Abstract
Fruits on uniform peach shoots selected from the periphery of trees were thinned to leave only those nodes of the terminal, intermediate, or basal regions of the shoot, or at 6” spacings along the shoot. The control consisted of unthinned shoots. During one year of the study the date of 90% bloom of buds at the various node positions and size of the subsequent fruit was determined. During the second year fruit volume and mean ovule length were determined for each thinning treatment.
Flower buds from the terminal nodes were the first to bloom the resulting fruit were the largest at harvest. Conversely, buds at the basal nodes were the last to bloom and produced the smallest fruit. In treatments that included fruit from all node positions, the mean fruit volume was smaller than for shoots having fruit only at the terminal nodes. Mean ovule length was also influenced by node position.
