Abstract

Petagnaea gussonei (Apiaceae) is a perennial herbaceous species endemic to northeastSicily (Nebrodi Mountains). It is considered a remnant of the Sicilian Tertiary flora,and is endangered according to the Red List. There is no information in the literatureabout the germinability of its seeds, even though seed production is know to occur.The aim of this study was to obtain data to better understand seed germination of thisspecies and its biological implications. Thus, several approaches were employed: vitalityanalyses, gibberellic acid supply, germination and soil microbial flora analyses viaend-point and qPCR. The results suggest that seed germination occurs after ca.1.5 years at a rate of ca. 11%. The seeds can be classified as physiologically dormant,and probably require prolonged cold stratification for germination. Because seed germinationis low, it is likely that agamic reproduction represents an important meanfor its conservation and survival. These results have important implications forP. gussonei survival and should be considered in possible re-introduction attemptsaimed at restoring threatened populations.
