Abstract:
This study focuses on the power of allelophatic aqueous leaf extract of Pituranthos
chloranthus l, harvested in the region Ghardaia northern Sahara on the germination of barley grains
hordeum vulgare l .Poaceae.
This study allowed us to see that the leaf and root extracts of this plant have agermination
inhibitor, the aqueous extract of leaf it is us66,67%, 65.00 % , 56,67%, 50.00%, 50,00% , 46,67% ,
41,67%, 36,67% , 26,67%, at,100%, 90% , 80%, 70%, 60%, 50%, 40%, 30%, 20%,
10%,respectively seed of hordeum vulgare l treated with aqueous root extract diluted to100%, 90%,
80%, 70%, 60%, 50%, 40% , 30%, 20%, 10%,it is at 91,67%, 71,67%,66,67%, 65,00%, 56,67%,
50.00%, ,46,67%, 46,67%, 43,33%, 31,67%,respectively.
Also it is reported delays germination and growth of grain test treated compared to control
batch plant grains
