AbstractThe stage of ovule development at anthesis and its relationship with fruit set was studied in several apricot cultivars growing in Mediterranean climatic conditions. Although generally the ovule was immature at anthesis, a great variability was found in the stage of development of the ovules from different cultivars. Considering functional ovules to be those with an embryo sac with at least four nuclei at anthesis, the earliest flowering varieties frequently showed more than 50% of functional ovules. Though these results could suggest that there is an influence of the chilling requirement on the percentage of functional ovules at anthesis, data recorded from two cultivars, 'Goldrich' and 'Colorao', with high chilling requirements, contrast with this suggestion. These results indicate that in apricot flowers the development of the embryo sac at anthesis is genotype dependent. The fact that a high frequency of functional ovules at anthesis was found, in cultivars with more than 50% of fruit set, suggests that, to be fertilised, a certain level of development of the apricot ovules at this time is necessary.
