Abstract: The associations ‘Marcona’-‘Fournat de Brézenaud’ and ‘Ferragnès’-‘Ferraduel’ are the cultivar combinations mostly planted in commercial almond orchards in Morocco. The blooming times and effective pollination period (EPP) were determined for these associations to determine the effect of blooming and pollination times on the irregular yields observed in Morocco with these cultivars. ‘Marcona’ bloom was earlier than that of ‘Fournat de Brézenaud’, but ‘Ferragnès and ‘Ferraduel’ coincided. Fruit set and percentage of pistils with pollen grains was maximized when pollination occurred at day 2 after emasculation. Fruit set and stigmatic receptivity decreased drastically by day 4 after emasculation. Fruit set in the open pollination treatment was lower than that obtained after hand pollination at days 0 and 2 after emasculation, especially in ‘Marcona’. These results emphasize the importance of early pollination and the selection of new cultivars with the same flowering period as ‘Marcona’ to improve almond yields in Morocco.
