文摘

N dilution causes down-regulation of net photosynthetic rate under elevated [CO2]. Rubisco carboxylation rate is increased when PRD is applied under elevated [CO2]. Elevated [CO2] induces drought tolerance in grapevines. Leaf respiration rates can either increase or decrease, depending on drought level. Elevated [CO2] improves leaf carbon balance in grapevines.
