Abstract

Throughout conducted investigations eight species of phytopathogenic micro-organisms in the bulb onion were detected. The local onion variety “Khatunarkh” is mainly infected with bacterial soft rot and rarely with gray and black rots (total infectivity -18.4 %) during the storage period, while the Russian onion variety “Karatalski” is mostly infected with black rot and more seldom with bacterial soft and gray rots (total infectivity -28.5 %). Unlike the bulbs of “Khatunarkh” local variety, those of the Russian variety “Karatalski” infected with bacterial soft rot and aspergillosis germinate prematurely during the storage time.
