Pseudomonas syringae influence on winter wheat yield

The last year research shows that pathogenic bacteria Pseudomonas syringae which cause leaf blight and basal glume blotch are spreading in Lithuania. loss of grain yield because P. caused diseases might be from 5 to 50%. decrease depends on many factors, including environment conditions (especially temperature humidity). aim the study is identity how different strains infection influence winter wheat (Triticum aestivum) In vitro five varieties (Dagmar, Janne, Edvins, Skagen Artist) have been infected by cell suspensions eight (1.0 × 106 KSVml–1) growth stages (BBCH 61, BBCH 63-65, 70- 71 75). has sprayed sterile distilled water control variant. Grain weight differences between investigation variants estimated after achieved full maturity (BBCH89). With reference analysis data three statistical factors we can say time did not a significant (P = 0.1970), but was statistically 0.0000). interaction such as varieties, well significant. referential pv. (strain No. CFBP 4108 Van Hall 1902) Atrofaciens 3587 Mac Culloch 1920) reduced mostly 0.0000), respectively, 10.2 9.1% compared control.
