Dear All, Sept 13, 2007
I recently washed some Rosa rugosa seeds free of ripe pulp and after
brief drying put them in a dish of water to remove remaining traces of pulp.
They floated but in a non-uniform distribution, i.e. in clusters.
This appears to be a surface tension.effect. When one seed is pulled
away from a cluster 5 mm or so ii is slowly and then more rapidly drawn
to the nearest seed.
