Abstract

In this study, the encapsulation technology based on the calcium alginate coatingwas applied to some Ficus carica L. genotypes. Uninodal microcuttings (3-4 mm long),excised from in vitro proliferating shoots of three Italian cultivars (‘Bifera’, ‘Palazzo’and ‘Catalanisca’), were employed. The influence of three different plant growthregulators (PGRs): 6-benzylaminopurine (BAP), meta-topolin (MT) and zeatine (ZEA),added to the artificial endosperm, were evaluated. Particularly, the viability, regrowthand conversion parameters of the synthetic seeds were registered after 60 days fromthe sowing on a hormone-free medium. Results showed that the cultivars ‘Catalanisca’and ‘Palazzo’ showed the highest viability average rate (90%), followed by ‘Bifera’(80%). Encapsulated microcuttings regrowth percentage was highest for ‘Palazzo’(86.7%), followed by ‘Catalanisca’ (81.7%) and ‘Bifera’ (66.7%), while the conversionrate was comparable for the three cultivars (43.4, 40.0 and 48.3%, respectively). Astrong interaction between cultivars and PGRs was observed. Moreover, regarding theeffect of the PGRs, BAP and MT provided the best results about regrowth andconversion, even if the cultivar ‘Catalanisca’ presented 100% of regrowth with ZEA. Toour knowledge, this is the first time, that encapsulation technology has been appliedto Italian cultivars of Ficus carica.
