In vitro axillary buds of two apple cultivars, Pinova and Jonagold, were successfully cryopreserved by droplet-vitrification. In vitro axillary buds of cv. Pinova were subjected to PVS2 for 15, 30, 45, 60, 80 or 100 min, while Jonagold buds were treated with PVS2 for 15, 30, 45 or 60 min. In addition, the effect of age of in vitro mother-plants on recovery(More)

A culture medium for shoot-tips growth was established using the Woody Plant Medium supplemented with 2.22 uM 6-benzylaminopurine. Excised shoot-tips were subjected to(More)

Genetic risk factors, especially inherited deficiencies in coagulation inhibitors, also play a role in the pathogenesis of(More)
