USA, Lexington Kentucky - March 23, 2009 (Joe Omielan) - Project Update
For the third year we are studying the effects of SBR on soybeans in controlled environment chambers during the winter. For this experiment we built a chamber where you can put in an entire trifoliolate leaf and measure leaf respiration using the LI-6400.
The photo above shows a leaf being sealed in the leaf chamber.
Respiration measurements are taken in a darkened growth chamber (see photo above).
This is an example of tan sporulating lesions on a susceptible plant.
This is an example of red brown non-sporulating lesions on a resistant plant.
