Effects of temperature on multiplication of Pseudomonas syringae pv. savastanoi (Smith) Young et al.
In tests using colony counts and transmission ratios with isolates from olive, privet and oleander, multiplication was best at 22°-25°C, good at 18°-28°, and low less than 18° or more than 33°. Olive isolates reached transmission ratios of 1-2% later than those from privet and oleander. Possible correlations involving thermal characteristics are examined.
