Response of rice (Oryza sativa) to change in vapour pressure deficit
Changes in climatic conditions are expected to directly affect agricultural production systems including rice farming. However, maintaining and increasing productivity in the face of climate change will require improved understanding of the effects of climatic factors on rice physiological traits. Increasing temperatures will lead to changes in atmospheric vapor pressure deficit (VPD). VPD can affect rice growth by affecting the water status of the plants, the thermal conditions of leaves or the canopy thereby regulating plant functions. This experiment aimed to determine the effects of VPD on growth and physiological responses of a range of rice genotypes in order to better understand these effects and their implications for adaptation to climate change.
