Photosynthetic response of umbu trees to vapor pressure deficit

Pesquisa Agropecuária Brasileira, 2022
The objective of this work was to evaluate the photosynthetic response to vapor pressure deficit (VPD) in umbu (Spondias tuberosa) tree accessions. The experiment was carried out in a completely randomized design in a 5×7×2 factorial arrangement (five ...

Plant responses to rising vapor pressure deficit [PDF]

New Phytologist, 2020
SummaryRecent decades have been characterized by increasing temperatures worldwide, resulting in an exponential climb in vapor pressure deficit (VPD). VPD has been identified as an increasingly important driver of plant functioning in terrestrial biomes and has been established as a major contributor in recent drought‐induced plant mortality ...

Disentangling the effects of vapor pressure deficit on northern terrestrial vegetation productivity. [PDF]

Sci Adv, 2023
The impact of atmospheric vapor pressure deficit (VPD) on plant photosynthesis has long been acknowledged, but large interactions with air temperature (T) and soil moisture (SM) still hinder a complete understanding of the influence of VPD on vegetation production across various climate zones.

The functional dependence of canopy conductance on water vapor pressure deficit revisited

International Journal of Biometeorology, 2018
Current research seeking to relate between ambient water vapor deficit (D) and foliage conductance (gF) derives a canopy conductance (gW) from measured transpiration by inverting the coupled transpiration model to yield gW = m - n ln(D) where m and n are fitting parameters. In contrast, this paper demonstrates that the relation between coupled gW and D
