Última Quantum efficiency of photosystem II and production of orange under salt stress and nitrogen fertilization AGRIAMBI Sousa,Jônatas R. M. de; Gheyi,Hans R.; Brito,Marcos E. B.; Lacerda,Claudivan F. de; Silva,Francisco V. da; Soares,Frederico A. L.. ABSTRACT This study aimed to evaluate the salt tolerance of 'Mimo do Céu' orange grafted onto three rootstocks using physiological parameters such as maximum quantum efficiency of photosystem II (PSII) and the production of fruits. It also evaluated the effectiveness of increased nitrogen (N) fertilization in reducing the effects of salt stress. Two concomitant experiments were carried out under controlled conditions, using drainage lysimeters. The Experiment I evaluated the effects of the application of five levels of saline water on three combinations of scion-rootstocks grafted with 'Mimo de Ceu' orange, in a randomized block design with three replicates in a 5 x 3 factorial scheme. The Experiment II evaluated the application of two N levels (100 and... Tipo: Info:eu-repo/semantics/article Palavras-chave: Citrus spp.; Physiology; Salt stress..

Agrar.Paran. / SAP Oliveira, Bruno Leminski Neto de; Steiner, Fábio; Honda, Guilherme Bento; Machado, Juan Sotta. Soil salinity is one of the major abiotic stresses that limit seed germination and plant growth, causing yield loss in crop species. The phytotoxic effects of salt stress on seed germination and early growth of physic nut (Jatropha curcas L.) seedlings were investigated in the present study. Physic nut seeds were subjected to five levels of salinity [0 (control); 25; 50; 75 and 100 mmol L-1 of NaCl], using the solution-paper method, with five replications. The experimental unit consisted in a germitest paper roll with 25 physic nut seeds. Salt treatments were evaluated based on the following tests: first count of germination test (7 days), total germination (12 days) and early growth of physic nut seedlings (12 days). Results showed that the addition of... Tipo: Info:eu-repo/semantics/article Palavras-chave: Jatropha curcas; Osmotic stress; Salt stress..
