FRUITSET ACCORDING TO THE NUMBER OF FLOWERS ASSOCIATED AT THE SAME AXILLARY BUD IN PEACH. |

| Abstract:
A morphological description one-year-old shoots of peach, reveals various combinations of flower and vegetative buds, apparently located at the same node. The purpose of this study is to investigate fruitset in relation to the number of flowers associated at the same axillary bud. We can consider the capacity of one flower to set fruit as the outcome of a Bernouilli experiment (1, p). In the case of n independent associated flowers, the distribution of the number of fruits could be fitted to a binomial distribution B(n, p). From a comparison of the expected and observed data, we can analyse the dependency of flowers for their fruitset. Fruitset distributions are analysed for different peach cultivars. Our data suggest genotypic influences on the dependency of flowers within a association. This study is the preliminary step to investigate fruitset along the shoot, since it deals at the level of the buds associations. It can be carried out by the investigation of the relationships between adjacent associations along the shoot, according their fruitset. | |
