      The hairy roots of A. conyzoides were established with Agrobacterium rhizogenes for increasing the production of chromenes. The main compounds as β-farnesene, precocene I, and β-caryophyllene were estimated and enhanced in production in the presence of light conditions and also on the age of cultures. Precocene I, β-farnesene, precocene II, and β-caryophyllene are the main compounds of the volatile oils from the parent plant roots and, along with germacrene D, are also located in the parent plant's aerial parts. Qualitative and quantitative differences were found between the volatile oils from the roots of the parent plant and those from the hairy roots (Abdelkader and Lockwood 2011).
