摘要

The anatomy of 9 cultivars of spur-type apples and 2 of standard type apples were studied using Jeffrey's separation method and ultrathin sectioning for electron microscopy. Vessel members of the secondary xylem of the spur-type and standard applesare all pitted vessels. The length and diameter of the vessel members of the spur-type apple are markedly less than those of the standard apple. Secondary xylem have more sieve elements with varied secondary thickenings.
