Abstract :Sclerophylly and foliar nutrient status and interactions between these factors in ash insert ignore into journalissuearticles values( Fraxinus angustifolia Vahl. subsp. oxycarpa insert ignore into journalissuearticles values(Bieb. ex Willd.); Franco & Rocha Afonso); and laurel insert ignore into journalissuearticles values( Laurus nobilis L.); species were examined. In addition, correlations between sclerophyll index and leaf and soil parameters were investigated. It was found that there were statistically significant differences between the mid-growing season and the end of the growing season with respect to leaf N % concentration, N/Ca and N/Mg ratios in ash, and with respect to leaf N % concentration and soil K % concentration in laurel. The sclerophyll index was negatively correlated with leaf P % concentration in both species. Some important correlations were also found between leaf and soil nutrient concentrations.
