Abstract

Abstract: The species, distribution and the dynamic changes of Ice Nucleation-Active (INA) bacteria in tea garden of Shandong province were investigated by the authors. Results showed that there are two species of INA bacteria (Pantoea ananatis and Pantoea agglomerans) existed on tea plant of Shandong province. Among the isolated 22 strains of INA bacteria, No.8 and No.11 have the strongest ice nucleation activity. Different frequency and density of INA bacteria were showed in the different parts of tea plant. The density of the INA bacteria was highest on the tea bud, then the tender leaf and the old leaf successively. The different cultivars and different distributive location of tea plant will also influence the distribution of INA bacteria. Investigation showed that the density of INA bacteria isolated from the Qingdao region is higher than that in Tai-an region. Besides, it is easier to isolate the INA bacteria in the spring and autumn season with more rain and higher humidity than that in cold and dry winter season.

Key words: tea plant, Ice Nucleation Active (INA) bacteria, Shandong province, distribution rule dynamic changes
