Chamaerops humilis L. commonly named dwarf fan palm is native to the Mediterranean Region. The plant exhibits a shrub habit, either acaulescent or bearing multiple stems, up to 2 m tall, covered with fibres and the remains of leaf petioles. When cultivated the plants can reach 6-8 m height. Leaves are persistent, fan-shaped, rigid and erect, borne on long and slender petioles armed with lateral spines; the lamina is split into 16-20 pointed segments (AA. VV. 1954). In Sicily this palm is naturalised and widely used, in the past, for various kind of wickerwork, and as ornamental in most of the historical villas of the region. The species is now used for public and private gardens design. The aim of this research was: 1) to test various substrates for in vivo germination and 2) to test concentrated sulfuric acid (H 2SO 4) at different times to improve in vitro germination. Seeds germinated in the peat-perlite substrate, had a better vegetative response. Seeds dormancy was efficiently broken by the sulfuric acid scarification as 10 min treatment produced the best response (50% of germination in approximately 31 days).
