Other claims from this paper (9)
- Mechanism Leaf water potential apparently primarily controls changes in clear-day photosynthesis, especially the midday decrease.
- Mechanism In noble fir, water potential probably controls photosynthesis mainly through stomatal movement.
- Mechanism In grand fir, mesophyll resistance to CO2 diffusion probably plays a more important role in photosynthesis control.
- Mechanism In Douglas-fir, mesophyll resistance to CO2 diffusion probably plays a more important role in photosynthesis control.
- Mechanism In hemlock, mesophyll resistance to CO2 diffusion probably plays a more important role in photosynthesis control.
- Mechanism In Sitka spruce, mesophyll resistance to CO2 diffusion probably plays a more important role in photosynthesis control.
- Mechanism Stomatal and mesophyll mechanisms probably operate concurrently in all studied conifers.
- Mechanism Daily conifer leaf water potential variations seem primarily driven by the leaf-to-atmosphere vapor pressure gradient.
- Mechanism Carbohydrate variation may also affect leaf water potential through solute concentration.
