The paper presents the results of a study regarding the influence of treatment with zinc in different concentrations (50 mg∕l, 100 mg∕l, 200 mg ∕l, 300mg/l, 400 mg ∕l, 500 mg/l, 600 mg ∕l) on seed germination and growth in early ontogenetic stages of Cucumis melo L. We analyzed the following indicators: the percentage of germinated seeds; the length of root, the length of the hypocotyl and the length of the seedling; the number of the laterale roots; the tolerance index and the seedling vigor index. The results underline the specific variations of analysed indicators, depending on the concentrations used for the treatments of seeds. The concentrations used for treatment do not influence negatively the seed germination, but affected the seedling growth (especially the root elongation), the formation and growth process of lateral roots and the seedling vigour index. The delay effect of growth process is very pronounced in the case of high concentration. |
