Encapsulation of black mulberry microcuttings: studies on capsules and synthetic seeds
2017
The encapsulation technology for plant tissue culture can be an efficient tool to optimize the plant management systems and to preserve valuable plant germplasm. In this paper, two experiments were carried out to evaluate the encapsulation efficiency in mulberry (Morus nigra L.). In the first experiment, gel capsules were stored at 4°C for different times (0, 30, 90, 180 and 360 days). The highest percentage of shoot viability (82.5%) and regrowth (72.5%) was scored after 180 days of storage, with an average development of 2.5 shoots/capsule. The second experiment was aimed to point out an efficient protocol to turn the capsules of black mulberry in synthetic seeds ready to develop into who…
In vitro response of two Sicilian genotypes of Morus (L.) through axillary bud culture.
2007
A protocol for the in vitro establishment of two Sicilian genotypes of mulberry has been set up. Multiple shoots were initiated and plantlets were produced from buds collected from mature trees of Morus alba L. and Morus nigra L., grown in the field. The influence of two explanting times (September and December) of buds on the in vitro response has been observed. The percentage of sprouting after four weeks of culture was greatly higher with material explanted from the field in September compared with the one collected in December. Morus nigra L. produced more vigorous shoots than Morus alba L.. After the second subculture the number of shoots produced decreased, in both genotypes. No diffe…
Gelso in Sicilia: qualità, caratterizzazione e comportamento dei frutti in post-raccolta
2019
Il gelso è una pianta arborea originaria dell'Asia e della Persia, introdotta in Italia dai Romani per le sue proprietà medicinali, oltre che per fini alimentari. Si distinguono due specie principali, comunemente denominati: gelso bianco e nero. I frutti, tipiche more di colore bianco violaceo o nero, sono molto apprezzati dall'uomo sin dall'antichità, sebbene vengano spesso collocati tra i frutti minori per la loro scarsa diffusione commerciale. Oggi, l'elevato interesse per le proprietà nutraceutichedi tali frutti spinge gli agricoltori ad una rivalutazione della gelsicoltura. Punto dolente della commercializzazione del gelso è la gestione post-raccolta a causa della brevissima shelf-life…
