The study was carried out at the laboratory and greenhouse level, using a Complete Random Design (DCA) with ten treatments and three repetitions, which consisted of 5 doses of EMS (0.00%, 0.25%, 0.50%, 0.75% and 1.00%). for 2 impregnation times (24 and 48 hours). According to the results, the doses of ethyl meta-sulfonate (EMS) influenced the setting of the stolons of the janeiro grass, presenting a high rate of deflation in doses higher than 0.50%. Treatments with doses of 0.25% EMS at 48 hours achieved the best agronomic performance up to 95 days, where plant height had its best development with use close to that determined as DL50 (0.32%). The janeiro grass impregnated with EMS presented slight damage caused by the spittle.","PeriodicalId":54470,"journal":{"name":"Revista De La Facultad De Agronomia De La Universidad Del Zulia","volume":"306 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79841356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
