- Calendula officinalis, daminozide, essential oils, flowering, flowers, leaves, plant growth substances
- In order to study effect of plant growth retardants on Calendula officinalis, a factorial experiment was arranged based on RCB design with two factors: four levels of CCC and four levels of daminozide in 3 replications. Plant height, number of flowers per plant, number of leaves per plant, flower dry weight, flower fresh weight, time of flowering and amount of essential oils of dried flower, were measured. Results showed that effect of cycocel and daminozide were significant on amount of essential oils per dried flower and plant height (p≤0.01) and interaction effects of cycocel + daminozide were significant on plant height, number of flowers per plant, number of leaves per plant, flower dry weight and amount of essential oils per 100 g dried flower. The lowest plant height, the highest number of flowers per plant, the highest number of leaves and the highest amount of essential oils per dried flower, were observed.
