Why do trees adjust water relations and hydraulic architecture in response to nutrient availability? [PDF]

open access: yes, 2013
Studies on water relations, hydraulic architecture and effects of nutrients on growth in trees have been studied for many years in relative isolation. Only recently the functional relations of these groups of plant traits have been investigated with a ...
