Abstract

Container size and shape, potting medium, and genotype interacted to influence the growth of black walnut (Juglans nigra L.) seedlings. Larger containers tended to produce larger trees. In tall, narrow, vent-pipe containers, different, proportions of peat and sand in potting media had no effect on total weight; a higher proportion of peat than of very fine sand in the potting media reduced the shoot root ratio. In conventionally shaped pots, seedlings averaged 123 percent heavier when grown in a soil mix containing 75 percent peat and 25 percent sand than when grown in pure sand.
