Abstract
The exacerbated application of chemical control in agriculture brings several damages to the environment and man, as the herbicides are one of these routinely used tools. In this sense, the following study was carried out with the objective of evaluating by means of factorial planning 23 which factors should be considered to obtain better experimental results of the germinative inhibitory activity. Therefore the allelopathic action of the aqueous extracts of Stryphnodendron adstringens and Anemopaegma arvense, obtained at two temperatures (25ºC and 100ºC) and two types of receptors (Lactuca sativa seeds and Lycopersicum esculentum seeds). The tests were performed in duplicate with the 50% and 100% (v/v) concentrations of each extract. Therefore, the temperature of the extracting solvent, characteristic of the receiver seed and concentration of the aqueous extract of the medicinal plant, are the factors observed in this experimental design The results of the factorial planning showed that the seed factor was predominantly influencing the activity of S. astringens and A. arvense as inhibitors of germination of L. sativa and L. esculentum, respectively, therefore reinforcing that the plant-plant interaction follows an ecophysiological specificity.
