Environmental conditions are expected to vary as a consequence of climate change, particularly considering the notorious rise of atmospheric CO2 levels, the incremental increase of global temperature, and the intensification of drought periods.
The effects of these environmental factors on grapevines (Vitis vinifera L.) have been studied independently, pointing towards changes in must compositio; however, research on their interactions is also important.
The objective of this experiment was to determine the effects of an increment of atmospheric CO2 and temperature, as well as water deficit, on the physiology and berry composition of four different somatic variants of Tempranillo (306, 43, 1084 and VN31). The results show how differences based on environmental growth conditions affected plant phenology, leaf photosynthesis, plant growth, and berry composition.
The paper reproduced in this video-seminar was presented at the International Congress on Grapevine and Wine Sciences - ICGWS (Logroño, Spain, November 7-9, 2018) organized by ICVV.
