Other claims from this paper (8)
- Observation Corn-leaf Erwinia suspensions nucleated ice at –2.3 C and below.
- Observation Growth on glycerol-supplemented agar enabled nucleation at –2.3 C.
- Intervention effect Sprayed corn seedlings were severely damaged at –4 C, unlike controls.
- Intervention effect Freezing within six hours of spraying produced frost damage statistically similar to controls.
- Association Frost damage rose as incubation time increased from 12 to about 36 hours.
- Association Frost damage at 48 hours increased with applied bacterial density.
- Observation Erwinia populations multiplied from about 3 × 10 3 to about 5 × 10 6 cells/g by 36 hours.
- Association Probit frost injury was directly proportional to log Erwinia population.
