Abstract

An experiment to study the effect of mixture of phenolic substances on germination of Euphorbia prunifolia weed seeds was carried out at the Laboratory of Department of Agronomy Faculty of Agricultnre Andalas University Padang during the period of May to June 1999. Treatments were concentrati on of mixture of six phenolic substances (coumaric acid, anisic acid, isoverulic acid, salisilic acid,vanilin, and salisil aldehide) i.e. 0, 200 ppm, 400 ppm, 800 ppm, 1200 ppm,and 1600 ppm. Trearments were alranged in Complete Randomized Design with three replications. Data were collected on germination percentage, index value, length of radicle and plumule; and final data were analyzed statistically. Result indicated that mixture of phenolic substances at the concenffation up to 1200 ppm suppessed the germination, while at the concentration of 1600 ppm inhibited the germination of Euphorbin prunifutia weed seeds.
