摘要：The study was focused on the impact of an extract of Ecklonia maxima on selected morphological features of yellow pine (Pinus ponderosa Dougl.ex C.Lawson), prickly spruce (Picea pungens Engelm.) Variety Glauca, thuja (Thuja occidentalis) variety Smaragd.The experiment was established in April 12, 2012 on the forest nursery in Ceranów.April 15, 2013 was introduced research agent in the form of a spraying an aqueous solution extract of Ecklonia maxima with trade name Kelpak SL.Biologically active compounds in the extract are plant hormones: auxin and cytokinin.There were studied increment in plant height, needle length of yellow pine, twigs length in prickly spruce and thuja.The measurements of increment in length of twigs and needles were made in each case on the same, specially marked parts of plants and have carried them on the 27th of each month beginning in May and ending in September.The results were evaluated statistically using the analysis of variance.Medium differentiations were verified by Tukey's test at a significance level p ≤ 0.05.The study showed that the diversity of traits features in the experiment was depended on the extract, the tree species and the measurement time.The best results after the extract using showed a pine and spruce.Seaweed preparation contributed to increment increased of trees height for in the pine and spruce and the needles length of pine and twigs of spruce.The species showing no reaction to the extract was thuja.
