To optimize the pollen germination medium, pollen from ‘Hass’,
the commercially most important avocado cultivar worldwide, was
used. Flowers in the male stage were collected from the field immediately
after anther dehiscence and maintained at 100% RH during
2h
We used as basic medium that reported by Sahar and Spiegel-
Roy (1984). The experimental design aimed at evaluating the
effect of sucrose, polyethylene glycol (PEG), MgSO4·7H2O and
Ca(NO3)·4H2O on the percentage of pollen grain germination and
bursting.
