ABSTRACT
Plant pathogenic bacteria particularly of the Pseudomonas syringae group have been reported to possess an ice-nucleation property (Gross et al., 1983). Ice-nucleation is the ability of bacteria to convert water molecules or dew molecules into the ice at a temp above 2°C. Generally these bacteria convert water molecules into ice at a temp of 3–4°C. These bacteria are generally prevalent in temperate regions of the world. They are present on the plant parts and increases the damage caused by frost by their ice-nucleation activity.
