| Abstract:
As many as 150 varieties of peaches and nectarines have been studied in Hungary by our team during the period of 1960–1996. The main objective was the assessment of the conditions of fertilisation and fruit set, as for the comparison of natural self-pollination and open pollination. The rate of fruit set from open pollination showed the highest values in peaches amongst all stone fruits. The rates of fruit set through autogamy or open pollination, both varied considerably according to growing site, season and variety. The effect of the growing season, i.e. the weather during the blooming period, prevailed over the varietal tendencies. Fruit set from either self-pollination or open pollination was always inferior in nectarines than in peaches for both fresh market type or processing clingstones. Natural self-pollination produced lower fruit set than artificial self-pollination, moreover, the activity of honeybees increased substantially the rate of fruit set on open standing flowers. | |
