The Effect of Water Stress on Yield Components and Essential Oil ofPelargonium graveolensL.

Abstract
The influence of water stress created by increasing the interval between the last irrigation and harvest, was examined with geranium (Pelargonium graveolens L.) plants. On some of the morphological characters and yield components, water stress had a negative and on others a positive influence. The green yield and essential oil yield decrease as the intervals increase, as does the ratio between citronellol and geraniol in the essential oil.
