Effects of Plagiomnium undulatum (Bryophyta) Extracts on Seedling Growth of Sinapis arvensis

In this study, allelopathic effects of Plagiomnium undulatum (Hedw.) T.J.Kop., a bryophyte species, on Sinapis arvensis L. (wild mustard) seedlings from common weeds were investigated. Three different solvents (distilled water, ethyl alcohol and ethyl acetate) were used to obtain extracts from P. undulatum, the effect of different concentrations (0, 25 and 50 mg.mL-1) of these extracs on some physiological and biochemical parameters in seedling growth of S. arvensis were determined and evaluated according to control groups. Photosynthetic pigment contents, total protein amount, proline concentration and antioxidant enzyme activity results showed that P. undulatum extract has allelopathic effects on wild mustard seedling growth.
