Assessment of corn chlorophyll content via UAV‐derived vegetative indices across growth stages

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Traditional chlorophyll (Chl) assessment methods are labor‐intensive and spatially limited. This study evaluated unmanned aerial vehicle (UAV) multispectral imagery for nondestructive field‐scale canopy Chl estimation in corn (Zea mays L.) to support precision nutrient management.

Reproduction of Mi-Virulent Meloidogyne incognita Isolates on Lycopersicon spp.

Journal of nematology, 2011
Selection of detectable numbers of Mi-virulent root-knot nematodes has necessitated a greater understanding of nematode responses to new sources of resistance. During the course of this research, we compared the reproduction of four geographically distinct Mi-virulent root-knot nematode isolates on three resistant accessions of Lycopersicon peruvianum.

Aphid Resistance in Pulse Crops: Sources, Mechanisms, Genetics and Breeding

Legume Science, Volume 8, Issue 4, December 2026.
ABSTRACT Aphids are major pests of pulse crops, causing damage through phloem sap feeding and virus transmission. In this context, resistant varieties are central components of sustainable aphid management. This review synthesizes current knowledge on resistance sources, phenotyping strategies, resistance mechanisms, genetic control and breeding ...

Determinants of Crop Diversification in Boro Rice‐Based, Wetland Farming Systems in Bangladesh

Plant-Environment Interactions, Volume 7, Issue 6, December 2026.
Crop diversification in haor areas of Bangladesh remains low and is associated with household, institutional, infrastructural, and agro‐ecological factors. Strengthening farmer socioeconomic factors, institutional access, infrastructure, and adaptation to protracted waterlogging may help greater crop diversification.

Spatial analysis of cell patterning to aid genetic and phenotypic understanding of grass stomatal density: A case study in maize

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Biological processes involve complex hierarchies where composite traits result from multiple component traits. However, holistically understanding of how sets of component traits interact to underpin genotype‐to‐phenotype relationships is generally lacking.

Feeding non-preference by Spodoptera frugiperda and Spodoptera eridania on tomato genotypes

Revista Ceres, 2013
Larvae of the genus Spodoptera spp. are highly polyphagous and can cause economical losses in several agricultural crops. Given their growing importance in the tomato crop, especially for industry, this work aimed to evaluate the feeding non-preference ...

BerryBox: An affordable computer vision system for postharvest phenotyping of cranberry and other small fruits

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Fruit size, shape, color, and percent fruit rot are important quality traits for breeding cranberry (Vaccinium macrocarpon Ait.). Image analysis can be used to measure these traits, but affordable hardware for standardized image capture and integrated user‐friendly software pipelines are lacking.

Geographical proliferation of ongoing novel host use by the herbivorous ladybird beetle Henosepilachna vigintioctopunctata (Coleoptera: Coccinellidae)

Entomological Science, Volume 29, Issue 4, December 2026.
The geographical extent of occurrence of the Solanaceae‐feeding Henosepilachna vigintioctopunctata on the novel fabaceous host Centrosema molle and the ability of larvae from several beetle populations to develop on C. molle were investigated to depict the incipient phase in the speciation continuum of herbivorous ladybird beetles.
