There are many experiments of zinc effect on wheat final leaf or wheat germination percent. Soil constraints affect potential grain yield of wheat. Among those constraints, acidic soils are especially important due to their combined effect on zinc.The originality of the present study consists of the evaluation of the response of wheat shoots (not final leaf) obtained by grain germination consecutive to zinc feeding, as acetate or sulphate on textile support(not soil).The content quantification of chlorophyll, carotenes and xanthophylls of wheat shoots obtained in the presence of zinc has demonstrated the requirements and benefits of that at 50 ppm doses. Zinc effects al 100 ppm have not so efficiently raised the content of these pigments.
Therefore, zinc sulphate proved to be more stimulant for pigments' synthesis, in comparison with zinc acetate.
