ABSTRACT



The study covered field and pot experiments which involved 16 papilionaceous plant species under provocative conditions with artificial inoculation. The infection was performed about six weeks after sowing, spraying plants with the suspension of Colletotrichum gloeosporioides conidia from white lupin. The observations of the occurrence of the disease and the spread of infection were made every seven days. Over the technical plant maturity, sampling 4 x 50 plants of each of the sixteen species investigated for further research, and then making microscopic preparations, the presence of the pathogen was confirmed. There was determined the size of conidia derived from the plants species tested which were infected with C. gloeosporioides. In the pot experiment, at the emergence stage the plants were sprayed with the suspension of conidia of the pathogen. Over full maturity, 10 plants of each species researched were sampled from each of the 4 pots and there was determined the percentage of plants infected with the pathogen. Another aim of the pot experiments was to verify whether the isolates of C. gloeosporioides isolated from infected species of the plants tested remained pathogenic towards lupin. Out of the 16 species of papilionaceous plants investigated, 13 species were infected with lupin isolate of C. gloeosporioides. These species can then maintain their inoculation potential of the pathogen. Black medick, white melilot and soybean did not show disease symptoms.

Key words: anthracnose, Colletotrichum gloeosporioides, diseases, lupin, hosts range.
