Acclimation to short-term low temperatures in two Eucalyptus globulus clones with contrasting drought resistance
(Tree Physiology, 2009-01-01) [Artigo]
We tested the hypothesis that Eucalyptus globulus Labill. genotypes that are more resistant to dry environments might also exhibit higher cold tolerances than drought-sensitive plants. The effect of low temperatures was ...
Effects of sex and altitude on nutrient, and carbon and nitrogen stable isotope composition of the endangered shrub Baccharis concinna GM Barroso (Asteraceae)
(Acta Botanica Brasilica, 2017-04-01) [Artigo]
Previous ecological studies of dioecious plant species have found that female plants preferentially occur at lower altitudes where there are typically better nutritional conditions, while male plants often occur in less ...
Potential of calcium silicate to mitigate water deficiency in maize
(Bragantia, 2016-07-01) [Artigo]
The aim of this study was to evaluate the potential of calcium silicate to mitigate the effects of water deficiency in maize plants yield. A completely randomized factorial design, consisting of five combinations of calcium ...
Photosynthetic pigments, nitrogen status, and flower behavior in eggplant exposed to different sources and levels of potassium
(Scientific Research and Essays, 2012) [Artigo]
The aim of this study was to investigate (i) the influence of different sources and levels of potassium on photosynthetic pigments, (ii) measure nitrogen status in leaf, (iii) evaluate flower behavior in eggplant (Solanum ...
Changes in leaf proline and fruit production induced by potassium stress in eggplant
(Journal of Food, Agriculture and Environment, 2011-04-01) [Artigo]
The aim of this study was to investigate (i) the influence of potassium stress through two potassium fertilizer (KCl and K(2)SO(4)) treatments over leaf proline and fruit production in eggplant, as well as (ii) the ...
Effect of potassium sources on the antioxidant activity of eggplant
(Revista Brasileira de Ciência do Solo, 2014-11-01) [Artigo]
Potassium participates in the essential processes in plant physiology, however, the effects of K sources on plant metabolism have been little studied. Also, in certain cases, K sources and concentrations may cause undesirable ...
