Abstract

Some plant species inhibit germination and growth of other plant species by secretion of specific chemical substances. In order to survey the allelopathic effect of five Amaranthus species (which are among the most prominent weed species in Golestan province) residues on Soybean seeds germination, a factorial complete random design experiment was conducted. The extract of Amaranthus species (allelopath) organs were chosen as main factor, water extract with different concentrations and seed germination as factorial and subsidiary factors. The results were analyzed using Mstatc software and the means for each characteristic were compared with Duncan's Multiple Range Test (P>0.01). Water extract of all Amaranthus species surveyed in this experiment had negative effect on Soybean var. DPX seeds germination. In addition, there was a slight difference in the allelopathic effect of surveyed species (effect of the type of allelopath). A. viridis with 62% had the highest and A. blitoides with 52% the lowest effect. There was not a significant difference between A. viridis, A. albus and A. hybridus. Similar results were also obtained between A. retroflexus and A. blitoides. The effect of different water extract concentrations of these species on Soybean var. DPX seeds germination was significant; allelopathic effect increased with the increase of concentration. From the survey of concentration and allelopath type interaction it could be concluded that 100% concentration of A. viridis had the highest allelopathic effect (88% germination decrease) in contrast with A. blitoides 25% concentration which had the lowest effect (28% decrease). To sum up, total plant organ water extract of these Amaranthus species have allelopathic properties on Soybean seeds germination. That is why, it is recommended that during Soybean cultivation as a secondary crop in a field containing weed residues of these species, either weed residues be evacuated from the field or considering the mentioned results, a higher amount of seeds be used, in this way a considerable decline in crop growth could be prevented.
