Deposition of callose in wound tissue tuber of potato (Solanum tuberosum L.)

Abstract

Fluorescent methods were used for investigation of callose deposition in cells of wound tuber tissue of potato. Potato cultivars: Tarpan, Certa and Narew were examined. Deposition of callose in cells depended on the place of the wound, type of tissue and cultivar of potato. The apical part deposited more callose than the base part and the primary bark more than the pith crown. More callose was deposited in Tarpan, less in Certa, least in Narew. The quantity of the callose corresponded to the resistance to store diseases i.e. fungal dry mixed rots. As the temperature during storage and healing of the wounded tuber was declined, the quantity of callose after injury decreased.
