AbstractThe relationships among crown characteristics, crown fractal dimensions
   and water consumption were studied in seven 5-year-old poplar clones
   that were selected from the nursery garden of the Gaomi Forestry Bureau
   in China. The closest positive correlation was between single tree leaf
   area (TLA) and water consumption followed by the tree crown area (TCA).
   The leaf area index (LAI) and crown layer density (CLD) were positively
   correlated with water consumption but were not significantly correlated.
   There was a negative correlation between the crown shape ratio (CSR) of
   the L35, NL895 and I-107 poplars and water consumption. The CSR of the
   other clones was positively correlated with water consumption. But
   neither the positive nor negative correlations of CSR with water
   consumptions were significant. The crown characteristics of the fractal
   dimension had a similar variation trend. The fractal dimension had a
   significant positive correlation with TLA, LAI and CLD but no
   significant correlation with CSR and TCA. The fractal dimension of TCA
   (FDa) and the fractal dimension of crown volume (FDv) had a significant
   positive correlation with water consumption, and FDa was more closely
   correlated with water consumption than FDv. More fractal dimension
   resulted in more water consumption. Correlation analysis indicated that
   the presence of more foliage distributed in the crown surface or the
   more evenly distributed foliage in the inner crown resulted in more
   water consumption with the same leaf area.
