TY - JOUR T1 - Growth Habits of Five Cultivars of <em>Pyrus Calleryana</em> JF - Arboriculture &amp; Urban Forestry (AUF) SP - 160 LP - 163 DO - 10.48044/jauf.1983.039 VL - 9 IS - 6 AU - Heidi Haserodt AU - T. Davis Sydnor Y1 - 1983/06/01 UR - http://auf.isa-arbor.com/content/9/6/160.abstract N2 - Callery pears are upright trees with 3 bad crotch angles and 36 branches in the first 5 feet of the crown. High branch density and narrow crotch angels make this plant very prone to storm damage. The cultivar ‘Aristocrat’ has fewer crotches and a lower branch density, which suggests that this plant may have fewer problems as the plant matures in the landscape. Graphic representations for 5 cultivars are presented and are drawn to scale to allow direct comparison between cultivars for height, width, and habit. ER -
