for one year. Alotgether, about 45 ~peete. were
recorded. DiatOllls were predOlllinant (27 specfes) IIIhfle
cyanophyte. (12 speetes) were less freqUent.
Chlorophytes (5 specfes) .nd rhodophytes (one specfes)
appeared .stly as r.re fOrlll. The highest frequency
of dfatOlls WlS fn the wfntfr .nd le.. in the other
seasons. For cy.nophytes. *hey were fl3re frequent
fn the s~r and autumn.
Results fndfcate that *he growth of epfphytes
on P. pectin.tu. was fnvers.lly correlated with the
