Seasonal Variations of Leaf Nutrient Concentrations in Ginkgo biloba L.

  • Received Date: 1995-09-13
  • 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 significantly. The big fruit female clone has had the best ability of absobing P,K,B,Zn and the worst of absorbing Ca,but their seasonal variations of the concentration of N, Mg,Fe,Mn,Cu are similar amomg the other female clones.

Abstract: 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 significantly. The big fruit female clone has had the best ability of absobing P,K,B,Zn and the worst of absorbing Ca,but their seasonal variations of the concentration of N, Mg,Fe,Mn,Cu are similar amomg the other female clones.
