Pollen taken from dehiscent anthers was examined by means of vital staining and cytochemical techniques in order to detect its viability; germination in vitro was evaluated. From the results obtained it is evident that saffron pollen is viable at a high percentage (65%) but germinates at a very low percentage. Moreover in vitro germination is very slow, and is accompained by numerous morphological anomalies. The low germination of the pollen is due to the triploidy of C. sativus.
