Summary

Pollen ofPinus silvestris shows a stimulation of germination and pollen tube growth after UV irradiation up to 3,6 erg/cm2. The UV irradiation must occur prior to or in the first 10 min after immersion of the pollen grains into the germination medium.

Stimulation occurs only if subsequent growth in visible light (1000 lx, fluorescent lamp) is allowed and can be suppressed by Actinomycin.
