Leaf Morphoanatomy and Biochemical Variation on Coffee Cultivars Under Drift Simulation of Glyphosate [PDF]

Planta Daninha, 2018
: The most widely used herbicide in coffee crop is glyphosate, it inhibits the biosynthesis of secondary metabolites, responsible for structures and substances of plant defense. This work aimed to evaluate the morphoanatomy, total phenols, flavonoids and

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

Pest Management Science, Volume 82, Issue 6, Page 5757-5766, June 2026.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

Assessment of genetic variability within and among coffee progenies and cultivars using RAPD markers

Genetics and Molecular Biology, 2003
The RAPD technique associated with restriction digestion of genomic DNA was used to assess the genetic variability within and among nine populations of Coffea arabica, including six progenies belonging to the Sarchimor germplasm, the progeny PR 77054-40 ...

Association of Agro‐Morphological Traits With Cup Quality in Accessions of Coffea arabica L. From the INIA Germplasm Bank, Peru

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT In recent years, Peruvian coffee production has increasingly focused on specialty coffees, with cup quality (CQ) as a key criterion. While previous studies have characterized the Coffee Germplasm Collection of the National Institute of Agrarian Innovation (CGC‐INIA), few studies have analyzed coffee cup quality.

Yield, stability, and plasticity of Arabica coffee genotypes under contrasting pruning systems

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Coffee yield instability caused by biennial bearing causes coffee yield instability, reducing production predictability and farm income. Biennial drastic pruning (Zero Crop), which alternates harvest and no‐harvest years, has been proposed to reduce this instability, but its benefits depend on genotype performance under contrasting management.

Thermal sensitivity and yield of Arabica coffee under climatic variability

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Coffee yield is influenced by climatic factors, with temperature and water availability being key determinants. This study aimed to evaluate the effects of climate variability on the yield of Arabica coffee (Coffea arabica L.) cultivars across phenological phases and to validate an agrometeorological model at local and regional scales using ...

Unlocking the Quality Potential of Liberoid Coffee: Advances in Composition, Processing, and Microbial Fermentation

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Liberoid coffee (Coffea liberica group), comprising varieties of Liberica and Excelsa coffee types, is gaining attention for its unique chemical composition and sensory potential. However, its quality remains under‐optimized due to limited understanding of genotype‐specific traits and processing responses.
