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. |

Natural pastures has a high variability in different landscape scales. In the Santa Catarina
highlands soil factors as shallow soils, rock outcrop, high land slopes, and low soil fertility are
someone of vegetation conditioning factors in each location. The improvement of natural
pastures with the correction of soil fertility and oversowing of cool-season species is a
commonly alternative used by local producers. The aim was to study the plant community in
natural and naturalized pastures with human intervention. It was evaluated phytosociology
parameters in ranch properties in the municipalities of Lages, São Joaquim, Painel, Capão Alto
and Bom Jardim da Serra with improved natural pastures and in São José do Cerrito with
improved naturalized pastures. The improvement is with correction of soil fertility based on soil
analysis. The species introduced were: rye (Secale cereale) oat (Avena sativa), annual ryegrass
(Lolium multiflorum Lam), white clover (Trifolium repens), red clover (Trifolium pratense),
dactyl (Dactylis glomerata) meadow soft grass (Holcus lanatus) and birdsfoot trefoil (Lotus
corniculatus). Five sample units (SU) of 1m were established in each local in January 2014. It
was calculated the values of species presence/absence, absolute percentage of soil coverage and
relative coverage. The Shannon Index was calculated using software "R" (vegan package). The
survey identified 147 species, the greater species richness were observed in São Joaquim with 27
species / SU, Bom Jardim da Serra with 24 species / SU, Capão Alto presented 23 species / SU,
Lages and Painel presented 21 species / SU. The improved naturalized pasture in São José do
Cerrito presented the lowest value with 12 species / SU. Shannon diversity index in São Joaquim
was 2,745, Bom Jardim da Serra 2,052, Capão Alto 2,402, Lages 2,630 and Painel 2,470. In São
José do Cerrito Shannon index was 2,051. The introduced and native species represent 12.18%
and 13.66% of relative soil coverage, respectively. The ten species with the greatest contribution
was: Trifolium repens L., Trifolium pratense L., Lotus corniculatus L., Holcus lanatus L., and
the native species was Axonopus compressus (Sw.) P. Beauv, Paspalum plicatulum Michx.,
Paspalum notatum Flügge, Hypoxis decumbens L., Cyperus hermaphroditus (Jacq.) Standl., and
P. dilatatum Poir. Improvements of natural pastures presents higher plant diversity than
