| Popis: | The degree of resistance to ceratocystis canker (caused by Ceratocystis fimbriata Ellis et Halsted) in fig (Ficus carica L.) varieties ‘Zidi’ and ‘King’, which had been selected as vigorating rootstock, were compared with resistant variety ‘Celeste’ (‘Malta’ sensu Condit, 1995) and sensitive variety ‘Masui Dauphine’ (‘San Piero’ sensu Condit, 1955). 1. The leaf discs of each tested variety were inoculated with C. fimbriata by wounding. The lesions spread from inoculated points rapidly in ‘King’ and ‘Masui Dauphine’, moderately in ‘Zidi’ and slowly in ‘Celeste.’ 2. The suspension of C. fimbriata was injected to the pot soils growing nurseries of each tested variety. The lesions appeared and C. fimbriata was reisolated from the nurseries of every variety. The mortalities for 90 days of inoculated nurseries were higher in ‘King’ (89%), ‘Zidi’ (64%) and ‘Masui Dauphine’ (62%), and lower in ‘Celeste’ (6%). These results suggested that the degree of resistance to ceratocystis canker was lower in vigor fig varieties ‘Zidi’ and ‘King.’ |
