Abstract:

The aim of this study is to give an overview about content and constituents of oils found in umbelliferous crops and the conditions influencing oil content in those crops. The large family Umbelliferae is rich in essential oils. Oils play the phytosanitary role by preventing parasites and diseases from developing or by acting like selective weed-killers in order to keep the ground clean around the plant. Factors influencing oil content in umbelliferous crops are: the latitude of cultivation, the climatic and weather conditions, diurnal and annual rhythm, salinity, fertilization, irrigation, growth retardants, plant development, the plant part used, variety, harvesting and storage.
