Randomised, Double‐Blinded, Placebo‐Controlled Challenge Test With Single Food Items in Dogs With Atopic Dermatitis and Adverse Food Reactions

Veterinary Dermatology, Volume 37, Issue 2, Page 247-256, April 2026.
ABSTRACT Background Identification of offending foods in dogs with adverse food reactions is usually based on “deterioration” during open food challenges. Objectives To examine the placebo effect during double‐blinded, placebo‐controlled food challenges using a predefined set of criteria for relapse.

Alterations in plant architecture and physiology allow maize to sustain yield after early defoliation

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Maize (Zea mays L.) tolerance to early defoliation is shaped by genotype‐specific physiological and morphological responses. Defoliation disrupts the source–sink balance, altering carbon allocation and plant development. Understanding these responses is crucial for optimizing breeding programs and agronomic management.

Características fisiológicas de biótipos de Conyza bonariensis Resistentes ao glyphosate cultivados sob competição [PDF]

Planta Daninha, 2013
A resistência de plantas daninhas a herbicidas está relacionada a modificações metabólicas, enzimáticas, fisiológicas e/ou anatômicas. Aliado a essas mudanças, a planta pode aumentar ou diminuir as atividades fisiológicas, o que, consequentemente, pode ...

Partitioning between primary and secondary metabolism of carbon allocated to roots in four maize genotypes under water deficit and its effects on productivity

Crop Journal, 2015
Plants may respond to drought by altering biomass allocation to shoots and roots or by changing the metabolic activities in these organs. To determine how drought changes the partitioning of carbon allocated to growth and secondary metabolism in maize ...

Agronomic Characteristics, Chemical Composition, and Digestibility of Different Biomass Sorghum Hybrids

Advances in Agriculture, Volume 2026, Issue 1, 2026.
Biomass sorghum is notable for its high dry matter (DM) yield, making it suitable for silage production. However, hybrids with higher biomass production often show lower nutrient digestibility due to a greater proportion of stems. This study aimed to evaluate the agronomic performance, chemical composition, and fiber digestibility of five biomass ...
