Abstract
The paper presents the results of a study regarding the influence of treatment with zinc on seed germination and seedlings growth of Dianthus chinensis L. Zinc used were as sulphate solutions in a concentration of 50 mg ∕ l 100 mg∕ l; 200 mg ∕ l; 400 mg ∕ l ; 600 mg ∕ l and 800mg∕ l. We analyzed the following indicators: the percentage of germinated seeds in 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 seed treatments. The treatments with zinc sulfate delay the growth of the root (with concentration of 100 mg∕ l; 200 mg ∕ l; 400 mg ∕ l; 600 mg ∕ l and 800mg∕ l.) and hypocotyl (all the concentration used). The delay effect on the hypocotyl and root length growth is very pronounced in the case of variant treated with high concentrations.
