Allelopathic Effects of Extract Robinia pseudoacacia L. and Chenopodium album L. on Germination of Tomato (Solanum lycopersicum L.)
Allelopathy can have an important applicaiton in areas of agriculture, especially in integrated protection from weeds, by using of allelopathic crops in different ways. In this research allelopathic effects of invasive species acacia (Robinia pseudoacacia L.) and white goosefood (Chenopodium album L.) are explored on germination of tomato (Solanum lycopersicum L.). Water extracts of dry leaves of white goosefoot and acacia are prepared according tothe method : Norsworthy (2003). Experiment has been made in controlled laboratory conditions. Results of this research show that acacia and white goosefood have negative allelopathy potential and they act inhibitory on germination of tomatoes. Research of allelopathy and allelopathic relationships of weed species and agricultural cultures represents a big challenge for those people who are working in food production, and at the same time can be an instrument of ecologically sustainable agriculture.
