Importance of organ age in driving intraspecific trait variation and coordination for three evergreen coniferous species

Plant functional traits play an important role in plant growth and community composition in forest ecosystem. However, how the intraspecific trait variations for both leaf and branch were driven by organ age is less clear. We chose three evergreen coniferous species in the mixed broadleaved-Korean p...
