| Research Abstract |
There are many unculturable bacteria in environment, for example, ca.99% of bacteria in soil have been reported to be unculturable. However, little is known about bacteria on plant surface. In this study, the rapid and simple counting method of total bacteria on plant surface was developed and the populations of culturable (A) and unculturable (B) bacteria on the leaf surface of crops (rice and wheat) were assessed by the developed counting method and agar medium. The proportions (A/B) of their bacteria of rice and wheat before heading time were about 1/10 and 1/1000, respectively, indicating the significant difference in the proportion(A/B) among the two crops. The results suggest the dynamic change in the proportion of culturable bacteria on leaf surface among crops.
