Soil drying and rewatering applied at three grain developmental stages affect differentially growth and grain protein deposition in wheat (Triticum aestivum L.) [PDF]

, 2006
Water deficits cause large yield losses in wheat. Although anthesis is generally considered the most vulnerable period, water deficit during grain filling can also cause yield losses.

The Unstable Relationship Between Drought Status and Leaf Water Content Complicates the Remote Sensing of Tree Drought Stress

Global Change Biology, Volume 31, Issue 4, April 2025.
Remote sensing can monitor plant drought stress across ecosystems but is limited by uncertain links between physiological stress and measurements of water content. We examined how water potential and water content, measured in the field, laboratory, and via airborne imaging, vary over time and space in two oak species.

Comportamento de híbridos de milho selecionados e não selecionados para ASI sob estresse de água no florescimento e no enchimento de grãos. [PDF]

, 2018
A seca é um dos principais estresses abióticos que reduzem a produção do milho. Essa redução depende do estádio de desenvolvimento da cultura e da duração do período do estresse de água na planta.

Successful recovery of native plants post‐invasive removal in forest understories is driven by native community features

Ecological Applications, Volume 35, Issue 2, March 2025.
Abstract Temperate forest understories hold the majority of the plant diversity present in these ecosystems and play an essential role in the recruitment and establishment of native trees. However, the long‐term persistence of diverse and functional forest understories is threatened by the impacts of invasive plants.

Estresse e comportamento alimentar

Research, Society and Development, 2021
Introdução: podemos definir como um breve conceito de estresse o entendimento como sequências de reações, que transformam a integridade física e psicológica, que aterrorizam o equilíbrio do organismo (homeostase). O estresse é um fator importante no desenvolvimento do vício e na recaída do vício e pode contribuir para um maior risco de obesidade e ...

Rainfall seasonality shapes belowground root trait dynamics in an Amazonian tropical rainforest: A test of the stress‐dominance hypothesis

Functional Ecology, Volume 39, Issue 3, Page 799-812, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stress‐dominance hypothesis (SDH) predicts that trait variation at the community level increases with the availability of limiting resources, driving spatial and temporal patterns in above‐ground plant functional trait expression.
