Journal ArticleDOI
Effects of drought on photosynthesis in grapevines under field conditions: an evaluation of stomatal and mesophyll limitations.
TL;DR: The apparent carboxylation efficiency and the compensation point for CO2 remained unchanged under severe drought when analysed on a Cc, rather than a Ci, basis, suggesting that previously reported metabolic impairment was probably due to decreased gmes.
Journal ArticleDOI
UAVs challenge to assess water stress for sustainable agriculture
Jorge Gago,Cyril Douthe,Rafael E. Coopman,Pedro P. Gallego,Miquel Ribas-Carbo,Jaume Flexas,José Mariano Escalona,Hipólito Medrano +7 more
TL;DR: In this paper, the authors reviewed the application of different types of UAVs using different remote sensors and compared their performance with ground-truth plant data, such as NDVI, TCARI/OSAVI and PRInorm.
Journal ArticleDOI
Steady-state chlorophyll fluorescence (Fs) measurements as a tool to follow variations of net CO2 assimilation and stomatal conductance during water-stress in C3 plants
Jaume Flexas,José Mariano Escalona,Sebastian Evain,Javier Gulías,Ismael Moya,C. B. Osmond,Hipólito Medrano +6 more
TL;DR: The ratio Fs/Fo, measured with a portable instrument (PAM-2000 or with a remote sensing FIPAM system, provides a good method for the early detection of water stress, and may become a useful guide to irrigation requirements.
Journal ArticleDOI
Understanding down-regulation of photosynthesis under water stress: future prospects and searching for physiological tools for irrigation management
Jaume Flexas,Josefina Bota,Josep Cifre,José Mariano Escalona,Jeroni Galmés,Javier Gulías,Elkadri Lefi,Sara Florinda Martínez‐Cañellas,María Teresa Moreno,Miquel Ribas-Carbo,Diego Riera,Bartolomé Sampol,Hipólito Medrano +12 more
TL;DR: An analysis of published data reveals that a key regulatory role for Rubisco in photosynthesis is improbable under water stress conditions, and the little data available for other Calvin cycle enzymes suggest the possibility of a key Regulatory role for some enzymes involved in the regeneration of RuBP.
Journal ArticleDOI
A ten-year study on the physiology of two Spanish grapevine cultivars under field conditions: effects of water availability from leaf photosynthesis to grape yield and quality
TL;DR: There is a close link between water availability and grape yield, mostly through water stress effects on photosynthesis, while drought effects on grape quality are linked to water availability but not to photosynthesis or yield.
