Estimating carbon isotope discrimination and grain yield of bread wheat grown under water-limited and full irrigation conditions by hyperspectral canopy reflectance and multilinear regression analysis
Garriga, Miguel; Romero-Bravo, Sebastián; Estrada, Félix; Méndez-Espinoza, Ana María; González-Martínez, Luis; Matus, Iván A.; Castillo, Dalma; Lobos, Gustavo A.; Del Pozo, Alejandro (2021)Water deficit is the most limiting factor for wheat production, so wheat-breeding programmes are currently focused on developing high-performance genotypes under such conditions. Carbon isotope discrimination (∆13C) in ...

Spectral reflectance modeling by wavelength selection: Studying the scope for blueberry physiological breeding under contrasting water supply and heat conditions
Lobos, Gustavo A.; Escobar-Opazo, Alejandro; Estrada, Félix; Romero-Bravo, Sebastián; Garriga, Miguel; Del Pozo, Alejandro; Poblete-Echeverría, Carlos ; González-Talice, Jaime; González-Martínez, Luis; Caligari, Peter D. S. (2019)To overcome the environmental changes occurring now and predicted for the future, it is essential that fruit breeders develop cultivars with better physiological performance. During the last few decades, high-throughput ...

Thermal imaging reliability for estimating grain yield and carbon isotope discrimination in wheat genotypes: Importance of the environmental conditions
Romero-Bravo, Sebastián; Méndez-Espinoza, Ana María; Garriga, Miguel; Estrada, Félix; Escobar-Opazo, Alejandro; González-Martínez, Luis; Poblete-Echeverría, Carlos ; Sepúlveda, Daniel; Matus, Iván A.; Castillo, Dalma; Del Pozo, Alejandro; Lobos, Gustavo A. (2019)Canopy temperature (Tc) by thermal imaging is a useful tool to study plant water status and estimate other crop traits. This work seeks to estimate grain yield (GY) and carbon discrimination (Δ13C) from stress degree day ...
