摘要

对山东茶树上冰核细菌的种类和分布规律及消长动态进行了研究,结果表明：在山东茶树上可分离得到泛菌属两个种的冰核细菌,分别为菠萝泛菌（Pantoea ananatis）、成团泛菌(Pantoea agglomerans)。分离到的22株冰核细菌中,冰核活性最强的是8号和11号。茶树上不同部位存在的冰核细菌的密度和频率不同,初展叶(芽)上分离得到的冰核细菌的密度最高,也较易分离得到,其次为嫩叶和老叶;茶树品种和不同的茶树栽培区域同样也会影响冰核细菌的分布,如在青岛地区分离的冰核细菌的密度大于泰安地区,不同品种上存在冰核细菌的密度也不同。此外,在雨水较多、湿度较大的季节茶树上冰核细菌的密度较高,而在干燥寒冷的时候则较难分离得到冰核细菌。

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
