Seasonal variation of nutrient elements in peach fruits (cv. May Crest) and its correlation with development of Brown rot (Monilinia laxa)

In this study, the seasonal variation of nutrient elements in peach fruits (cv. May Crest) was examined. Generally, peach nutrients content was highest in the first stages of fruit formation (April) and gradually reduced by developing of fruit. The susceptibility of peaches at different growth stages to Monilinia laxa was also investigated. Fruits were susceptible to M. laxa only at harvesting time, namely later from the date in which fruit nutrients content was the lowest showing no correlation with seasonal variation of nutrient elements in peach flesh.
