Little is known about the role of light intensity in modulating plant responses to stress due to water deficit (WD). Thus, the objective of this study was to determine the WD and contrasting irradiance effects on the physiology, anatomy, and grain yield of soybean plants. The experimental design was a randomized block in a growth chamber and a 2 × 2 factorial treatment arrangement: 90% (well‐watered,...
Fluorine is found in the atmosphere mainly in the form of hydrofluoric acid, released by industries linked to the production of aluminum, glass and ceramics, in addition to phosphate fertilizers. It is an element of high toxicity, quite harmful to plant growth. Eugenia dysenterica (Mart.) DC. (Myrtaceae) species is a fruit tree native to the Brazilian Cerrado with wide distribution in anthropic regions...
Aluminum (Al) exposure effects on Hancornia speciosa Gomes were investigated via culture in a nutrient solution containing 0 (control), 300 and 600μmol Al L−1. Seedling emergence, nutrient accumulation, growth and root anatomy were evaluated. Seedling emergence, emergence speed index and root diameter under hydroponic cultivation were significantly reduced in the Al treatments, while Al promoted root...
