Influence of chromium and sodium on development, physiology, and anatomy of Conilon coffee seedlings.

Some components found in the composition of the tannery sludge are nutrients for the plants; it can be considered an alternative source of fertilization as they have favorable agronomic characteristics. However, it is reported in some studies that the presence of chromium and sodium in this residue causes physiological and anatomical disturbances that inhibit the development of the plants. The objective of this study was to evaluate the influence of chromium and sodium on the physiology, anatomy, and development of Conilon coffee seedlings grown on substrates produced with tannery sludge and equivalent doses of chromium and sodium.

Biomass and Leaf Acclimations to Ultraviolet Solar Radiation in Juvenile Plants of and .

Despite the negative impacts of increased ultraviolet radiation intensity on plants, these organisms continue to grow and produce under the increased environmental UV levels. We hypothesized that ambient UV intensity can generate acclimations in plant growth, leaf morphology, and photochemical functioning in modern genotypes of and . Coffee plants were cultivated for six months in a mini greenhouse under either near ambient (UVam) or reduced (UVre) ultraviolet regimes.

Data on leaf structural, physiological and nutritional characteristics of species co-occurring in restinga and semidecidual seasonal forest ecosystems.

This paper presents additional data on the leaf structural, physiological and nutritional characteristics of three species ( e ), co-occurring in restinga and semideciduous seasonal forest (forest). The data of the leaf structural, physiological and nutritional characteristics were obtained from the three species to identify possible adaptive strategies that could explain the co-occurrence of these species in the restinga and forest. In addition, this data can help identify key functional traits in the plant community of restinga and forests that can be employed in the reestablishment of ecological and edaphic processes in these ecosystems.
