Vegetative and reproductive phenology of Copaifera langsdorffii Desf. in different phytophysiognomies

open access: yesResearch, Society and Development, 2022
The phenology has been discussed according to climatic variations and the environmental characteristics of each physiognomy, trying to identify if there is variation in the vegetative and reproductive phenophases, for Copaifera langsdorffii Desf. in areas of the Cerradão, Carrasco and Humid Forest, Chapada do Araripe in Northeast Brazil and if they are

Genetic diversity and mating system of Copaifera langsdorffii (Leguminosae/Caesalpinioideae)

open access: yesGenetics and Molecular Research, 2013
Copaifera langsdorffii, locally known as copaíba, is a valuable tropical tree with medicinal properties of its oil. We studied the genetic variation, genetic structure, and the mating system of trees in stands of C. langsdorffii (Leguminosae/Caesalpinioideae) located in an extensive area between the Pardo and Mogi-Guaçu basins in São Paulo State ...

Fenologia e artrópodes de Copaifera langsdorffii Desf. no cerrado [PDF]

open access: yesRevista Brasileira de Plantas Medicinais, 2005
There was evaluated the phenology and arthropods as well as the effect of weather on copaiba (Copaifera langsdorffii Desf.) (Leguminoseae). The emission of new leaves and inflorescences as well as the opening of them occurred in the rainy period. There were observed the higher diversity and abundance of insects, principally galling insects.

Shading for water stress mitigation in Copaifera langsdorffii Desf. seedlings

open access: yesSouth African Journal of Botany, 2021
Abstract In this study, we hypothesized that Copaifera langsdorffii Desf. seedlings do not tolerate cultivation under water deficit, but shading could minimize stressor effects of water shortage and enable fast antioxidant responses, maintaining high photosynthetic rates and favoring stressed plant recovery.

Effects of pre-germination treatments on Copaifera langsdorffii seeds

open access: yesAfrican Journal of Agricultural Research, 2016
Copaifera langsdorffii has been intensely exploited, since it attracts several interests, and is now on the list of endangered species. Due to this risk of extinction, seedling production of this species has important economic and social value. The aim of this study was to evaluate seed germination of C.
