Abstract
The paper presents the results of a study regarding the influence of treatment with zinc (as sulphate solutions) in different concentrations (50 mg∕l, 100 mg∕l, 200 mg ∕l, 300mg/l, 400 mg ∕l, 500 mg/l, 600 mg ∕l and 800mg ∕ l) on the seed germination and the growth in early ontogenetic stages of Salvia coccinea. We analyzed the following indicators: the percentage of germinated seeds at different intervals (24 - 168 hours); the length of root and hypocotyl (at 168 hours). The results underline the specific variations of the analysed indicators, depending on the concentrations used for the treatments of seeds. The treatment with zinc sulphate solution with concentration of 100 mg/l presents a tendency of stimulate the germination (with 10 % compared to control). The effect on growth varies depending on the concentration. A delay effect of growth in length of the root and hypocotyls and an inhibitory effect was found (very high concentrations inhibit the growth).
