Field studies showed the increase of Amaranthus viridis density in an infested area by Trianthema portulacastrum more than uninfested area, while no difference in soil physicochemical characters at both areas. Bioassay was done under two different temperatures 25 and 35 degrees C with different types of T. portulacastrum leaf and stem extracts. The untreated seeds showed very small germination percent at the high temperature, while the treated seeds showed very high percentage. Different types of extracts had highly significant increase in seed germination, radicle and plumule growth of A. viridis. Treatment by T. portulacastrum extracts increased soluble protein, amylase and total phenol of A. viridis. Stimulation of all the previous parameters was higher in high temperature than in the lower. HPLC analysis for T. portulacastrum leaf and stem estimated eight phenolic compounds. The present study supports the ecological importance of allelopathy in Agriculture. 000046057 590__ $$aIV-20 000046057 650__ $$aAMARANTHUS VIRIDIS 000046057 650__ $$aALLELOPATHY 000046057 650__ $$aECOLOGY 000046057 650__ $$aGROWTH 000046057 650__ $$aSEEDS 000046057 650__ $$aGERMINATION 000046057 650__ $$aTEMPERATURE 000046057 690__ $$aTrianthema portulacastrum 000046057 691__ $$aB700 000046057 7001_ $$aAl-Sherif, E.A. 000046057 7001_ $$aGharieb, H.R. 000046057 773__ $$tAFRICAN JOURNAL OF AGRICULTURAL RESEARCH$$j6(32):6690-6697$$yAJARAF$$w42198 000046057 8564_ $$s1499134$$uhttp://worldveg.tind.io/record/46057/files/e04796.pdf 000046057 901__ $$a53873 000046057 902__ $$aAV-12 000046057 903__ $$aN 000046057 903__ $$aZ 000046057 904__ $$aM 000046057 911__ $$aIndigenous Vegetables$$bIV$$cMAIN$$dIV-20 000046057 912__ $$e2012-03-16$$kCHEN 000046057 918__ $$aEn 000046057 980__ $$aLIB
