Maturation and related aspects in clonal forestry—Part I: concepts, regulation and consequences of phase change

open access: yesNew Forests, 2014
Progression from the juvenile to mature phase in woody plants is accompanied by changes in characteristics as diverse as adventitious rooting capacity, leaf morphology, canopy architecture, wood anatomy and reproductive development. Many concepts of phase change, the intensity and duration of changes that occur during the phase transition, and the ...
