Several aspects of pomegranate flower biology are addressed. Clones PTO1, PTO2, ME14 and ME15 were used in the study, all of them Spanish cultivars from the provinces of Murcia (the first two) and Alicante (the latter two). Pistil receptiveness was assessed by the "fruit set" method. Selected flowers were emasculated and later pollinated with either their own or foreign pollen grains from other cultivars; afterwards fruit set was quantified. Likewise, effective pollination time was also calculated. While all pomegranate clones showed a pistil receptiveness of seven days, ME15 yielded a receptiveness of just six days. The highest fruit set percentage was achieved one day before anthesis and two days after. Clone ME15 yielded an effective pollination time (EPT) of four days, whereas the others (PTO1, PTO2 and ME14) showed an EPT of five days.
