This paper deals with the study of seasonal variations on leaf nutrient concentrations in Ginkgo biloba L. The result has indicated that concentrations of N,P,K,Ca,Mg,B,Fe,Zn,Mn,Cu in the leaves of male and female trees varied throughout the growing season. Leaf nutrient concentrations of N,P,K,B,Fe,Zn differ significantly between male and female trees in three years ( P ≤0.05),but the concentrations of Ca,Mg,Mn,Cu do not differ significant...
