Evaluation of allelopathic effect of aqueous extracts in mallow on seed germination of breed wheat hamoon cultivar

To investigate the allelopathic effect of aqueous extract of Malva sylvestris weed on the germination characteristics of Triticum aestivum (hamoon cultivar), an experiment was conducted in 2019 in the Biotechnology Research Institute, University of Zabol. The experiment was conducted in a completely randomized design with three replications. The aqueous extracts concentrations of Mallow included 0, 25, 50, 75, and 100 ml/L. The experimental results show that the aqueous extract of Malva sylvestris had a significant effect on radicle length, hypocotyl length, germination percentage, chlorophyll b, and phenol. The results indicated that different concentrations of aqueous extract of Malva sylvestris have a different trend on the measured traits. Although with increasing the concentration of Malva sylvestris extract, the percentage of germination, radicle, and hypocotyl length has decreased, the synthesis of chlorophyll and phenol in wheat treated with 50 ml of aqueous extract of Malva sylvestris has reached its maximum. At a concentration of 100 ml of aqueous extract of cottage cheese, root length and germination percentage decreased by 65% and 85%, respectively, compared to the control. The results of this study showed that aqueous extract of cheese had a negative effect on the growth characteristics of wheat.
