Abstract
Weed is an important problem in crop production. Allelophaty is a natural mechanism in which plant effect to germination and growth of other plants. Therefore; the objectives of this study were to determine the chemical composition of Sweet leaf (Sauropus androgynus (Linn.) Merr.) Dill (Anethum graveolens Linn.) and Yanang (Tiliacora triandra Diels.) and study the effects of all three plants extracts on seed germination and growth of Mimosa invisa Mart. Ex Colla and Leucaena leucocephala. All three plants were extracted by 70% ethanol. The solvent was removed by rotary evaporator and then by freeze dryer. The chemical composition of extracts were identified by gas chromatography-mass spectrometer. The most major chemical composition of S. androgynus, A. graveolens and T. triandra were Ethyl linolenate (16.14%) Phytol isomer (7.73%) and Phytol (24.22%), respectively. The results showed that the concentration of S. androgynous extract at 30 mg/ml inhibited the seed germination of M. invisa for 100% (P < 0.05) and A. graveolens extract at concentration of 30 mg/ml inhibited the seed germination of L. leucocephala for 73% (P < 0.05). Moreover, the three plants had the highest effect on the seedling growth of M. invisa for 100% (P < 0.05). The extract from A. graveolens at 30 mg/ml concentration had the highest effect on the shoot and root growth of L. leucocephala for 92% and 100%, respectively (P < 0.05). Therefore; it is concluded that the extracts of the three plants were inhibited the seed germination and the growth of M. invisa and L. leucocephala.
