Light interception, chemical, and productive characteristics of elephant grass subjected to different cutting intervals

Semina: Ciências Agrárias, 2019
This study aimed to evaluate the interception of light (%IL), leaf area index (LAI), and the chemical and productive characteristics of elephant grass (Pennisetum purpureum Schum) under different defoliation frequencies (30, 45, 60, 75, and 90 days after

Coupled decline in growth and fine‐branching signals the onset of drought‐induced European beech mortality

New Phytologist, EarlyView.
Conceptual synthesis of drought‐induced mortality in European beech. Summary Severe and recurrent droughts have caused widespread canopy decline and mortality in European forests. Drought‐induced mortality occurs when structural damage and physiological dysfunction impair a tree's ability to recover, yet it remains unclear when trees transition from ...

Carbohydrate content governs growth‐storage allocation during recovery from carbon depletion

New Phytologist, EarlyView.
Conceptual framework for competing hypotheses of growth‐storage carbon allocation during recovery from carbon limitation. Summary How plants prioritize carbon (C) allocation between growth and storage remains an outstanding question, limiting predictions of forest C cycling and ecosystem resilience following periods of C limitation. To address this gap,

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

Plant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

Revealing the Key Genetic Basis of Late Leaf Spot Resistance in Peanut by Combining QTL Mapping, QTL‐seq and RNA‐seq

Plant, Cell &Environment, EarlyView.
ABSTRACT Late leaf spot (LLS) is the most widespread and destructive fungal disease affecting peanut worldwide, yet relatively little is known about its genetic basis. In this study, QTL mapping using a 1327‐bin map (derived from 9533 SNP/InDel markers) and multi‐environment phenotypic data repeatedly detected two major LLS‐resistance QTLs on ...

Extreme climatic events, biotic interactions and species-specific responses drive tree crown defoliation and mortality in Italian forests

iForest - Biogeosciences and Forestry
The frequency of forest disturbances has increased in recent years, provoking widespread defoliation, crown dieback and tree mortality. The ICP Forests monitoring network offers a unique platform for observing the impacts on forests of heatwaves ...

Cotton rotation with single and multispecies cover crops affects yield, quality, and economic outcomes

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Cover crops (CCs) have gained popularity in continuous crop production systems due to their agroecosystem benefits. This study evaluated the effects of nine CC treatments (single or multispecies) and no cover crop (noCC) on cotton (Gossypium hirsutum L.) growth characteristics, production, and economic returns in the Mid‐South United States ...
