Abstract

A survey of arbuscular mycorrhizal structures in bryophyte species was conducted. In total, 43 bryophyte species belonging to 29 families were studied. A search was made for hyphae and vesicles resembling structures of arbuscular mycorrhizal (AM) fungi in bryophytes. AM fungal structures (arbuscules, vesicles, hyphal coils nonseptate intra and inter celular hyphae) were found only in epigeous hepatics. AM fungal structures were absent in 21 moss species and recorded in only four of the studied 21 hepatics species and one of the hornworts. Other fungal structures were also observed. Fungal structures were observed in bryophyte stem and leaf tissues, and in rhizoids. The AM association with bryophytes was observed to be symbiotic.

Key words: arbuscular mycorrhizal fungi, bryophyte, hepatics, moss, symbiosis.
