Abstract :
Cyclamen is one of the most exportable herbs and also used in the pharmaceutical industry. Hence, increasing the number of flowers, the durability and shelf-life of the cut flowers is important. Alcohol has positive effect on these properties in low concentration. Therefore, the aim of this study was to investigate the effect of alcoholic treatments on the development of reproductive meristem, the change in the number of flowering branches and the possibility of delaying aging in the cut flowers of the cyclamen. Therefore, pots containing vegetative parts of the cyclamen plants that have not yet entered the stage of reproduction were obtained form a greenhouse for the development of cyclamen in Tehran. Then, the control samples were sprayed three times a week to 10 cc of distilled water , and the treated samples were subjected to the same treatment under the influence of ethanol and alcoholic treatments. Methanol at concentrations of 1.5% , 3% and 6% . In this research, flower buds were harvested at three stages, and by conventional methods of cell-histology , the stages of development of reproductive meristem, formation of buds and flowers were studied. The results of examination of the same age and size buds in the control and control samples showed that alcohol accelerates the developmental stages of the various parts of the flower components.
