The influence of copper on some physiological and morphological indicators of Impatiens Balsamina L.

Abstract

This paper presents the results of a study regarding the influence of treatment with copper in different concentrations (10mg/L, 20mg/L, 40mg/L, 60mg/L, 100mg/L and 150mg/L) on some physiological and morphological indicators of Impatiens balsamina species. The following indicators were analyzed: the percentage of germinated seeds, the mean time of germination, the length of the root and of the hypocotyl, the tolerance index. The following effects were found: the pronounced reduction of the germination percentage and the increase of the germination mean time in high concentration; the delay of the growth in length of the root and the hypocotyl; the decrease of the tolerance index. The root was more affected than the hypocotyl.
