The growth retardant ALAR was applied at different rates to study its effects on some anatomical and chemical changes in concentrations stems cutting growth of local cultivar of Chrysanthemum morifolium in terms of leaf area, leaf thickness and chlorophyll content, in addition to measure the ability of cut stems to resist drought conditions. The results showed that treated leaves were normal in shape but with reduction in the leaves area associated with darker green colour (high amount of chlorophyll content) with respect to the concentrations applied. Treated plants showed some tolerance to dry conditions.
