“…Height to diameter ratio was not significantly correlated with five leaf features except for its genetic correlation with length to width ratio (-0.238). Leaf has prime effects on light interception, carbon assimilation and consequently on biomass accumulation (Harrington et al 1997). Leaf features, such as single leaf area, leaf increment rate and petiole length have already been considered reliable productivity determinants (Harrington et al 1997, Monclus et al 2005, Marron & Ceulemans 2006.…”

Leaf features, such as single leaf area, leaf increment rate and petiole length have already been considered reliable productivity determinants (Harrington et al 1997, Monclus et al 2005, Marron & Ceulemans 2006. The close link of leaf features to growth traits in this study ( Table 2) might imply that the leaf features are potential determinants of camphor tree in terms of growth.…”

“…Leaf area has already been considered one of most reliable productivity determinants of poplar hybrids (Harrington et al 1997). It is comparatively easy and cheap to score and its relationships with growth traits of poplar are valid irrespective of growing conditions, which has made it a robust and useful early indicator of tree vigour (Marron et al 2007).…”

“…However, due to the extreme complexity in genetic basis of growth traits, screening for improved genotypes is timeconsuming, costly and laborious (Marron et al 2007). Many scientists have proposed new approaches to achieve this goal by indirectly selecting morphophysiological traits that are cheap and easy to measure (Harrington et al 1997, Marron & Ceulemans 2006, Marron et al 2007). However, the successful application of this strategy requires that the morphophysiological traits are genetically correlated with biomass production and/or growth rates, and that both types of traits are moderately or highly inheritable (Tuberosa et al 2002).…”

To get better understanding of genotypic variations of camphor tree (Cinnamomum camphora), a total of 179 open-pollinated families of seedlings from six provinces of south China were evaluated using leaf and growth characteristics. Families differed significantly in leaf features (leaf area, leaf margin circumference, leaf maximum length, leaf maximum width and leaf length to width ratio), and in growth traits (seedling height, seedling basal diameter and seedling height to basal diameter ratio). High heritability values were found for entire eight traits, ranging from 0.623 to 0.974. Genetic and phenotypic correlation analysis revealed significant and positive associations between leaf features, growth traits as well as both types of traits. Principle component analyses showed considerable diversity in the studied families and 90.65% of total variations were explained by the first three components. Cluster analysis classified these progenies into 16 clusters and each was distinguished by specific characteristics in terms of leaf and growth traits. Linear regression analysis established equations with significant coefficients and correlations for the linking of leaf area to both height and basal diameter. These data could be considered as valuable genetic resources for selecting breeding programmes in future.

“…Although this reduces water loss, the reduction of leaf area also reduces total carbon assimilation and then growth. There are several studies that indicate a strong correlation P between stem volume (or aboveground biomass) and total leaf area in hybrid poplars and their parents (Roden et al 1990, Ridge et al 1986, Harrington et al 1997. Hanington et al (1997) suggested that leaf size characteristics were correlated with biomass/growth.…”
