Induction of salt stress tolerance in cherry tomatoes under different salicylic...
Silva, André Alisson Rodrigues da; Veloso, Luana Lucas de Sá Almeida; Lima, Geovani Soares de; Soares, Lauriane Almeida dos AnjosSalinity 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, a...

Chloroplast pigments and photochemical efficiency of West Indian cherry under s...
Dias, Adaan Sudario; Lima, Geovani Soares de; Gheyi, Hans Raj; Furtado, Guilherme de Freitas; Soares, Lauriane Almeida dos Anjos; Nobre, Reginaldo GomesThe objective of this study was to evaluate chloroplast pigments and photochemical efficiency of West Indian cherry cv. BRS 366 Jaburu as a function of irrigation water salinity and potassium-phosphorus fertilization combinations in the second year of cultivation. The experiment was carried out in a protected environment in Campina Grande, Brazil. Treatments were distributed in randomized blocks, in a 5 × 4 fac...
Gas exchange, growth, and quality of passion fruit seedlings cultivated with sa...
Lima, Geovani Soares de; Andrade, José Nathanael Ferreira de; Medeiros, Mizael Nabor Vaz de; Soares, Lauriane Almeida dos Anjos; Gheyi, Hans RajThis study was conducted to evaluate the gas exchange, growth, and quality of passion fruit cultivars under irrigation with waters of different salinity levels. The experiment was conducted in a greenhouse, in Pombal-PB, Brazil, using a randomized block design in a 5 ? 2 factorial arrangement, with five levels of electrical conductivity of irrigation water (0.3, 1.1, 1.9, 2.7, and 3.5 dS m-1) and two passion fr...
Cell damage, gas exchange, and growth of Annona squamosa L. under saline water ...
Fernandes, Eliene Araújo; Soares, Lauriane Almeida dos Anjos; Lima, Geovani Soares de; Silva Neta, Alzira Maria de Sousa; Roque, Iara AlmeidaThe semi-arid region of Northeastern Brazil has water limitations in terms of both quantity and quality, with salt stress as a limiting factor for increasing yield in most crops. In this context, the present study aimed to evaluate cell damage, gas exchange, and growth of custard apple under salt stress and potassium fertilization. The research was carried out at the Experimental Farm of CCTA/UFCG, in São Domin...
Growth, photosynthetic pigments, and photochemical efficiency of sour passion f...
Paiva, Francisco Jean da Silva; Lima, Geovani Soares de; Lima, Vera Lúcia Antunes de; Ramos, Jailton Garcia; Gheyi, Hans RajThe objective of this study was to evaluate the growth, photosynthetic pigments, and photochemical efficiency of sour passion fruit cv. BRS Rubi do Cerrado irrigated with waters of different cationic natures. The experiment was carried out from March 2019 to January 2020 in a protected environment belonging to the Academic Unit of Agricultural Engineering of the Federal University of Campina Grande (UFCG), Camp...
Foliar application of H2O2 as salt stress attenuator in ‘BRS Rubi do Cerrado’ s...
Ramos, Jailton Garcia; Lima, Geovani Soares de; Lima, Vera Lucia Antunes de; Paiva, Francisco Jean da Silva; Nunes, Kheila GomesIrrigation with saline water causes a reduction in yield, especially in semi-arid regions. Cultivation strategies have been developed to mitigate salt stress on plants, such as the use of hydrogen peroxide. The objective of this study was to evaluate the attenuating effect of hydrogen peroxide on the gas exchange and growth of ‘BRS Rubi do Cerrado’ sour passion fruit cultivated under irrigation with saline wate...
Gas exchange, growth, and production of mini-watermelon under saline water irri...
Lima, Geovani Soares de; Félix, Charles Macedo; Silva, Saulo Soares da; Soares, Lauriane Almeida dos Anjos; Gheyi, Hans RajIn the semi-arid region of northeastern Brazil, due to the occurrence of excess salts, both in the water and soil, plants are constantly exposed to various conditions of abiotic stress. Thus, it is extremely important to identify methods capable of minimizing the effects of salt stress on plants as a way to ensure the expansion of irrigated areas. In this context, the objective of this study was to evaluate the...
Ecophysiology of west indian cherry irrigated with saline water under phosphoru...
Sá, Francisco Vanies da Silva; Gheyi, Hans Raj; Lima, Geovani Soares de; Paiva, Emanoela Pereira de; Silva, Luderlândio de AndradeThe quantitative and qualitative scarcity of water resources is a frequent problem in the semi-arid region of the Brazilian Northeast. The availability of water for irrigation with high salts contents is common, affecting the growth and development of the crops. Thus, it is necessary to adopt strategies that allow the establishment of irrigated cultivation in this region. The objective of this work was to evalu...
Growth and physiology of Annona squamosa L. under different irrigation depths a...
Moreira, Rômulo Carantino Lucena; Brito, Marcos Eric Barbosa; Fernandes, Pedro Dantas; Sá, Francisco Vanies da Silva; Silva, Luderlândio de AndradeThis study aimed to evaluate the growth and physiology of Annona squamosa seedlings under increasing irrigation depths and phosphorus doses. The experiment was conducted in protected environment, evaluating five irrigation depths and four P2O5- doses, arranged in 5 x 4 factorial scheme, in randomized blocks, with four replicates and one plant per plot. Treatments were irrigation depths of 60, 80, 100, 120 and 1...
