The apple blossoms frost damage decreased by biological control agents of INA+ Pseudomonas syringae

Popis výsledku v původním jazyce

We have concerned for selection of antagonistic bacterial strains reducing the population of ice nucleation active (INA+) Pseudomonas syringae (Ps) bacteria on apple blossoms with an aim of their possible use in biological control of fruit trees from frost injury. About 25 % of 71 screened bacterial strains produced antibiotic substances which inhibited the growth of INA+ strain Ps CCM 4073 in vitro. The selected antagonistic strains were non-pathogenic and also ice nucleation non-active (INA-). The three selected INA- antagonistic strains with the highest antibiosis in vitro were tested in experiments on detached flowering shoots of apple cv. Spartan in environmental chamber. Antagonistic strains induced freezing of 50% of separated flowers from 5.2to7.9 oC, however strain INA+ Ps CCM 4073 at 3.9 oC. The most effective INA- antagonistic strain lowered the supercooling temperature by 4 oC and consequently avoided frost injury of separated blossoms. However the blossoms connected with
