Abstract
The effect of different dates and periods of light treatment is studied on some important cut flower plants, namely callistephus chinesis, nees and antirrhinum inajus l., Due to their importance as popular cut flowers for home use. Their normal flowering supplies the demands during spring season, so any elongation of earliness of flowering is considered of economic benefits. The obtained results show that the great importance especially for export purposes-during the months of December till March of European markets, is quite evident.
