Abstract
Nutrient resorption during leaf senescence, specifically nitrogen resorption has been documented to contribute to storage reserves and provide resources to support flowering, and early fruit and vegetative growth in spring.
In this study, we measured the leaf nutrient concentration (N, P, K, Ca, Mg) of nine peach cultivars (three early-season, three mid-season, and three late-season cultivars) throughout the two months before leaf abscission for two years.
Overall, early-season cultivars had higher leaf P and K than mid- or late-season cultivars such as Ca or Mg.
We believe that understanding resorption patterns among different cultivars can provide us with guidance for rational fertilization practices in fruit orchards.
