Resumo: | Sour passion fruit is a fruit crop widely cultivated throughout Brazil, due to its adaptation to the tropical climate. However, in semi-arid regions its development is limited by the high concentration of soluble salts in the waters commonly used in irrigation. In this context, exogenous application of low concentrations of hydrogen peroxide can attenuate the damage caused by salt stress. The objective of this study was to evaluate electrolyte leakage, photosynthetic pigments and photochemical efficiency in sour passion fruit cv. BRS Rubi do Cerrado under irrigation with saline waters and foliar application of hydrogen peroxide. A completely randomized design was used, with treatments arranged in split plots, corresponding to five levels of irrigation water salinity - ECw (0.6; 1.2; 1.8; 2.4 and 3.0 dS m-1) and four concentrations of hydrogen peroxide - H2O2 (0; 15; 30 and 45 μM of H2O2) in plots and subplots, respectively. Irrigation with saline water reduced chlorophyll a and total chlorophyll contents of sour passion fruit plants cv. BRS Rubi do Cerrado, at 240 days after transplanting. Hydrogen peroxide at concentration of 15 μM stimulated chlorophyll a and total chlorophyll biosynthesis and, at 45 μM, relieved the effect of 3.0 dS m-1 water salinity on electrolyte leakage in the leaf blade of sour passion fruit. Salt stress did not affect the initial, maximum, variable fluorescence and quantum efficiency of photosystem II of sour passion fruit cv. BRS Rubi do Cerrado. |

O maracujazeiro-azedo é uma fruteira amplamente cultivada em todo Brasil, devido sua adaptação ao clima tropical. No entanto, em regiões semiáridas seu desenvolvimento é limitado devido água alta concentração de sais solúveis nas águas comumente utilizadas na irrigação. Neste contexto, a aplicação de baixas concentrações de peróxido de hidrogênio de forma exógena pode atenuar os danos provocados pelo estresse salino. Objetivou-se com esta pesquisa avaliar o extravasamento de eletrólitos, os pigmentos fotossintéticos e a eficiência fotoquímica em maracujazeiro-azedo cv. BRS Rubi do Cerrado sob irrigação com águas salinas e aplicação foliar de peróxido de hidrogênio. Foi utilizado o delineamento inteiramente casualizados, com os tratamentos dispostos em parcelas subdivididas, sendo cinco níveis de salinidade da água de irrigação - CEa (0,6; 1,2; 1,8; 2,4 e 3,0 dS m-1) e quatro concentrações de peróxido de hidrogênio - H2O2 (0; 15; 30 e 45 µM de H2O2) nas parcelas e subparcelas, respectivamente. A irrigação com água salina reduziu os teores de clorofila a e total das plantas de maracujazeiro-azedo cv. BRS Rubi do Cerrado, aos 240 dias após o transplantio. O peróxido de hidrogênio na concentração de 15 µM estimulou a biossíntese de clorofila a e total e de 45 µM aliviou o efeito da salinidade da água de 3,0 dS m-1 sobre o extravasamento de eletrólitos no limbo foliar do maracujazeiro-azedo. O estresse salino não afetou a fluorescência inicial, máxima, variável e eficiência quântica do fotossistema II do maracujazeiro-azedo cv. BRS Rubi do Cerrado.
