The potential of the Sorb (Sorbus domestica L.) as a minor fruit species in the Mediterranean areas: description and quality traits of underutilized …
2017
Biodiversity linked to fruit cultivation plays a key role in terms of the availability of quality products and nutraceutical compounds for the food industry. Thus underutilized species such as Sorbus domestica L. can be an important resource. The aim of this study was to evaluate 31 local accessions from different growing areas on the Island of Sicily and characterize the fruits according to the biometric-carpological features that constitute their quality in order to understand the potential that this species may have not only regarding the recovery and preservation of genetic resources in the Mediterranean area but also the nutraceutical compounds it offers. The results from this prelimin…
Adventitious shoot regeneration from hypocotyl cultures of service tree(Sorbus domesticaL.)
1992
Effects of growth regulators and N03:NH4 ratio were investigated to determine the mor- phogenic capacity of hypocotyl explants of service tree (Sorbus domestica L.) Organogenic responses were preceded by an initial callus phase and depended mainly on the auxin type used. NAA induced root differentiation whereas IAA added to media containing BA promoted adventitious shoot regeneration. Best results were obtained with 2.5 μM each of BA and IAA (19% of caulogenic explants). This reponse was increased (up to 44%) by varying nitrate to ammonium ratio from 2:1 to 4:1.
Micropropagation of juvenile and adult Sorbus domestica L.
1991
Successful propagation of seedlings and mature trees of Sorbus domestica L. has been achieved by in vitro methods. Multiple shoot formation was obtained by placing shoot apices or nodal segments on a modified Schenck and Hildebrandt medium containing benzyladenine. Regenerated shoots were excised and induced to root on media with auxin. In the best treatments 75–85% of shoots from juvenile material rooted. Rooting capacity of shoots from mature explants was lower (30%) and was not improved by dipping the base of shoots in concentration solutions of indolebutyric or naphthaleneacetic acids. Plantlets were ultimately established in soil.
