Rice (Oryza sativa L.) is among the most consumed cereals in the world. Its growth is severely affected by excessive salinity, leading to considerable negative economic impacts. Thus, BRS Esmeralda and S ̃ao Francisco rice cultivars, presenting antagonist cultivation recommendations and differential salt tolerance, were selected to examine how salt stress influences ionic homeostasis and photosynthetic capacity...
The halophyte Salicornia neei Lag. can be used as a phytoremediation agent in salt degraded areas. The objective of this work was to evaluate the organic (carbohydrate and N-aminosoluble) and inorganic (Na+, K+ and Cl-) solutes contents in S. neei submitted to different blades of irrigation and fertilization in Ceara semiarid. The samples were obtained in culture carried out in Ocara-CE. Four areas of 100 m2 we...
Plants are often exposed to abiotic stresses such as salinity, which represents a barrier to the cultivation of agricultural species mainly in arid and semi-arid regions. This study evaluated the development of four saccharine sorghum genotypes for tolerance to different salinity levels under greenhouse conditions. The experimental design was a randomized complete block arranged in a 5 × 4 factorial scheme, whi...
Under salinity stress, plants commonly accumulate carbohydrates for osmotic adjustment to balance the excess accumulated ions and to protect biomolecules. We selected two cowpea cultivars with contrasting response to salinity, Pitiúba (salt-tolerant) and TVu (salt-sensitive), to investigate whether the salt tolerance could be associated with changes in carbohydrate accumulation and metabolism in leaves and root...
The accumulation of salts in the soil is a common problem of arid and semi-arid regions, that cause reduction in plant growth and yield. In this context, the arbuscular mycorrhizal fungi (AMF) have been studied in recent years, with results indicating that their associations with the plant roots minimize some effects of salt stress. The objective of this work was to evaluate the influence of increasing levels o...
This work aimed to evaluate the influence of salt stress exposition on growth and ion accumulation in dwarf cashew plants. For this purpose, cashew nuts (CCP 06 clone) were sown in plastic trays containing vermiculite moistened with nutrient solution containing NaCl with electrical conductivities ranging from 0.0 to 18.0 dS m-1. Plants were harvested after 30 and 60 days under salt stress. It was determined the...
