Abstract
SummaryA 14-week study was conducted to investigate differences in growth characteristics between cvs Lovell and Nemaguard peach rootstocks. Nemaguard exhibited a higher absolute growth rate, and had significantly greater values for leaf weight ratio and leaf-root dry weight ratio as compared to Lovell. Significant differences were detected between the two cultivars for root-shoot ratio and fresh weight-dry weight ratio. Nemaguard had a significantly greater root-shoot ratio early in development but exhibited a lower ratio for the final four harvest dates. The fresh weight-dry weight ratio showed a similar pattern. No significant differences in relative growth rate, unit-leaf rate or leaf area ratio were detected.
