Pollen viability varies with temperature and humidity; cereal pollen (rice, wheat) loses viability within 30 minutes, while pollen from some Rosaceae, Leguminoseae, and Solanaceae members remains viable for months.
Il periodo per cui i granuli pollinici rimangono vitali è molto variabile e dipende in parte dalla temperatura e dall'umidità prevalenti. In alcuni cereali come riso e grano, i granuli pollinici perdono vitalità entro 30 minuti dal loro rilascio, e in alcuni membri di Rosaceae, Leguminoseae e Solanaceae, mantengono la vitalità per mesi.
