A general formula for determining leaf area of a kind of broadleaved tree


, : A general formula for determining leaf area of a kind of broadleaved tree. Journal of Ecology Beijing 9(1): 60-61

An empirically-based formula is presented for determining the leaf area of certain broadleaves quickly and accurately. The equation is based on a spindle-shaped form symmetrical about the long and short axes.

We used green fluorescent fusion protein assays to demonstrate that the Arabidopsis MEP path...
