Blind nodes in peach, the condition in which a node has no obvious vegetative or reproductive buds, is a problem in peach production in low and medium chill regions. Observations were made at 3 locations in Texas on peach cultivars which range in chilling requirement from 150 to 850 chill units. Four types of growing shoots (terminal or lateral shoot and east or west side) from peripheral canopy about 150-200 cm were sampled twice a month to determine the phonological development. Blind bud development was most frequent during the period of highest daily temperature and did not correspond with the position of the sample on a tree. High chilling cultivars showed greater susceptibility to the symptoms than low chilling cultivars. The anatomical differences between normal and blind nodes are described.
