Influence of rootstock on fruit entity, quality and antioxidant properties of fresh apricots (cv. ‘Pisana’)
No full textThe influence of two commercial Prunus rootstocks (‘Myrabolan 29/C’ and apricot ‘Seedling’) on fruit
entity and quality of ‘Pisana’ apricot cultivar (Prunus armeniaca L.) was evaluated over two consecutive
crop seasons. The effect of rootstock on the total antioxidant capacity, total phenols and physicalchemical
traits of fresh apricots was studied at the ready-to-eat stage and after 14 days at 4 °C cold
storage. The rootstocks had no significant influence on the flowering and fruiting entity but affected
some fruit quality traits. The ‘Myrabolan 29/C’ appeared to induce the highest fruit weight, total
antioxidant capacity and total phenols. The results showed an important role of the climatic conditions
in determining the fruit antioxidant content. A drought ripening period improved the antioxidant
potential of fruit independently of the rootstock. After cold storage, apricot fruits maintained good
levels of antioxidants

Pisa University's Contribution to the National Apricot Breeding Program: Three New Apricot Cultivars for Tuscan Fruit Growers
No full textAfter five years of selection, the Dipartimento di Coltivazione e Difesa delle Specie Legnose (DCDSL) at Pisa University can offer three new apricot cultivars resulting from the Italian apricot breeding programme, financed by the Ministry of Agriculture (MiPAF). The first cultivar, 'Angela', is an early-maturing cultivar which ripens around 3 weeks before 'Canino' and a few days before 'Priana'. The second one, 'Gheriana', ripens 10 days before 'Canino', at the same time as 'Orange Red'. It is a cross between 'Portici' x 'Harcot', with the best traits of both parents. The third one, 'Silvana', is a late-maturing cultivar that ripens 25 days after 'Canino' and 10 days later than 'Fantasme'. It is a cross between 'Bergeron' x 'Canino Tardivo', and is heavy-cropping
Parents for spring frost tolerance in apricot
No full textApricot (Prunus armeniaca L.) is particularly sensitive to spring frosts, which can cause irreversible damage to the flower buds or to the just-set fruits. In order to evaluate if the differences in frost tolerance, observed under field conditions, could be confirmed, cold-stress tests under artificial sub-zero temperatures were conducted, eliminating the multiple variables of the field. The results showed a different degree of cold tolerance according to the genotype and the phenological stage. After the break of endo-dormancy and at the pre-flowering stage, when flower buds are generally more susceptible, some genotypes ('Haggith', 11/48/2, 7C/20/3, 2/29/11) were hardy, not only at -4 degrees C, but also at -8 degrees C. The frost-hardy genotypes, identified in natural conditions by satisfactory yields, showed an elevated tolerance to freeze damage after artificial cold treatments too
