بررسی پتانسیل آللوپاتیک عصاره اندامهای هوایی ذرت بر جوانهزنی و رشد گیاهچه علف هرز تاج خروس

Water potential of different concentrations (0, 20, 40) aqueous extracts on seed germination and root growth of maize shoots or red root pigweed (Amaranthus retroflexusl) in vitro in a factorial randomized complete block design with three replications was. The results showed that the germination rate, germination, mean germination, root and shoot ratio, shoot length, root length, root dry weight, shoot dry weight, root mean concentration of C in all cases, ie disagree with. With increasing concentration and uniformity of germination, root and shoot decreased the extract concentration ( 0 ) increased and then decreased with the concentration of 20 and 40 respectively. Amaranth extract concentration was 40, the lowest percentage of germination is generally the most sensitive species in the aqueous extract of red root pigweed is corn.
