The effect of zincon germination and seedlings growth of Eruca sativa Mill.

Abstract

The effect of zinc on seed germination and growth in the first ontogenetic stages in the species Eruca sativawasinvestigated.Zinc was used as sulphate solutions, in five different concentrations:50 mg/L, 100 mg/L; 150 mg/L, 200 mg∕L; 250 mg∕L.We analyzed the following indicators: the percentage of germinated seeds; the length of root, the length of the hypocotyl, thetolerance index, the seedling vigor index, water content and dry matter content of the seedlings.The following effects were found: the insignificant modifications of the germination percentage; the significant delay of the growth in length of the root and of the hypocotyl; the decrease of the tolerance index, of the seedling vigor index and of the water content.
