Dissertação (Mestrado em Ciências Ambientais) - Universidade Federal de Alfenas, Alfenas, MG, 2022.https://repositorio.unifal-mg.edu.br/handle/123456789/2017The corn crop is one of the main crops affected by the lack of water, which causes changes in its metabolism, development, reproduction, reflecting on its productivity. Within this scenario, the single hybrid BRS 1030®, created by EMBRAPA MILHO and SORGO presents excellent productivity and production stability in environments above and below 700 meters of altitude, but sensitive to water stress. This hybrid is demanding for high-tech crops, mainly to protect against attacks by common pathogens, such as aphids, bacteria that cause stunt, among others. In this sense, this hybrid exposed to water stress was analyzed, receiving treatments based on semisynthetics of trehalose and trehalose and their derivatives with the aim of mitigating the stress. For further quantitative analysis of the production of primary metabolites. Where it was possible to observe the beneficial results, that is, trehalose helped the production and maintenance of primary metabolites, with a view to cellular protection of the plant exposed to stress in the phases evaluated.application/pdfAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/MilhoInibidorEstresse hídricoOUTROSDissertaçãoSantos Filho, Plinio Rodrigues Dos
