Cryopreservation of shoot tips of blackberry and raspberry by encapsulation-dehydration and vitrification.
Encapsulation-dehydration and PVS2-vitrification cryopreservation protocols were evaluated for the long-term conservation of a diverse group of Rubus germplasm. Cold acclimation for a 4-week period prior to cryopreservation was necessary for regrowth of shoot apices from blackberry and raspberry genotypes. For the encapsulation-dehydration protocol, encapsulated apices were pretreated in 0.75 M...
متن کاملCryopreservation of Capparis spinosa Shoot Tips via Vitrification, Encapsulation Dehydration and Encapsulation Vitrification
In vitro shoot tips of Capparis spiunosa were cryopreserved using the vitrification, encapsulation/ dehydration and encapsulation vitrification techniques. In the vitrification procedure, a maximum of 70% regrwoth was obtained when shoot tips were treated with the Plant vitrification solution (PVS2) for 60 min at 0°C and plunged directly into liquid nitrogen. In encapsulation dehydration, shoot...
متن کاملCryopreservation of Potato Shoot Tips
Potato is one of the most important staple crops in both developed and developing countries of the world. Potato genetic resources are a prerequisite for potato breeding in both conventional and genetic engineering programmes. Cryopreservation has long been considered an ideal means for the long-term conservation of plant genetic resources. This review provides comprehensive information on vari...
متن کاملCryopreservation of in vitro-grown shoot tips of cassava by encapsulation-vitrification method.
Shoot tips of cassava (Manihot esculenta Crantz) in vitro plantlets were successfully cryopreserved using the encapsulation-vitrification technique. Nodal cuttings of 5 mm length with one leaf were cultured on modified MS medium in Petri dishes (90 mm x 20 mm) for about 28 days. Excised shoot tips were precultured on sucrose enriched (0.3 M) medium for 16 h, encapsulated and osmoprotected with ...
متن کاملStrigolactone regulation of shoot branching in chrysanthemum (Dendranthema grandiflorum)
Previous studies of highly branched mutants in pea (rms1-rms5), Arabidopsis thaliana (max1-max4), petunia (dad1-dad3), and rice (d3, d10, htd1/d17, d14, d27) identified strigolactones or their derivates (SLs), as shoot branching inhibitors. This recent discovery offers the possibility of using SLs to regulate branching commercially, for example, in chrysanthemum, an important cut flower crop. T...
