Abstract
During the last decades, water distribution around the globe has been affected by climate change. Particularly, in Chile, the last decade has been marked by a mega-drought period, which has severely impacted agriculture. In this scenario, common bean (Phaseolus vulgaris L.) has been seriously affected due to its dependence on irrigation. In this work, we studied how 'Zorzal,' the most sown cultivar in Chile copes with drought stress and the mechanisms used to deal with it. A greenhouse experiment was performed during the 2019 2020 growing season. Plants were subjected to a severe drought stress suspending irrigation at the pre-flowering stage. Photosynthetic parameters, chlorophyll concentration, relative leaf water content (RWC) and lipid peroxidation were analyzed at 7 and 21 days after water suspension, yield was analyzed at the end of the growing season, and those parameters were compared to a susceptible cultivar of the same gene pool Arroz Tuscola. Zorzal stood out for having diverse treats associated with drought tolerance, as maintaining stable RWC during drought stress, a better reactive oxygen species scavenging system than Arroz Tuscola, and stable root biomass during the drought condition. However, seed production was significantly reduced. Our results evidence that Zorzal, the most widely cultivated cultivar of common bean in Chile, has good physiological and anatomical treats for plant survivance under drought stress conditions. However, our study suggests that these characteristics may not be enough to maintain a stable seed production. © 2024 Elsevier B.V., All rights reserved.
