Effect of soil water content and temperature on the transmission of Pseudomonas syringae pv. pisi from pea seed (Pisum sativum) to seedling

Effect of soil water content and temperature on the transmission of Pseudomonas syringae pv. pisi... The effect of soil water content on the transmission of Pseudomonas syringae pv. pisi from pea seed (cv. Buckley) to seedling in field soil was investigated in controlled environment rooms maintained at 5°C and 15°C. Artificially inoculated seed was sown in soils of various water contents, and the seedlings tested for the presence of P. syringae pv. pisi using an ELISA based test. Soil water content had a significant effect on the transmission of the bacterium from seed to seedling. Transmission was reduced, but not prevented, at low soil water contents. The effect of temperature on transmission was marginally non-significant (P=0.056). Since transmission off! syringae pv. pisi still occurred at low soil water content it is unlikely that sowing into a dry seed bed can be used to prevent transmission of P. syringae pv. pisi from seed to seedlings. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Australasian Plant Pathology Springer Journals

Abstract

The effect of soil water content on the transmission of Pseudomonas syringae pv. pisi from pea seed (cv. Buckley) to seedling in field soil was investigated in controlled environment rooms maintained at 5°C and 15°C. Artificially inoculated seed was sown in soils of various water contents, and the seedlings tested for the presence of P. syringae pv. pisi using an ELISA based test. Soil water content had a significant effect on the transmission of the bacterium from seed to seedling. Transmission was reduced, but not prevented, at low soil water contents. The effect of temperature on transmission was marginally non-significant (P=0.056). Since transmission off! syringae pv. pisi still occurred at low soil water content it is unlikely that sowing into a dry seed bed can be used to prevent transmission of P. syringae pv. pisi from seed to seedlings.
