Biochemical composition of some aromatic and medicinal plants after cultivation on the multi circle hydroponic installations

Abstract

Multi circle hydroponic construction for vegetable and greens cultivation are wide spread and supported of leader investors all over the world because their economic position and ecologic status. Cultivation of aromatic and medicinal plants at multi circle hydroponic construction is usually supplemented the study biochemical composition above parts of plants after cultivation. The goal of study is: analysis biochemical composition above parts of some aromatic and medicinal plants after cultivation at multi circle hydroponic construction. Objects of study - above parts of aromatic and medicinal plants from Lamiaceae-family: Monarda fistulosa L., Nepeta cataria L. , Mentha piperita L., Melissa officinalis L.; from Hypericaceae-family - Hypericum perforatum L. and from Apiaceae-family: Coriandrum sativum L., Anethum graveolens L., Apium graveolens L. Plants were cultivated at the 5 circle hydroponic construction with artificial lighting and automatic nutrition. Seeds of Apiaceae-family were treated with water solutions of natural immunomodulators: linarozide and moldstim. Analytic methods included determination: the dry matter content, antioxidants content and polyphenols content. Statistical methods: one-factorial and two-factorial dispersion analysis (Microsoft Excel, 2010). The first experiment of the cultivation aromatic and medicinal plants at 5 th circle hydroponic installation was successful. The content of dry matter, vitamin C and chlorophylls does not change depends on plants location, but the content sum of polyphenols was significantly higher on the above part of Monarda fistulosa plants from the 4 th circle. The highest content of polyphenols was observed on the above part of Hypericum perforatum L., the smallest content - on the above part of Mentha piperita L. Treatment seeds with natural immunomodulators increased the content of dry matter, antioxidants and polyphenols on the above part of plants from Apiaceae-family. It influenced at the increasing of seed germination, height of plants and weight of above parts. But accumulation of antioxidants and polyphenols on the above parts of Apiaceae-plants was specific for every species.
