Analysis of Trace Element Concentrations from Eucalypt Leaves Showing Slow-growing Symptom
Symptom so called "slow - growing" had been observed on eucalypti plantations in Guangdong in the past few years. In order to test whether the symptom was caused due to the deficiency of trace elements, concentrations of B,Cu,Zn,Fe,Mn elements were measured from both healthy and diseased mature leaves of Eucalyptus urophyila (U6) .The results showed that there were significant differences of concentrations of B, Cu,Zn,Mn between healthy and diseased leaves.The cluster analysis of 10 samples,5 healthy and the other diseased, from one locality further showed the similar trend. The findings suggested that slow - growing symptom of eucalypt plantations in Guangdong could be related to trace element deficiency.
