Germination is a crucial aspect in the life phase of weeds. <i>Phalaris brachystachys</i> biotypes resistant to ACCase-inhibiting herbicides have been confirmed in wheat fields in Iran. This study aimed to investigate the germination behaviour of ACCase- resistant and susceptible subpopulations <i>P. brachystachys</i> under different environmental factors. An analysis of the seed germination of <i>P. brachystachys</i> sub populations at the seed stage was therefore conducted. The resistant (R) and susceptible (S) <i>P. brachystachys</i> subpopulation germination traits were tested in different temperature, salinity stress, drought, and burial depth conditions. All tests were carried out with five replications in a completely randomized design. The highest germination percentage in both subpopulations occurred at a temperature range of 20 to 25 °C. At 35 °C, no germination occurred. In terms of estimated cardinal temperatures, no differences were observed between S and R subpopulations. Seeds containing the ACCase Ile-1781-Thr mutation germinated better under salt and osmotic stress. There were no fitness differences in pH conditions. The percentage and rate of emergence of the R subpopulation were more than S subpopulation at different burial depths. The seedling emergence reached a maximum of 50% in the S subpopulation at a depth of 6.65 cm and in the R subpopulation at depths of 9.81 cm, respectively. Significant differences in seed germination were found between herbicide-resistant and susceptible sub population, and the pleiotropic effect of resistant alleles on germination and seed emergence under different environmental conditions was demonstrated. Results suggested that deep tillage operations and the delayed sowing of autumn-sown crops could control resistant populations that emerge more rapidly than S population; therefore, the prevalence in the R population may decrease.</p></div>","PeriodicalId":6973,"journal":{"name":"Acta Physiologiae Plantarum","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138716144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
