Contribution to better knowledge of the quality of pomegranate pollen (Punica granatum L.).

Summary

The aim of the work was to determine the reasons for low fertilization in some pomegranate cultivars. The cultivars studied were ME5, ME16 and ME17 cultivated under homogeneous conditions in the collection grown at Escuela Politécnica Superior of Orihuela (EPSO). The investigation was carried out during 1996 and 1997. Pollen viability was studied with acetic carmine dye weekly throughout flowering. This parameter was also studied in pollen that had been conserved at 5 and 28 °C. Germination ability was researched with pollen of male and hermaphrodite flowers grown in a culture medium at 15 and 28 °C which were observed 24 and 48 hours after sowing. Different pollination types were studied (natural, anemophilous, entomological and self-pollination). The stigma receptivity period, ranging from two days before anthesis to four days after it, was also determined. To summarise, it could be deduced that there are different flowering abilities and effective pollination types. It was also confirmed that lower temperature conservation allowed pollen to be conserved for longer, and the effective pollination period varied from anthesis up to three days later.
