| growth in two common gardens reveals species by environment interaction in carbon isotope discrimination of eucalyptus. | one-year-old sun leaves of 60 species of eucalyptus were collected in august 2005 at an arboretum in south australia with a mean annual rainfall of 427 mm, and 14 of the same species were sampled at an arboretum in western australia with a mean annual rainfall of 216 mm. we determined the genetic and phenotypic variation in carbon isotope composition (delta13c), specific leaf area (sla) and nitrogen content per unit area of the species at each site. there were very significant (p < 0.001) differ ... | 2010 | 20462935 |
