英语. The investigation shows the effect of different nitrogen levels on the differentiation of flower buds in the variety Ersinger. The fertilization was performed with various amounts of nitrogen (50, 80 or 120 kg N/hectare) at the beginning of March, and in June there was a post-fertilization (+0, +20 or +30 kg N/hectare respectively). It was found that by increasing the nitrogen supply (80 + 20 kg N/hectare and 120 + 30 kg N/hectare) flower-bud differentiation was accelerated and thus flower quality improved. Furthermore it was shown that a positive correlation exists between the nitrogen level and the increase in the number of buds containing two flowers

Oggetto degli studi e' stata l'influenza di crescenti dosi di azoto (0, 50, (80 + 20) e (120 + 30) kg N/ha) sulla differenziazione delle gemme fiorali. La differenziazione delle gemme a fiore si avvantaggia, nella Ensinger, somministrando dosi di fertilizzante, come 80 + 20 kg N/ha e 120 + 30 kg N/ha. La loro qualita' viene migliorata (precoce differenziazione degli stami) ed il numero delle gemme bifiorali aumenta in relazione alla quantita' di azoto somministrato
