Abstract

Allelochemical materials effect growth and physiology of plants in different ways.Inthis study responses of the Lactuca sativa L.on some physiological,biochemical and molcular aspects with 0.0001,0.001 mg/ml concentration of Xantothoxin in compression to control group was investigated.The evaluated aspects contain germination on dewy weights and withered weights of shoots and roots of plants,on centent of chlorophyll and fluorescent chlorophyll,the activity of enzymes like Ascorbate peroxidase,Catalase,Poly phenol oxidase and Protase,and also Electrophoresis pattern of protein and DNA in acryl amid gel.Present study showed that germination,dewy and withered weight,amount of chlorophyll,protein were reduced.As well as xantothoxin was deterrent grow root .there was no signifcant change in chlorophyll florescence.As well as activity of ascorbat peroxidase,protease,poly phenyl oxidase,catalase enzymes increased.There were remarkable changes in arrangement of electrophoresis bands of leaf protein between experimental and control group which was due to the response of Lactuca sativa.L to existence of xantothoxin. Howover,arrangement of electrophoresis bands of DNA was no signifcant change.
