S. vermifera induces germination of N. attenuata by inhibiting ethylene production. Mean + se germination rate of wild type and ir-aco N. attenuata seeds on S. vermifera-inoculated (black bars) and uninoculated (white bars) plates with and without the ethylene scrubber KMnO4. The number of germinated seeds was determined 7 d after sowing. Asterisk indicates significant difference in germination between inoculated and uninoculated seeds within one genotype of each treatment (t test, P < 0.05).
