Red, I seem to remember Carolyn Male making a statement that a certain number of leaves are required on a plant to provide nutrients from photosynthesis for each developing tomato (paraphrased). I don't remember all of the details, but it seems possible that limiting the stems may limit the required number of leaves. It could also be possible that different varieties with different leaf types, sizes, and shapes could influence each varieties ability to perform well as single stem or multi stem plants. If that is true, I wonder how the "stick" tomato plant is able to fully develop fruit with all of its leaves bunched tightly against the main stem. Ted
