In this research , the effect various temperatures was studied on pollen tube dynamics in in vitro and controlled conditions ‘Nec Plus Ultra, ‘Sahand, and ‘Ferragnes, almond cultivars and ‘K100’ genotype. The collected pollens were cultured in a suitable medium. Cross-pollinations were performed in the chambers at different temperatures. Germination and pollen tube growth were studied at different temperatures. Results showed significant differences among the studied cultivars and genotype in different temperatures for pollen germination and pollen tube growth. The highest percentage of pollen germination in in virto condition and under controlled condition was observed in ‘Sahand’. The highest percentage of pollen tube at style base was observed in ‘Nec plus ultra’
