Popis: Ten-year tests in 8 locations in the Lower Rio Grande Valley showed that grapefruit (Citrus paradisi Macf.) trees on Swingle citrumelo [C. paradisi x Poncirus trifoliata (L.) Raf.] rootstock grew very poorly on heavy clay soil; trees on sour orange (C. aurantium L.) were much less affected. Trees propagated from a single mother tree of an old-line red grapefruit selection on Swingle citrumelo were stunted and had severe bud union crease, whereas trees propagated from a nucellar California Experiment Station (CES) #3 ‘Redblush’ source were large and productive. Old-clone trees on sour orange also were smaller than CES #3 ‘Redblush’ trees, but showed no bud union crease.
