Abstract
3 Abstract: This investigation was carried out at the greenhouse of National Research Centre, Egypt to study the response of Geranium (Pelargonium graveolens) to different levels of soil moisture and zinc treatments. The results indicated that, plant growth i.e. plant height (cm), branches number and shoot fresh weight decreased with irrigation plants after depletion of more or less 50% of field capacity. Drought increase essential oil % and decreased oil yield. Zinc 1000 ppm proved to be affective in increasing the yield of Pelargonium graveolens essential oil. The volatile profile of odorous parts of the plant was analyzed by GC/MS. The major compounds in essential oils were oxygenated monoterpenes with geraniol (54, 12%) at 1000 ppm of zinc. Subjecting Pelargonium graveolens to 30 % depletion of field capacity increased the constituent geraniol with (34, 73%),while under water stress 70% depletion of field capacity germacrone was increased.
