The bio-stimulating effects of invasive caulerpa Var. cylindracea extract on vignia sinensis and phaseolus vulgaris (Fabaceae)

Abstract

Caulerpa racemosa var. cylindracea is a biological pollution in the Mediterranean Sea because of its invasive character since 1991. No published eradication method exists in the scientific literature on this potential invader so far. The coastlines of 13 Mediterranean countries are under thread of Caulerpa racemosa var. cylindracea because of its impact on the biodiversity. The present study proposes an alternative evaluation of over produced biomass of Caulerpa racemosa var. cylindracea as seaweed fertilizer. The effect of seaweed extract on the growth and antioxidant system of Vignia sinensis and Phaseolus vulgaris seedlings were studied. Higher root and shoot lengths of V. sinensis were observed in extract supplemented groups (5%, 10% and 20%, p
