Phytotoxic Effects of Ethanolic Extracts of Magonia pubescens A.St.‐Hil. (Sapindaceae) on the Germination of Emilia sonchifolia (L.) DC. Seeds

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Ethanolic extracts from Magonia pubescens exhibit concentration‐dependent allelopathic activity against Emilia sonchifolia. Leaf extracts strongly inhibit seed germination and seedling growth, surpassing glyphosate under the tested conditions, whereas intermediate concentrations stimulate germination, indicating hormesis.

Competition Between Grasses and Khaya ivorensis A. Chev. During Initial Growth: Physiological and Nutritional Aspects

Plant Species Biology, Volume 41, Issue 5, September 2026.
Coexistence with weeds negatively affects growth, physiological, and nutritional variables of K. ivorensis in the initial phase of development. Coexistence with M. maximus is more harmful to the development of K. ivorensis seedlings compared to other grasses studied.

Air-drying of seven clones of Eucalyptus grandis × Eucalyptus urophylla wood

BioResources, 2019
Selecting clones with the best genetic material is one goal of eucalyptus breeding programs. Understanding the variations between the wood from different hybrid clones during drying is necessary to process improvement. This study aimed to select eucalyptus clones for lumber production based on their drying defects. From a plantation in Brazil, 42 trees

Forage Responses and Beef Cattle Performance in Silvopasture Systems: A Meta‐Analysis of Tropical and Subtropical Regions of Brazil

Grass and Forage Science, Volume 81, Issue 3, July-September 2026.
ABSTRACT Silvopasture systems integrate tree, forage, and livestock components, offering a sustainable intensification strategy that combines environmental and productive benefits, although shading may impose constraints on forage accumulation. This study aimed to evaluate forage accumulation, nutritive value, and beef cattle performance in pastoral ...

RELATIONSHIP BETWEEN THE ANATOMY AND DRYING IN Eucalyptus grandis X Eucalyptus urophylla WOOD [PDF]

Revista Árvore, 2016
ABSTRACT Drying is an important step to using wood and anatomical characteristics influence this process. Thus, the objective of this work was to evaluate the relationship between anatomy and wood drying. Samples with 2 x 2 x 4 cm were obtained from eight Eucalyptus urophylla x Eucalyptus grandis clones at 1.3 m height to evaluate the anatomy and ...
