| Abstract: | A new research field about INA bacteria has been studied in China Since 1986.Some new discoveries and progresses have been achieved. In this paper we would make a brief summary on the following results of our studies have been found out. The species and their distribute on pattern, and the intensity of ice nucleation activity have been investigated. Methods proposed for the preservation of INA bacteria among INA bacteria, low temperature and frost injury of plant, proved that INA bacteria is an important factor in inducing and enhancing frost injury of plant. A new method for chemical and biological control of frost injury has been studied. With the application of INA bacteria, an ice protein snowmaking catalyst has been successfully developed. Our studies are also concerned about the insect pests control by accelerating their frozen point with INA bacteria, and the biological aspects of the applied technology concerning INA bacteria. The first report of BYDV acting as ice nucleation in our studies is of certain significance in the uncovery of the unkown biological ice nucleation. |
