Developmental stages of potato (<i>Solanum tuberosum</i>) light sprouts in healthy plants and those infected with potato leaf roll virus (PLRV) have been distinguished. Potato light sprouts from healthy tubers differentiate in the early stages to the apical and basal parts, which are characterized by distinct dynamics of growth. Ultrastructural examination of apex meristem and phloem ontogeny was carried out for healthy plants. In the development of potato light sprouts of plants infected with PLRV a great many anomalies have been described. Three types of light sprouts developed from infected tubers. Anatomical investigations indicated a rapid growth of the number of necroses in the phloem, and submicroscopic observations showed the presence of virus particles and cytopathological structures: tubular and vesicular structures, paramural bodies and callose deposits. In the companion cells of the phloem the occurrence of very regular inclusions of virus particles was recorded.
