Allelopathic effects of weedsl on germination and initial growth
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 3
Abstract
Recently weed scientist are more interested in weed management by allelopathy . In order to determination of Allelophatic effects of Carthamus oxyacantha and Chenopodium mural extract on the Phasaeolous vulgaris grains germination, during 2011-2012, one experiment in the completely randomized blocks design with 4 repetition carried out in the laboratory of agricultural collage of Azad university in the shoushtar city. The test treatments were included different rates of Various parts extract of Carthamus oxyacantha and Chenopodium mural consist of organ, root, and combining both of them, as well as, densities 0, 25, 50, 75 and 100 percent. Experimental units were Petri dishes in depth and diameter 3 and 9 Cm, respectively. The germination and its rate, rootlet length, dry weight of Phasaeolous vulgaris plat let evaluated according to ISTA (International seed Testing Association). The results indicated that extract of Carthamus oxyacantha and Chenopodium mural to have significant and various allelophatic effects upon Phasaeolous vulgaris grains germination. But germination characteristic, length and dry weight of radical (rootlet) were decreased for the reason build up extract density. A Phasaeolous vulgaris plan, showed that it has more sensitivity to Carthamus oxyacantha extract, particularly that, root. The most allelophatic effects is related to extract of Carthamus oxyacantha root and Chenopodium mural aerial organs.
