| Abstract:
Under the heat treatment conditions typically used for virus therapy, sweet cherry tree (Prunus avium) growth and survival improved drastically when the trees were grown by hydroponics. This culture system allowed for extended heat treatment times that were sufficient to reduce levels of Prunus necrotic ringspot ilarvirus and prune dwarf ilarvirus in growing shoots of infected trees. The effectiveness of the heat treatment was further enhanced by the addition of antiviral compounds to the hydroponic nutrient solution. | |
