Induction of Systemic Resistance of Cucumber to Colletotrichum orbiculare by Select Strains of Plant Growth-Promoting Rhizobacteria
Abstract
Ninety-four strains of plant growth-promoting rhizobacteria (PGPR) were screened for induction of systemic resistance using a model system of cucumber and anthracnose, caused by Colletotrichum orbiculare. Compared with a nonbacterized, challenged control, treatment of cucumber seeds with six PGPR strains resulted in a significant reduction in lesion size after challenge-inoculation with C. orbiculare. Four of the six PGPR strains that induced resistance in cucumber produced HCN in vitro. Antagonism in vitro toward Pythium ultimum, Rhizoctonia solani, and C. orbiculare on three media generally was absent with five PGPR strains and weak with one strain. Rifampicin-resistant mutants of the PGPR strains colonized roots at mean population densities of log 6.5 to 8.3 cfu g(-1) of root at 7 days after planting and log 4.1 to 6.1 cfu g(-1) at 21 days after planting. None of the strains was recovered from surface-disinfested petioles on the day of challenge with C. orbiculare. Roots from plants bacterized with PGPR strains showed less necrosis than the nonbacterized, challenged control. The results support the conclusion that some PGPR strains applied to seed can induce systemic resistance to C. orbiculare

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
