Abstract
The effect of the pollination time and of the pollen origin was studied in three self-compatible and late-blooming almond genotypes in order to evaluate their effect on fruit set and yield. The full self-compatibility of the three genotypes was clearly assessed as fruit sets after self-pollination were similar to those obtained after cross-pollination with pollen from two different genotypes. Sets reached the level of a commercial production, ranging from 34.02% to 49.98% when the flowers were pollinated at the best pollination time, two days after emasculation. Pollination at later times significantly decreased fruit set, as well as high temperatures, negatively affecting stigma receptivity and, consequently, pollen germination and fruit set. Thus, early pollination is essential for self-compatible almond cultivars, mainly if these cultivars are grown in regions with warm conditions in late winter and early spring.
