Line Plot from Scientific Research

Growth measured as area of fronds (or aerial tissues for Pistia), derived from daily imaging from beneath, and plotted as a percentage increase relative to the initial (day 1) area value. Species are indicated on the graphs. n = 10 flasks, each initially seeded with 3 colonies for duckweed and 1 plant for Pistia. Asterisks show statistically significant (p <= 0.05) differences as assessed by two-way repeated-measures ANOVA followed by Sidak’s multiple comparisons. Error bars = 95% CI. Lines show the best fit of an exponential (Malthusian) growth curve.
