On stomatal behavior in the Greenland Mountain birch
The study was conducted to determine response of birch stomata to evaporative demand and plant internal water status. The experiment was undertaken in Qinguadalenat a site with microtopographical variation. Comparisons were made between trees from a dry hill and from a moist river bank, respectively...
