| Abstract:
The most characteristic symptom of apricot bare twig and unfruitfulness - besides the lack of fruit - is the change of tree habit. As the disease progresses the short lateral fruit branches dry, die and fall off. Virus was mechanically transmitted to Cucumis sativus, Chenopodium quinoa, C. amaranticolor which showed very characteristic symptoms. Infected apricot seedlings showed stunting and slight leaf mottling. The peaches showed a typical shock stunting and a characteristic loss of apical dominancy. Mechanical inoculations to very young apricot and peach seedlings were successful with isolates of strawberry latent ringspot virus and cucumber green mottle mosaic virus from diseased apricots obtained by CECH et al. (1980). | |
