| Abstract:
Within the framework of the studies that have been undertaken to model apricot trees, an understanding was needed of the major phenomena that occur during the transformation of a flower to a fruit. This includes quantifying pollen quality, flower anomalies, fertilization rate, ovule viability and the rate of flower and fruit drop. This report discusses the research that has been conducted in France since 1990 on the major cultivar 'Rouge de Roussillon'. It appeared that flower and fruit drop was a continuous process, but the major drop occurred from 12 to 35 days after blossoming. The drops after this initial period are drastically reduced, and not associated with a lack of pollination and fertilization. | |
