As a result of climate change, temperate regions are facing the simultaneous increase in water and heat stress. These changes may affect interactions between plants pollinators, which will have an impact on entomophilous crop yields. Here, we investigated consequences high temperatures stress plant growth, floral biology, flower-reward production, insect visitation five varieties common buckwheat (Fagopyrum esculentum), growing interest for sustainable agriculture. The were grown under two temperature regimes (21 °C/19 °C 28 °C/26 °C, day/night) watering (well-watered water-stressed). Our results showed that reproductive growth was more affected by drought than vegetative combined had detrimental effects. However, variety-dependent. Drought and/or reduced number open flowers per plant, as well resources (nectar pollen), resulting decrease pollinator visits, mainly Although proportion Hymenoptera visiting decreased with temperatures, Diptera remained stable. behavior not strongly temperatures.

The rising atmospheric [CO2] levels will increase global temperature and drought events, threatening wheat (Triticum aestivum) production. In recent years, buckwheat (Fagopyrum esculentum) has emerged as an alternative crop to under extreme drought. However, it is essential understand the ability of these species withstand future climatic conditions where high occur simultaneously in a environment. Since mitigating effect strongly influenced by severity stress, we compared response buckwheat, differently sensitive drought, scenarios. wheat, passively decreased water potential, shown higher dehydration.
