  • analysis of chemical and structural changes in kiwifruit Actinidia deliciosa cv hayward through the osmotic dehydration
    Journal of Food Engineering, 2011
    Co-Authors: Marta Castrogiraldez, P Fito, Urszula Tylewicz, Dalla M Rosa


    Abstract Osmotic dehydration experiments of kiwifruit ( Actinidia deliciosa cv Hayward ) were carried out in order to apply a nonlinear irreversible thermodynamic model. Samples were immersed into 65% (w/w) sucrose aqueous solution at 30 °C during 5, 10, 15, 20, 30, 45, 60, 90, 120, 180, 250, 320, 400, 720, 1440 min. Some physical–chemical parameters were measured in fresh, treated and reposed (24 h at 30 °C) samples. It was possible to apply the enthalpy–entropy compensation coupled to a nonlinear thermodynamic model, obtaining the apparent bulk modulus and explaining the elastic answer of the tissue throughout the osmotic process. The osmotic dehydration also produces losses in the native compounds of kiwifruit such as citric acid and Calcium and Potassium.

  • increase of rooting ability in the woody species kiwi Actinidia deliciosa a chev by transformation with agrobacterium rhizogenes rol genes
    Plant Cell Reports, 1991
    Co-Authors: Eddo Rugini, Alessandro Pellegrineschi, Massimo Mencuccini, D Mariotti


    The woody species kiwi (Actinidia deliciosa A. Chev.), a male and late flowering clone of the cv Hayward, has been transformed by a T-DNA fragment encompassing rol A, B, C genes of A. rhizogenes. Transgenic plants, regenerated from leaf disc callus, showed the typical “hairy root” phenotype as described in herbaceous species. Explants from these plants (both leaf discs or 3 to 4 node leafy microcuttings) showed an increased ability to produce roots. Since root formation is one of the limiting factors in the vegetative propagation of woody species, the results have been discussed in relation to the use of A. rhizogenes rol genes in improving root morphogenesis in trees.

  • Somatic embryogenesis in leaves and leaf-derived protoplasts of Actinidia deliciosa var. deliciosa cv. Hayward (kiwifruit)
    Plant Cell Reports, 1992
    Co-Authors: M. Margarida Oliveira, M. Salomé S. Pais


    The obtention of embryogenic competence in Actinidia deliciosa var. deliciosa cv. Hayward is reported. Axillary buds from shoots submitted to cold (4°C) and starvation for 1.5 months, developed leaves with embryogenic competence. These leaves, cultured in darkness for 1.5 months on a medium containing zeatin as a sole growth regulator, originated compact structures from which embryos developed. The plating orientation and sectioning of leaves strongly affected the expression of the embryogenic potential. A selected fraction of the protoplasts isolated from these leaves was able to develop in an embryogenic way. The germination of the embryos is still only occasional.

  • Plant regeneration from protoplasts of long-term callus cultures of Actinidia deliciosa var. deliciosa cv. Hayword (Kiwifruit).
    Plant Cell Reports, 1991
    Co-Authors: M. Margarida Oliveira, M. Salomé S. Pais


    Plant regeneration of Actinidia deliciosa var. deliciosa cv. Hayword was obtained from protoplasts isolated from petiole derived long-term callus cultures. Protoplasts were cultured in liquid medium over agarose gelled medium. Regenerated green callus, plated on solid medium, could develop shoots that rooted spontaneously in hormone-less medium. The plants obtained are growing fast in soil and present a normal phenotype.
