| Abstract:
Apricot chlorotic leaf roll (ACLR), associated with European stone fruit yellows (ESFY) phytoplasma, is one of the most important decline diseases of apricots in southern and central Europe. The paper surveys results of ESFY phytoplasma studies carried out during the period 1993–2003 in the Czech Republic. The special emphasis was devoted to apricots (Prunus armeniaca) as the most frequent and economically important host species of the phytoplasma. All of main apricot cultivars grown in the Czech Republic were found infected with ESFY phytoplasma. The ESFY phytoplasma was also identified in other hosts: Prunus persica, P. domestica, P. salicina x cerasifera, P. amygdalus x cerasifera, P. spinosa, Cerasus avium, and C. vulgaris. Psyllid Cacopsylla pruni was confirmed as a vector of ESFY phytoplasma. It was demonstrated that C. pruni is able to accomplish the regular development on three species of host plants: Prunus armeniaca, P. persica, and P. spinosa. | |
