Correlation analysis showed, neither unit leaf area fresh weight ( ULW) nor unit leaf area dry weight ( SLW) was correlative with content ⅰ, but both of them were negative correlation to varying degrees with content ⅱ or ⅲ.

In case of the ULW scale the control action of these forcings can not be ignored and, consequently, the dynamic characteristics of the ULW differ significantly from those of long waves.
