Morphophysiological Behavior and Cambial Activity in Seedlings of Two Amazonian Tree Species under Shade

Journal of Botany, Volume 2015, Issue 1, 2015., 2015
Variations in light intensity can lead to important anatomical and morphophysiological changes in plants. Aiming to increase knowledge about the Amazonian tree species, this study examines the influence of shade on the cambial activity and development of Parkia gigantocarpa Ducke and Schizolobium parahyba var.

Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

People and Nature, Volume 8, Issue 6, Page 1943-1956, June 2026.
Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

Cellulose acetate obtained from Schizolobium parahyba (vell.) blake wood

Research, Society and Development, 2021
Currently, non-biodegradable polymers are produced on a large scale and cause several environmental problems, especially due to their low degradation. Cellulose acetate is a non-toxic, low-flammable and low-cost polymer, playing an important environmental role.

Morphometry and seed beneficiation of Schizolobium parahyba (Vell.) Blake var. parahyba

Journal of Biotechnology and Biodiversity, 2020
The objective of this work was to evaluate morphometry and seed beneficiation of Schizolobium parahyba. Were used seeds from the three tree matrices located in a ciliary domain area in the municipality of Medianeira – PR. Casually separated four repetitions from 100 seeds. Circular sieve sieves were used, with perfurations of 14 mm to 18 mm, and oblong
