Abstract
`Redhaven' peach [Purnus persica (L.) Batsch] trees which were either own-rooted (OR) or June-budded (JB) the previous year were headed back at planting to either (1) 70-85 cm above the soil surface (CH, conventional heading) or (2) the first bud 20-30 cm above the soil surface (LH, low heading). Propagation method had no effect on fruit yield in 1988 or trunk cross-sectional area; however, total yield in 1987, and the cululative yield for 1987 and 1988 were significantly greater for JB trees than for OR trees. LH reduced survival of OR trees, but not the JB ones. Cold injury was greater for the OR trees than for the JB ones. Neither propagation nor heading height influenced bloom density, fruit set in 1987, or fruit size in 1988. However, OR trees which were conventionally headed produced larger fruits in 1987 than did JB trees the same year.
