Matching plant species such as grapevines to climate is an important consideration in determining crop productivity. Merlot had higher rates of photosynthesis compared with Chardonnay grapevines from 15 to 40oC, even at high CO2. More sugar was accumulated in Merlot berries suggesting Chardonnay grapevines were poorly matched to a hot climate.
