  abstract = {{A}queous seaweed extracts are a biological product which have beneficial effects on plant growth as well as improving their resistance to several biotic and abiotic stresses. {T}his work aimed to evaluate the effect of aqueous extracts of three seaweeds {F}ucus spiralis, {C}ystoseira ericoides ({P}haeophyceae) and {U}lva lactuca ({C}hlorophyceae) harvested from {A}tlantic coast of {R}abat region in {M}orocco, on lead ({P}b) tolerance and accumulation in tomato ({S}olanum lycopersicum) plants. {A}queous extracts were obtained by the combination of 2 extraction processes, ultrasonication and heating. {T}he brown seaweeds {F}. spiralis and {C}. ericoides extracts had good antioxidant activity in the {DPPH} assay. {T}he growth and physiological parameters were compared between {S}olanum lycopersicum seedlings grown in hydroponic conditions at 0 and 100 mu mol {P}b with or without 4% seaweed extract. {T}he {F}. spiralis and {C}. ericoides extracts significantly increased the aboveground parts and roots biomass compared to control plants treated with {P}b alone. {I}n {P}b stress conditions, these seaweed extracts enhanced the plant's tolerance with a reduction of anthocyanin and proline content. {F}. spiralis extract treatment led to a significant {P}b accumulation in aboveground parts of the plant. {T}he effect of {U}. lactuca extract on tomato plants biomass, anthocyanin and proline was not significant. {T}he study demonstrated that the aqueous extracts of {F}. spiralis and {C}. ericoides improved the plant response to heavy metals stress, highlighting the potential use of these seaweeds in phytoremediation processes.},
