Abstract

In order to study germination characteristics and early growth of Portulaca oleracea, under different treatment of Walnut (W) and Elderberry (E), Two separate experiments were carried out in a factorial arrangement a Completely randomized with three replications over a farm season (2017). Treatments included Walnut and Elderberry hydro-alcoholic extract in concentrations of 0, 20, 60 and 100%. Results of the analysis of the variance of the laboratory and the greenhouse showed that the Walnut and Elderberry hydro-alcoholic extract had a significant effect on all the characteristics, So that the highest inhibitory effect was observed in 100% Walnut and 100% Elderberry. comparison of the average data from the experimental section showed that with increasing the the Walnut and Elderberry hydro-alcoholic extract in the experimental section germination percentage, germination speed, root length, stem length, fresh and dry weights, and indices of Portulaca oleracea seeds vigor index were reduced compared to witnesses. comparison of the average data from the greenhouse segment showed that with increasing the concentration of the extract stem length, Stem dry weight, Root dry weight, Number of leaves plant, Number of roots in the plant, photosynthesis pigments such as chlorophyll a, b and carotenoids increased significantly and proline increased. Also, the growth of the  roots of the plant has a significant decrease in its meaning. which resulted in a decrease in the dry weight and dry weight of the Portulaca oleracea. according to the results obtained in this study Walnut and Elderberry hydro-alcoholic extract at a concentration of 100% concentration can be used to control Portulaca oleracea.
