ALLELOPATHY EFFECT OF A CHLOROFORMIC FRACTION OF <I>Lagascea mollis Cav</I>.(ASTERACEAE) ON THE GERMINATION AND ROOT GROWTH OF <I>Oryza sativa</I> L.

In this work, the study of the allelopathic activity of terpenic lactones on chloroformic fractions of Lagascea mollis Cav (Asteraceae) is reported. To this effect it is determined the percentage of germinated seeds and the radicular length of rice seeds (Oryza sativa L.). The observed bioactivity i...
