Mixture of Growing Medium with IAA, Biochemical and Chemical Properties in Euphorbia Pulcherrima Cultivation

In the experiment there were used rooting of cuttings of poinsettia Euphorbia pulcherrima 'Prestige Early Red'. This cultivation of plants was carried out in cell trays with the use of commercial peat growing medium ‘Klasmann Steck Medium’, containing four concentrations of indole-3-acetic acid (IAA), (natural concentration and 200, 300 and 400 μg kg-1 additionally). Data indicates that the mixture of substrate with IAA had an impact on chemical compounds and enzymes activity before and after rooting of cuttings of poinsettia. These investigations revealed that higher activity of xanthine oxidase and peroxidase were observed before cultivation of poinsettia. However, different results related to phenol oxidase, urease and nitrate reductase activity were noted
