As in 2012, average maximum 10-day ETcvalues were recorded
during the maximum plant growth stages of the two species, only
to fall considerably during the second part of the mid-season stage,
with a decrease in average maximum values of as much as 37%.
During the late-season stage both macrophytes were found to have
average ETcvalues which were lower compared to 2012 for all of
the 10-day periods considered. It is of interest to note that, during
this stage, average ETaru values were lower by 3.3 mm/d than
2012 values whilst average ETcypvalues were lower by 2.8 mm/d
compared to the year before. Comparing the two results with
literature, there would seem to be many similarities. Regarding
giant reed, ETaruresults were similar to those found by
