Leaf area estimation from linear measurements in different ages of Crotalaria juncea plants

Rapid estimation of sunflower leaf area from linear measurements

Leaf area index measurements

Leaf area index (LAI) is a key structural characteristic of forest ecosystems because of the role of green leaves in controlling many biological and physical processes in plant canopies. Accurate LA1 estimates are required in studies of ecophysiology, atmosphere-ecosystem interactions, and global change. The objective of this paper is to evaluate LA1 values obtained by several research teams us...

Nitrogen fertilization of coffee: organic compost and Crotalaria juncea L

A resposta do cafeeiro aos adubos orgânicos é pouco estudada e, por isso, objetivou-se, neste trabalho, avaliar o efeito de diferentes doses de composto e de Crotalaria juncea L. sobre o crescimento, a produção e a nutrição nitrogenada dos cafeeiros. Os tratamentos foram: composto orgânico, nas doses de 25, 50, 75 e 100% da adubação recomendada, com ou sem a parte aérea de C. juncea. A C. junce...

Convergence in leaf size versus twig leaf area scaling: do plants optimize leaf area partitioning?

BACKGROUND AND AIMS Corner's rule states that thicker twigs bear larger leaves. The exact nature of this relationship and why it should occur has been the subject of numerous studies. It is obvious that thicker twigs should support greater total leaf area ([Formula: see text]) for hydraulical and mechanical reasons. But it is not obvious why mean leaf size ([Formula: see text]) should scale pos...

Anti-inflammatory and Anti-ulcerogenic effect of Crotalaria juncea Linn. in albino rats.

Crotalaria juncea (Leguminoceae) has been used for its antiarthritic effect in the folklore medicine. The purpose of this study was investigating experimentally the possible antiarthritic and antiulcerogenic properties of Crotalaria juncea leaves in animal model. Ethanolic extract of Crotalaria juncea (CJE) was administered at the doses of 200 and 400 mg/kg to complete Freund’s adjuvant (...
