Figure 2. Weights (% of their original weight) of intact and demucilaged A. sphaerocephala achenes during dew treatment (from 20:00 pm 28 August to 20:00 pm 1 September, 2009).

Achenes were weighed at 1 h intervals, and achene weights were expressed as % of their original weight. All data were the mean of three replicates. The arrows indicate sampling times of achenes (at 20:00 pm each day).
