Duckweed competition

[sjohnson at FRANK.MTSU.EDU]

greg.

i'd be interested in knowing more about the experiment you're 
planning. why duckweed? what experimental design? will it take a 
lot of space? i'm just finishing my 1st semester teaching a intro 
botany course & feel the labs could be better.
