Özet:

 


Two
endophytic bacteria, Bacillus subtilis SV41 (KR818071) and B.
amyloliquefaciens subsp.
plantarum SV65 (KR818073), were assessed under field conditions for
their capacity to control tomato Fusarium wilt in tomato and their effects on
soil microbial activity. Six months after planting, Fusarium wilt severity,
estimated through the vascular browning extent in tomato stems, was
significantly reduced by 82.3 and 88.2% compared to control following bacterial treatments. The frequency
of F.oxysporum re-isolation from roots, collars and stems was also
significantly lowered in treated plants compared to controls. These effects
were associated with a significant improvement, by 10.6 to 16.3%over control,
in plant height and root fresh weight and an increase in fruit production by
8.4-12.5%. As for microbial activity, F. oxysporum population in the
rhizosphere of tomato plants treated with B. subtilis SV41 and B.
amyloliquefaciens subsp. plantarum SV65 was reduced by
87.5-91.7%compared to the initial soil (sampled before planting) and by
88.4-92.3% relative to the rhizospheric soil of untreated plants (control
soil). A significant enhancement in the total culturable bacterial community
was also noted in the rhizosphere of tomato plants treated with both strains compared to initial and
control soils where a significant enrichment in Pseudomonas and
actinobacteria community was recorded.
