Although cotton can be properly managed in regions with water limitation, its yield is affected at different levels according to the genetics of the cultivar adopted. Exogenous application of some organic components has shown a stress-mitigating effect and can be a valuable procedure to enhance the yield of water stress-sensitive cultivars. The objective of this work was to evaluate the benefits of exogenous application of pyruvic acid (100 \u00b5M) in cotton plants under water deficit varying the phenological stage of the crop. The experiment was conducted in a greenhouse, where the plants were grown in pots and subjected to seven days of water suspension, initiated individually in stages V2 and B1. Each pot contained two plants. The treatments adopted were: T1 - control, T2 - water suppression; and T3 - water suppression + pyruvate application. The design was randomized blocks in a factorial scheme (3 \u00d7 3) with three replicates. The reductions in gas exchange and growth of the cultivars BRS Serid\u00f3, CNPA 7MH and FM 966 were more significant in the reproductive stage, especially for FM 966, which was more sensitive. Pyruvate application reduced the effects of water suppression on boll production by 31% in BRS Serid\u00f3 and 34% in CNPA 7MH and FM 966.<\/jats:p>","DOI":"10.1590\/1519-6984.272003","type":"journal-article","created":{"date-parts":[[2023,5,5]],"date-time":"2023-05-05T11:42:25Z","timestamp":1683286945000},"source":"Crossref","is-referenced-by-count":4,"title":["Pyruvic acid as attenuator of water deficit in cotton plants varying the phenological stage"],"prefix":"10.1590","volume":"83","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4558-1147","authenticated-orcid":false,"given":"F.
