If you want a turnkey system specifically set up for root length & area
measurement, check into Skye Instruments' Root Analysis System. They're in
the UK; the most recent address I have for the US distributer is
PO Box 278
Perasie, PA 18944
It's very pricey though. At one time, I believe Decagon Devices also
marketed one (PO Box 835, Pullman, WA; 509: 332-2756).
We have made similar measurements on lichens, and have found NIH's
freeware program, Image, to be adequate. There is much more to fuss with,
though, on a program not dedicated to such measurements.
Good luck -
