Abstract

The biosynthesis and the accumulation of the chemical composites that have allelopathy characteristics in Salvia officinalis L. (Lamiaceae) are resulting from the secondary plant metabolism. The present work had as objective to analyze the allelopathic effects of aqueous extracts of fresh leaves of Sálvia collected during the seasons, obtained by decoction, static infusion and grinding, on the germination and development of seedlings of lettuce (Lactuca sativa L.). The experiment had 20 treatments (concentrations 0; 7.5; 15; 22.5 and 30%). The results had been submitted to the Tukey test, to the level at 5% probability. The appraised variables, germination percentage, the germination speed index (GSI), the growth of shoot and roots and abnormality formation of seedlings did not present a pattern of allelopathy in the different seasons, indicating a possible alteration in the plant metabolism in function of the seasonal variation in the plant ambient.
