e0“Inoculated plantlets of cultivars Norchip, Kennebec, Shepody, and Chaleur showed, in root dry weight, a five- to eight-fold increase, two- to three-fold increase, no response, and a decrease of 50%, respectively.”
e1“growth promotion of potatoes by strain PsJN was cultivar specific”

Other claims from this paper (10)
- Method / resource The gnotobiotic potato bioassay was highly useful for testing growth promotion by PsJN.
- Intervention effect PsJN increased root dry weight five- to eight-fold in Norchip.
- Intervention effect PsJN increased root dry weight two- to three-fold in Kennebec.
- Intervention effect Shepody root dry weight did not respond to PsJN inoculation.
- Method / resource Haulm dry weight followed root trends but was less consistent as an indicator.
- Method / resource Minor medium, temperature and light changes did not materially change bioassay results.
- Method / resource Screening eliminated 93% of transconjugates retaining growth-promotion activity.
- Method / resource Seven retested isolates were confirmed to have lost growth-promoting ability.
- Intervention effect Other bacterial genera did not increase potato plantlet growth.
- Intervention effect Several other bacterial isolates inhibited potato root and haulm growth.
