Comparison between the observed (points) and predicted fresh weights by using dry weights (the straight line) of I. barbatus. 30 leaves were randomly picked from these plants in the Nanjing Forestry University campus on 11 August, 2015. We measured their fresh weights as soon as we picked them from the plants (17:00 or so). Then these leaves were transferred to the oven at 60°C for 48 h. We measured their corresponding dry weights at 18:00 on 13 August, 2015. Then a linear regression was conducted between fresh weight (WF) and dry weight (WD). The estimate of slope is 2.0830 ± 0.0178, and R2 = 0.9979. That is, there is a strong proportional relationship between fresh and dry weights.
