  abstract = {{M}editerranean shrublands are generally water-limited and fire-driven ecosystems. {S}eed-based post-fire regeneration may be affected by varying rainfall patterns, depending on species sensitivity to germinate under water stress. {I}n our study, we considered the germination response to water stress in four species from several sites across the {M}editerranean {B}asin. {S}eeds of species with a hard coat ({C}istus monspeliensis, {C}.salviifolius, {C}istaceae, {C}alicotome villosa, {F}abaceae) or soft coat ({E}rica arborea, {E}ricaceae), which were exposed or not to a heat shock and smoke (fire cues), were made to germinate under water stress. {F}inal germination percentage, germination speed and viability of seeds were recorded. {G}ermination was modelled using hydrotime analysis and correlated to the water balance characteristics of seed provenance. {W}ater stress was found to decrease final germination in the three hard-seeded species, as well as reduce germination speed. {M}oreover, an interaction between fire cues and water stress was found, whereby fire cues increased sensitivity to water stress. {S}eed viability after germination under water stress also declined in two hard-seeded species. {C}onversely, {E}.arborea showed little sensitivity to water stress, independent of fire cues. {G}ermination responses varied among populations of all species, and hydrotime parameters were not correlated to site water balance, except in {E}.arborea when not exposed to fire cues. {I}n conclusion, the species studied differed in germination sensitivity to water stress; furthermore, fire cues increased this sensitivity in the three hard-seeded species, but not in {E}.arborea. {M}oreover, populations within species consistently differed among themselves, but these differences could only be related to the provenance locality in {E}.arborea in seeds not exposed to fire cues.},
