Investigation of hetrotoxicity potential of aqueous extract of various organs from medicinal plant of Malva sylvestrisa )L.( on Cichorium intybus )L.( and Echinochloa crus-galli )L.(

The purpose of this experiment, evaluating hetrotoxicity potential of aqueous extract of various organs of medicinal plant of Malva sylvestrisa L. on morphological, physiological characteristics and biochemical of total phenols of Cichorium intybus L. and Echinochloa crus-galli L. under hydroponic culture as two separated experiments in completely randomized design in botanical laboratory of Gonbad Kavous University in 2017. For experiment, aerial parts of M. sylvestrisa were collected in flowering stage from Ramian fields and then various organs such as stem, leaf and flower was divided and finally were powdered. At the end, 5% suspension from each organ and a mixture of organs were supplied and added to hydroponic culture containing 7 days old seedlings of C. intybus and E. crus-galli. The results showed different responses C. intybus and E. crus-galli to aqueous extract of various organs of M. sylvestrisa. So that studied treatments had a different additive effect on morphological characteristics, photosynthesis pigments and total phenols.  The highest additive effect on root length, plant height, leaf area, dry weight per plant, content of chlorophyll b and total chlorophyll were obtained for extract of flower organ. In case of chlorophyll a, carotenoids and total phenols content, the most of this amount were found for extract of leaf, leaf and mixture of organs respectively. Although had no significant difference with some other treatments. In case of C. intybus, aqueous extract of M. sylvestrisa leaf only had a significant inhibition effect on leaf area, dry weight per plant, content of chlorophyll a, total
