Growth and gas exchange of Tachigali vulgaris submitted to water deficiency
Tachigali vulgaris L.G. Silva & H.C. Lima is a pioneer species, colonizer of marginal lands and road margins, which often initiates secondary succession in open areas by the intense germination ofExpand
Gas exchange and carbon metabolism in leaves of crabwood ('Carapa guianensis' Aubl.) in three mechanisms and suspension of water stress
Crabwood or Andiroba (in Brazil) is an arboreal species with variations in their physiological processes from soil and climatic conditions induced, such as lack or excess water. The objective of thisExpand
Trace Elements and Radionuclides in Brazil Nuts from the Brazilian Amazon
The Brazil nut tree ( Bertholletia excelsa ) is an accumulating plant and, as such, absorbs metals from the soil according to the different geographic regions in which it is found. In this context,Expand
Biochemical and physiological responses of andiroba (Carapa guianensis Aubl.) seedlings subjected to water deficit
