Phytotoxic Potential of Methanolic Extract of Cardia obaliqua

Abstract

Cardia obaliqua is used traditionally for the treatment of various ailments in Pakistan and in some other countries of the world. In the present study methanolic extract of various fractions of Cardia obaliqua are used for the screening of phytotoxic potential. Two concentrations of crude methnolic extract i.e. 1000 µg ml -1 and 100 µg ml -1 was used in the assay. The Cardia obaliqua methanolic extract (COME) showed significant inhibition both in hypocotyls/shoot and radicals/roots growth i.e. Cardia obaliqua showed maximum inhibition for the growth of Aveenasativa and Triticumaestivum. These results provide evidence that Cardia obaliqua might be used affectively as bio herbicide for weeds control.
