Abstract Multispectral three‐dimensional (3D) imaging offers substantial potential for plant phenotyping, yet manual segmentation of plant organs remains a bottleneck in breeding programs. We developed a color‐based filtering workflow for faba bean (Vicia faba L.) point clouds that optimizes lower and upper thresholds of spectral indices and broadband ...

ABSTRACT The common bean is vital for food security, but its productivity is often limited by competition with weeds, requiring the use of herbicides. The response of genotypes to herbicides such as fomesafen and imazamox is variable, and the traditional evaluation of phytotoxicity through visual methods is subjective.

ABSTRACT Rising global temperatures increasingly threaten bean production and the food security of millions of people who depend on these protein‐rich legumes. Heat stress during the reproductive stages induces pollen sterility, flower abscission, and disruptions in source–sink relationships, resulting in yield losses of 30%–40% or more when critical ...

A 3D Model of Ryegrass Shoot Architecture, Sward Light Interception and Photosynthesis
Increasing the photosynthetic capacity of perennial ryegrass (Lolium perenne L.) is required to improve the productivity of pastoral farming in temperate regions. A three‐dimensional (3D) model was constructed of the shoot growth of ryegrass based on plant morphological traits such as tiller angle, leaf angle, leaf width, number of tillers per plant ...

Operators are exposed to concentrated formulation during mixing of pesticide into the nurse tank and to an in‐use dilution during loading the drone; stratification of exposure for mixing and loading would inform the exposure assessment approach by applying the appropriate dermal absorption considerations.

An Active Beam‐Reconfigurable Retrodirective Array
The proposed beam‐reconfigurable retrodirective array not only enables retroreflection toward the signal source but also achieves flexible beam steering via a tunable reflection plate, offering a viable solution for real‐time multipoint communication and multitarget wireless power transfer.
