In order to analyze the pathogenicity and antagonism between grapevine rootstocks and
soil microorganisms, plant growth-promoting bacteria with antibiotic effect were selected from the
phytopathogen Ilyonectria liriodendri, 2T-VSC-101 isolated monosporic, in in vitro antibiosis tests.
The bacterial access that produced the largest zone of inhibition was used in the seedling biotization
of the grapevine rootstocks P1103, IBBT481 and VR039-16. From the interaction between isolates
of plant growth-promoting bacteria and Ilyonectria liriodendri isolate resulted in three bacterial
isolates with control of the mycelial growth of the phytopathogen, all of the Burkholderia gender.
However, the highest control bacterium, Burkholderia catarinensis sp. nov. isolated POA 89, was
found to be detrimental to the in vitro development of rootstocks, causing them to die. The cultivation
through culture medium modifed with sand was adequate for the in vitro growth of the rootstocks
and appropriate for the observation of the black foot disease?s characteristic symptoms. From the ex
vitro cultures with the IBBT481 rootstock and the microorganisms, there were results in favorable
effects to the plants inoculated with the bacterium in combination with the phytopathogen. It also
demonstrated the diffculty of acclimatization and growth of this access in a greenhouse. |
