Optimal conditions forin vitrogermination and tube growth ofLimonium perezii(Plumbaginaceae) pollen were established. Boric acid, calcium nitrate, casein hydrolysate and sucrose were all important medium components. A dialysis tubing & filter paper support combined with using polyethylene glycol as an osmoticum in the medium provided appropriate physical conditions forL. pereziipollen germination. Anin vitropollen germination rate of about 40% was achieved. The longest pollen tube observed was four times the pollen grain diameter.
