USA, Louisiana - July 13th, 2007 (Joe Omielan) - Project Update

The season has gone well, so far, at Baton Rouge, except for too much rain. The last defoliations will be done in about a week. Dr. Jim Board sent in this series of photos from the DP4331 (MG IV) plots showing the differences in light interception created by the treatments.

Control: Canopy absorbs most of the light.
