This study was conducted to examine the
allelopathic potential of aqueous extracts
(A.E.) of two wild plants Bassia muricata(B.
muricata) and Chenopodium mural (Ch. Mural)
at Different concentration (1, 5, 10, 15,20,
and 25% w/v) in addition to 0% (tap water) as
control ,on seed germination, seedling growth
and chlorophyll ,protein and sugar content of
Phaseolus vulgaris .L. (Kidney bean). Gas
chromatography mass spectrum (GC.MS)
analysis revealed the presence of 33
bioactive compounds for Ch. mural extracts
and 31 compounds for B. muricate and this
analysis showed the presence of many
compounds as fatty acid, aliphatic
hydrocarbon, polyphenol and sterols. The
obtained results indicated that shoot aqueous
extract (S.A.E) of B. muricata and Ch. mural
at (1% to 15%); (1% and 5%), respectively as
seed soaking for 24 hours stimulated
germination percentage and support all tested
morphological and physiological parameter of
the Phaseolus vulgaris plants, while the
reduction was observed at (20 and 25% w/v)
in B. muricata and the completely inhibition of
Ch. Mural extract was started from 10% as
compared with the untreated control plant.
The stimulating effect for both wild plants may
be related to the presence of the polyphenolic
compounds and steroidal hormones according
to the concentration. The phytotoxic activity
(completely inhibition) of Ch. mural could be
related to the presence of coumarin and its
derivatives (3-(3,4-dimethoxyphenyl)-7-
methyl-4-phenylcoumarin).
