trees double budded in the nursery; and single axis. In-row tree spacings are 3 feet, 4.5
feet, or 6 feet, with 12 feet between the rows.
After two seasons, trees on Pyro-233 had smaller trunks than trees on other root-
stocks. Individual axes of bi-axis trees, where the vigor is spread over the two axes, were
half the size of single axis trees trained to other systems and had more flowers. Einhorn
expects that as the trees grow, those planted with the closest in-row spacing will be more
dwarfed because of inter-tree competition.
