Results showed that GY penalties were primarily driven by the intensity of HW rather than genetic background, as genotypic responses to HW treatments were largely similar. Both genotypes exhibited comparable GY penalties, associated with similar changes in yield components, despite contrasting yield formation strategies. The indirect effects of pre-anthesis (pre-ANT) HW were more pronounced in the genotype relying on average grain weight (AGW; Pistolo), whereas direct effects were more critical in the genotype dependent on grain number (GN; Sublim). Across experiments, HW consistently reduced GY through decreases in GN when applied pre-ANT (but through affecting more grain abortion than floret fertility) and in AGW when applied post-anthesis (post-ANT). When GY penalties were normalised by HW intensity, crops were more sensitive during grain-number determination than during grain filling. Additionally, the interaction between sequential HW events revealed an antagonistic interaction reflecting a \u2018priming\u2019 effect of pre-ANT HW on the penalty imposed by a post-ANT HW. This antagonism highlights the importance of considering multiple heat stress events when predicting yield penalties under future climate scenarios.<\/jats:p>","DOI":"10.1093\/jxb\/erag466","type":"journal-article","created":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T19:27:16Z","timestamp":1789673236000},"source":"Crossref","is-referenced-by-count":0,"title":["Heat waves at pre-anthesis, post-anthesis, and sequentially across both stages on wheat yield under field conditions"],"prefix":"10.1093","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7736-9522","authenticated-orcid":false,"given":"Breno","family":"Bicego","sequence":"first","affiliation":[{"name":"Department of Agricultural and Forest Sciences and Engineering, University of Lleida , Av.
