Tom - interesting that we are seeing pretty striking differences in vegetative accumulation of anthocyanin in OSU Blue/P20. Note the "blue fruit" at the base of this plant and the "normal" foliage pigmentation. I wonder if anthocyanin accumulation in vegetative tissue is both developmentally and environmentally regulated? We are now in a reliably 80-85 degree day, 65-70 degree night cylcle. Are your temperatures cooler than this? Another observation this afternoon is plant to plant variation in the number of fruits per truss, note the L. pimpinellifolium type truss on this OSU Blue plant.
