Table III
Calibration equations for each leaf stage when the data from the four Quercus species were pooled. The equations convert the CCI value into the estimated total chlorophyll content per unit area (mg cm−2).
Leaf stage | n | Equation | P | r 2 |
---|---|---|---|---|
Young leaves | 120 | Log(Chl) = –4.732 + 0.518 Log(CCI) | < 0.0001 | 0.77 |
Fully expanded | 120 | Log(Chl) = –5.799 + 0.834 Log(CCI) | < 0.0001 | 0.73 |

Mature leaves | 120 | Log(Chl) = –4.792 + 0.553 Log(CCI) | < 0.0001 | 0.70 |
