Abstract
Abstract The purpose of this paper is to study the dynamic of pigments level in sunflower sprouts after zinc compounds supplementing in growth. Was evaluated as the content of total chlorophylls, chlorophylls a, chlorophylls b, carotenes and xanthophylls. Seedlings were obtained by germinating of sunflowers greens in the presence of Zn. For germination were used textile germination beds. There were six groups: Group 1 - distilled water;Group 2 - potable water; Group 3 - ZnSO 4 -50 ppm Zn;Group 4 - ZnSO 4 -100 ppm Zn;Group 5 - (CH 3 COO) 2 Zn -50 ppmZn;Group 6 - (CH 3 COO) 2 Zn- 100 ppm Zn. We observed the increasing of chlorophyls a,b and total for the groups treated with zinc sulfat, comparative with control groups and the negative influence of zinc acetate solution on pigments syntesis, at 50 ppm dose as well as at 100 ppm dose. Application of zinc sulphate or zinc acetate solution had a negative influence on the carotenes and xanthophylls content in sunflower sprouts.
