Moutinho-Pereira et al. (2009)

Photosynthesis (in 2004) of plants grown "using standard cultural decisions," but without irrigation, from 2004-2006 in a vineyard in northern Portugal, where they were enclosed in open-top chambers with CO2 being supplied to half of them during daylight hours between the times of budbreak and harvest, with measurements being made during the ripening stage
