Metabolic changes of black locust (Robinia pseudoacacia L.) caused by allelochemicals of competitive woody plants.
Black locust (Robinia pseudoacacia L.), despite of many positive features, as an invasive species represents significant environmental risk. For this reason, we tested possibilities of its bioregulation using allelochemicals of competitive woody plants black cherry (Prunus serotina Ehrh.) and common hackberry (Celtis occidentalis L.). For this reason parameters of N metabolism (ureids, proteins), stress level (hydrogen peroxide) and photosynthetic pigments (chlorophylls, carotenoids) were analyzed. Allelochemicals of common hackberry are more effective for bioregulation of black locust, than allelochemicals of black cherry.
