تأثير مستخلصات بعض الأعشاب على إنبات بعض الأعشاب الضارة التي تنمو في منطقة الوادي

Abstract

The purpose of this study is to search for natural materials of plant origin that can be used as weedkillers, so we selected (cynqnchum murale l,cyperus l.chenopodium rotundus l,sonshusasper l)plants and studied the extent of their effect on the germination of certain weeds in the area of Oued Souf. And represented by two plants (CY.S) at the germination stage. Aqueous extracts were prepared from CY.CH.C.S plants and distilled water was used as a control. The effect of extracts was tested by soaking and sprinkling on seed germination (CY.S) The results obtained showed that the aqueous extracts have a negative effect on germination.
