INVESTIGATION ON THE DOMINANT SPECIES OF ICE NUCLEATION ACTIVE BACTERIA IN CHINA
我国冰核活性细菌的优势种类调查与研究

strains of INA bacteria were isolated from 68 species of plants in 17 provinces,cities and autonomous regions in China during 1986 to 1994. The identification results show that they belonged to 17 species(or pathovars)of 3 genera respectively.Among them,.133 strains are Erwinia ananas. accounting for 53.2%of total amount.The next group is Pesudomonas syingae pvs.The total is 70 strains,accounting for 28% of total amount.The other species of INA bacteria have 47 strains,accounting for only 18. 8% of total amount.Thus,the dominant species of INA bacteria in China is E.ananas,and then P.syringae pvs.grop.The dominance of E.ananas was more obvious in low latitude of southern areas.In high latitude of nouthern areas such as Beijing, Pseudomonas group was of a little dominance.INA bacteria of genera Xanthomonas were found mostly on family Gramineae plants in areas where the weather was more cold.
