Pollen ultrastructure of twenty almond cultivars

, : Pollen ultrastructure of twenty almond cultivars. Advances in Horticultural Science 2(3): 88-95

Pollen size and exine ultrastructural studies were undertaken using scanning electron microscopy on 50 grains from 3 trees each of 20 Prunus dulcis cultivars. Pollen grains of all the cultivars, in equatorial view, were elliptical-truncate, isopolar, trizonocolpate and possessed a striated exine with minute pits (fovi). Grain length was more highly variable within cultivars than grain width, ranging from 60.1 (Pizzuta D'Avola) to 67.1 micro m (Tuono).
