Resumo: Salinity is among the biggest challenges of irrigated agriculture, as it induces several limitations to the growth and physiology of plants; therefore, strategies should be sought that minimize its impacts on plants. In this scenario, the present study was developed to examine the effects of different salicylic acid (SA) application methods on photosynthetic pigments, chlorophyll a fluorescence, gas exchange, and biomass accumulation of cherry tomato under salt stress. The study was carried out in a greenhouse, using a Regosol soil (Psamments) with a sandy-loam texture. The treatments were distributed in a completely randomized design, in a 2 × 4 factorial arrangement consisting of two levels of electrical conductivity in the irrigation water (0.6 or 2.6 dS m-1) and four salicylic acid application methods (M1 = without SA [control] application; M2 = foliar spray; M3 = irrigation; or M4 = spray and irrigation), with five replicates. Irrigation with 2.6 dS m-1 salinity water negatively affected chlorophyll a fluorescence and the total chlorophyll, chlorophyll a, and carotenoid contents, in addition to inhibiting stem dry biomass production and root/shoot ratio. Foliar spray with salicylic acid minimized the deleterious effects of salt stress on gas exchange and chlorophyll content and increased leaf and root dry biomass accumulation and the root/shoot ratio of cherry tomatoes at 120 days after sowing.

Neste contexto, objetivou-se avaliar os efeitos de diferentes métodos de aplicação de ácido salicílico sobre os pigmentos fotossintéticos, a fluorescência da clorofila a, as trocas gasosas e o acúmulo de fitomassa de tomate cereja sob estresse salino. O estudo foi conduzido em casa de vegetação, utilizando-se um Neossolo Regolítico Psamitico de textura franco-arenosa. Os tratamentos foram distribuídos em delineamento inteiramente casualizados, em arranjo fatorial 2 × 4, sendo dois níveis de condutividade elétrica da água de irrigação (0,6 e 2,6 dS m-1) e quatro métodos de aplicação de ácido salicílico (M1= Testemunha - sem aplicação de AS, M2= via pulverização, M3= via irrigação e M4= pulverização e irrigação), com cinco repetições. A irrigação com água de 2,6 dS m-1 afetou de forma negativa a fluorescência da clorofila a, os teores de clorofila a, total e carotenóides, além de inibir a produção de fitomassa seca de caule e a relação raiz/parte aérea. O método de aplicação de ácido salicílico via pulverização foliar minimizou os efeitos deletérios do estresse salino sobre as trocas gasosas e teores de clorofila b e proporcionou maior acúmulo de fitomassa seca de folha e raiz, aumentando também a relação raiz/parte aérea de tomate cereja, aos 120 dias após a semeadura.UEL2022-03-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4329910.5433/1679-0359.2022v43n3p1145Semina: Ciências Agrárias; Vol. 43 No. 3 (2022); 1145-1166Semina: Ciências Agrárias; v. 43 n. 3 (2022); 1145-11661679-03591676-546Xreponame:Semina.
