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 ...

Exploring agronomic and physiological traits associated with the differences in productivity between triticale and bread wheat in mediterranean environments
Méndez-Espinoza, Ana María; Romero-Bravo, Sebastián; Estrada, Félix; Garriga, Miguel; Lobos, Gustavo A.; Castillo, Dalma; Matus, Iván A.; Aranjuelo, Iker; Del Pozo, Alejandro (2019)In Mediterranean climates soil water deficit occurs mainly during the spring and summer, having a great impact on cereal productivity. While previous studies have indicated that the grain yield (GY) of triticale is usually ...

Genotypic variations in leaf and whole-plant water use efficiencies are closely related in bread wheat genotypes under well-watered and water-limited conditions during grain filling
Del Pozo, Alejandro; Méndez-Espinoza, Ana María; Romero-Bravo, Sebastián; Garriga, Miguel; Estrada, Félix; Alcaíno, Marta; Camargo-Rodriguez, Anyela V.; Corke, Fiona M.; Doonan, John H.; Lobos, Gustavo A. (2020)Wheat plants growing under Mediterranean rain-fed conditions are exposed to water deficit, particularly during the grain filling period, and this can lead to a strong reduction in grain yield (GY). This study examines the ...

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 ...
