Abstract:
The effect of long--term N--supply on growth, scab resistance and phenolic compounds in the leaves of two apple cultivars was studied. The different pools of phenylpropanoids (hydroxycinnamic acids, dihydrochalcones) and flavonoids (flavonols, catechins, procyanidins) were quanitfied by HPLC from non--infected and inoculated leaves representing different ontogenetic stages. Scab incidence was also evaluated. Strictly following the carbon--nutrient--balance hypothesis, apple trees responded to hi...     »
