated with acceptable CO 2 assimilation in the leaves at high temperatures, and acceptable leaf, flower and fruit growth under the same conditions. Liu et al (2023a) indicated that traditional breeding is not efficient in developing cultivars adapted to warm weather. Genotypes with high photosynthesis will not be more productive under climate change, unless the better gas exchange is associated with better growth and fruiting.…”

Fruit growth in strawberry is dependent on photosynthesis in the leaves. The main scenarios for climate change include an increase in the concentration of CO 2 in the atmosphere and an increase in temperature. This review examined photosynthesis in strawberry. The mean photosynthetic photon flux (PPF) for the saturation of CO 2 assimilation was 1,031 ± 447 µmol per m 2 per s, the median was 1,000 µmol per m 2 per s, and the range was from 467 to 2,200 µmol per m 2 per s (N = 59). The mean concentration of CO 2 for the saturation of assimilation was 869 ± 306 ppm, the median was 900 ppm, and the range was from 410 to 1,750 ppm (N = 32). The optimum temperature range for CO 2 assimilation was 20° to 30°C, with lower photosynthesis at lower or higher temperatures. The optimum temperatures for photosynthesis are higher than those for flowering and fruit growth. The impact of climate change on production varies across growing areas. In warm locations, higher temperatures increase photosynthesis, but not yield. In cool locations, higher temperatures increase plant growth and the length of the production season, but this comes at the expense of flower initiation.

“…Similarly to other plant species, tomato is very sensitive to high ambient temperatures, a globally increasing phenomenon due to climatic changes. For tomato plants, temperatures exceeding 32°C during the day, and 21°C during the night create conditions of heat stress, leading to various physiological and developmental effects that drive dramatic reduction in fruit set and total yield, thus necessitating the identification of novel resources for tomato breeding ( Hazra et al., 2007 ; Liu et al., 2023 ). The negative effect of heat stress on yield is the consequence of multiple molecular, physiological and developmental processes that are hindered by elevated temperatures, underlining tomato thermotolerance a highly complex trait.…”

The occurring temperature increase in crop production areas worldwide is generating conditions of heat stress that negatively affect crop productivity. Tomato (Solanum lycopersicum), a major vegetable crop, is highly susceptible to elevated temperatures. Under such conditions, fruit set is dramatically reduced, leading to significant yield losses. Solanum pimpinellifolium, a wild species closely related to the cultivated tomato, was shown to have beneficial attributes under various abiotic stress growth conditions. We have utilized a new population of backcross inbred lines originated from a cross between S. pimpinellifolium and S. lycopersicum, in order to evaluate its potential as a new genetic resource for improvement of reproductive performance of cultivated tomato under heat stress conditions. This population was screened for various heat stress-related traits, under controlled heat stress and non-stress conditions. Our results show that significant variation exists for all the heat stress related traits that were examined and point at individual lines with better reproductive performance under heat stress conditions that share a common introgression from the wild S. pimpinellifolium parent, suggesting several candidate genes as potential drivers of thermotolerance. Thus, our results place this population as a valuable new resource for the discovery of heat stress related genetic loci for the future development of heat stress tolerant tomato cultivars.
