Results of the bioassays employing foliar applications of the 8 samples at 2 carbon rates. The DOC rates used were 0.01 and 0.1 mg/L C, and the average a) shoot and root lengths (cm) and b) dry shoot and root masses (mg) for all seedlings are given. Shoot measurements are given in green, while root measurements are given in blue. Error bars are the standard deviations of the 10 individual measurements for each treatment. Circles around data points indicate that the data point is statistically better (p ≤ 0.05) than the control. The dotted lines across the plot indicate the control average for each type of measurement. Actual measurements and p values are given in Table 5.
