Journal ArticleDOI
The Photochemical Reflectance Index (PRI) as a water-stress index
TL;DR: In this paper, the authors measured the reflectance in two narrow wavelength bands centred around 531 and 570 nm during withering of two contrasting functional and structural plant types: Chenopodium quinoa (Willd) and Arbutus unedo (L).
Journal ArticleDOI
Downscaling MODIS-derived maps using GIS and boosted regression trees: The case of frost occurrence over the arid Andean highlands of Bolivia
TL;DR: In this article, the authors explored how regional and landscape-scale features influence night frost occurrence in the southern altiplano of Bolivia and compared multiple regression (MR) and boosted regression trees (BRT).
Journal ArticleDOI
Response of some Andean cultivars of quinoa (Chenopodium quinoa Willd.) to temperature: Effects on germination, phenology, growth and freezing
TL;DR: Low leaf water status delayed the freezing process, while leaf vesicles did not seem to play any protective or detrimental role towards leaf freezing, and thermal sensitivity in germination was not related to the geographic origin of the cultivars.
Journal ArticleDOI
Influence of Water Stress on Grapevines Growing in the Field: From Leaf to Whole-Plant Response
Thierry Winkel,Serge Rambal +1 more
TL;DR: The utility of integrating data on stomatal conductance, leaf water potential and whole-plant hydraulic conductance to interpret whole plant adaptation to water stress is demonstrated, and two mechanisms by which genotypes differentially acclimate to water Stress are elucidated.
Journal ArticleDOI
Effect of the timing of water deficit on growth, phenology and yield of pearl millet (Pennisetum glaucum (L.) R. Br.) grown in Sahelian conditions
TL;DR: In this article, the authors assessed the impact of water deficits at three development stages: prior to flowering (S30), at the beginning of flowering and at the end of flowering in pearl millet grown in experimental conditions similar to Sahelian farming conditions.
