Estimated nectar sugar yield and pollen yield (± SD) delivered per plant of the studied species. Mean values are presented for 2014 and 2015, and means from four plants of each species were calculated. Different letters indicate significant differences among the species and between the years of study (italics), separately for nectar sugar yield (capital letters) and pollen yield (small letters), (post-hoc HSD Tukey test, p < 0.05).
