Lack of stolbur transmission by seeds in some moldavian tomato and pepper varieties

Abstract

The study of the possibility of stolbur transmission by seeds in some Moldavian tomato and pepper varieties was carried out using molecular diagnostic methods. The lack of the transmission of phytoplasma by seeds was evidenced analysing seedlings growing in the controlled laboratory conditions (thermostat) when the infection by insect vectors was impossible. Moreover, this lack was confirmed by results showing the absence of ‘Ca. P. solani’ infection in plants analyzed in mid-July of 2020 (stages of ‘flowering’ or, mainly, ‘green fruits’) grown in the field or greenhouse.
