Summary: | The use of saline waters in irrigated agriculture has become a reality in several regions of the world. However, this practice may cause limitations to growth and development, depending on the tolerance level of the crop. Applying strategies that minimize salt stress in crops is therefore essential, and, in this respect, salicylic acid can act as an antioxidant and enhance the plant’s tolerance to salt stress. The objective of this study was to examine the effects of foliar application of salicylic acid on the physiology and production components of naturally colored cotton cv. BRS Jade grown under salt stress. The plants were cultivated on lysimeters in outdoor conditions at the Agro-Food Science and Technology Center, Federal University of Campina Grande, located in Pombal - PB, Brazil. The experiment was laid out in a randomized block design with a 5 × 5 factorial arrangement consisting of five irrigation-water electrical conductivity levels (ECw: 0.3, 1.8, 3.3, 4.8, and 6.3 dS m-1) and five concentrations of salicylic acid (SA: 0, 1.5, 3.0, 4.5, and 6.0 mM), with three replicates. Irrigation with water with salinity levels from 0.3 dS m-1 reduced gas exchange, the synthesis of photosynthetic pigments, and the number of bolls in cotton cv. BRS Jade. Salinity levels from 0.3 dS m-1 induced stomatal closure and reduced transpiration, CO2 assimilation rate, the levels of photosynthetic pigments, and production components of cotton cv. BRS Jade. The salicylic acid concentrations of 2.6 and 2.7 mM increased CO2 assimilation rate and stomatal conductance, respectively, in the cotton plants. Foliar application of salicylic acid did not mitigate the effects of salt stress on gas exchange, the synthesis of photosynthetic pigments, or production components of cotton. |

Dessa forma, o uso das estratégias que minimizem o estresse salino nas culturas é fundamental, nesta perspectiva, o ácido salicílico pode atuar como antioxidante e contribuir na tolerância das plantas ao estresse salino. Neste sentido, objetivou-se avaliar os efeitos da aplicação foliar de ácido salicílico na fisiologia e nos componentes de produção do algodoeiro naturalmente colorido cv. BRS Jade cultivado sob estresse salino. As plantas foram conduzidas em lisímetros sob condições de céu aberto, no Centro de Ciências e Tecnologia Agroalimentar pertencente à Universidade Federal de Campina Grande, Pombal-PB. O delineamento utilizado foi em blocos casualizados, em esquema fatorial 5 × 5, sendo cinco níveis de condutividade elétrica da água de irrigação - CEa (0,3; 1,8; 3,3; 4,8 e 6,3 dS m-1) e cinco concentrações de ácido salicílico - AS (0; 1,5; 3,0, 4,5 e 6,0 mM) com três repetições. A irrigação com água a partir de 0,3 dS m-1 reduziu as trocas gasosas, a síntese de pigmentos fotossintéticos e o número de capulhos do algodoeiro cv. BRS Jade. A irrigação com água a partir de 0,3 dS m-1 induziu o fechamento estomático e diminuiu a transpiração, a taxa de assimilação de CO2, os teores de pigmentos fotossintéticos e os componentes de produção do algodoeiro cv. BRS Jade. As concentrações de ácido salicílico de 2,6 e 2,7 mM proporcionaram aumento na taxa de assimilação de CO2 e condutância estomática, respectivamente, das plantas de algodão. A aplicação foliar de ácido salicílico não amenizou os efeitos do estresse salino sobre as trocas gasosas, a síntese de pigmentos fotossintéticos e os componentes de produção do algodoeiro.UEL2023-03-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4500110.5433/1679-0359.2023v44n1p147Semina: Ciências Agrárias; Vol. 44 No. 1 (2023); 147-170Semina: Ciências Agrárias; v. 44 n. 1 (2023); 147-1701679-03591676-546Xreponame:Semina.
