Journal ArticleDOI
Use of infrared thermography for monitoring stomatal closure in the field: application to grapevine
Hamlyn G. Jones,Manfred Stoll,Tiago P. Santos,Claudia de Sousa,Maria Manuela Chaves,Olga M. Grant +5 more
TL;DR: This paper reviews and discusses strategies for the use of thermal imaging for studies of stomatal conductance in the field and compares techniques for image collection and analysis and evidence is presented that the temperature of reference surfaces exposed within the canopy can be affected by the canopy water status.
Journal ArticleDOI
Deficit irrigation in grapevine improves water‐use efficiency while controlling vigour and production quality
Maria Manuela Chaves,Tiago P. Santos,C.R. Souza,María Fernanda Ortuño,M. L. Rodrigues,Carlos M. Lopes,João Maroco,João Pereira +7 more
TL;DR: It is shown that the amount of water applied by 50% in relation to full crop's evapotranspiration (ETc) (full irrigated (FI) vines) with no negative effects on production and even get some gains of quality (in the case of PRD), and growth inhibition in PRD was not a result of a hydraulic control.
Journal ArticleDOI
Partial rootzone drying: effects on growth and fruit quality of field-grown grapevines (Vitis vinifera)
Tiago P. Santos,Carlos M. Lopes,M. Lucília Rodrigues,Cláudia R. de Souza,João Maroco,João Pereira,Jorge Manuel Ricardo da Silva,Maria Manuela Chaves +7 more
TL;DR: Water use efficiency was increased by about 80% in PRD and DI when compared with FI, as a result of almost similar yields in the three treatments, while yield gains of irrigated plants in relation to NI were modest.
Journal ArticleDOI
Partial rootzone drying: regulation of stomatal aperture and carbon assimilation in field-grown grapevines (Vitis vinifera cv. Moscatel)
Cláudia R. de Souza,João Maroco,Tiago P. Santos,M. Lucília Rodrigues,Carlos M. Lopes,João Pereira,Maria Manuela Chaves +6 more
TL;DR: It is shown that PRD irrigation was able to maintain a vine water status closed to FI, but with double water use efficiency, which was due to a reduction of stomatal conductance with no significant decrease in carbon assimilation.
Journal ArticleDOI
Effects of deficit irrigation strategies on cluster microclimate for improving fruit composition of Moscatel field-grown grapevines
Tiago P. Santos,Carlos M. Lopes,M. Lucília Rodrigues,Cláudia R. de Souza,Jorge M. Ricardo-da-Silva,João Maroco,João Pereira,Maria Manuela Chaves +7 more
TL;DR: In this article, the effect of partial root-zone drying (PRD) irrigation on vine water relations, vegetative growth, plant microclimate, berry composition and yield components, compared to conventional deficit irrigation (DI, 50% ETc), full irrigation (FI, 100% of ETc) and non-irrigated vines (NI).
