Marjoram plants grown under different levels of salinity [0.0, 10, 25 and 40% of sea water]. For this reason two pot experiments were conducted during 2001 and 2002 seasons. The obtained results clearly confirmed the absolute superiority of foliar application of 10 1..1 M putrescine treatment, which significantly increased plant height, number of branches/plant, herb fresh and dry weight /plant, essential oil percentage [ml/100 g F.W] and oil yield [ml/plant] under norm~l or saline conditions up to 25% sea water. The data also revealed that tolerance, which was much pronounced as a result of foliar application of 10 llM treatment, was more negative osmotic potentials (Osmotic Adjustment) through the accumolation of much more quantities of inorganic osmotica,  aSummary in Arabic. 0aMedicinal plants. 0aAromatic plantsxFertilizers. 0aPutrescine. 3amarjoram.1 aEI-Ghadban, E.A.E.0 tMansoura University Journal of Agricultural Sciences. g2003.v.28(4)x1110-03467nnaswu18219740uhttp://nile.enal.sci.eg/EALE/2003/MUJAS/2803/4/2987.pdfzFull Text Article.  a1  cAR2lcc  c56187d56187
