Investigation of the allelopathic effects of lyophized ethanol extract of Xanthoparmelia somloensis (Gyelnik) Hale lichen on tomato plant

All organisms in nature interact and compete with each other. Various groups of such as algae, lichens, crops weeds have been found allelopathic interaction it is known that lichens many potent secondary metabolites. The aim this study was to determine the effects lyophilized ethanolic extract Xanthoparmelia somloensis (Gyelnik) Hale lichen (XS) on tomato (Lycopersicum esculentum L.) germination early development stage. Obtained extracts XS at concentrations 50 ppm (XS-50), 100 (XS-100), 200 (XS-200) 400 (XS-400) were applied seeds seedlings. In order caused by extracts, rate seedling growth parameters (vigor index, length, fresh weight, relative water content pigment contents) analyzed. According obtained data, there significant decreases vigor index values depending increase concentration. Similar also observed root shoot length contents. However, results lowest application (XS-50) similar control except carotenoid content. data from exhibited has potential be used for agricultural purposes.
