The ligules of green leaves of cock's-foot grass, Dactylis glomerata L., are a micro-habitat for bacteria and fungi

Microbial populations on the ligule and leaf blade of cock's-foot grass, Dactylis glomerata L., were examined by three different methods. The ligule was identified as an important microbial niche for both bacteria and fungi. Microbial populations on the ligule increased after emergence and declined again as it approached senescence. The area of leaf blade adjacent to the ligule also had a rich microbial flora. This contrasts with the remainder of the leaf blade which is sparsely populated. However, the tip can also support a rich microbial population.
