“…Similar findings had been described by Oh and Kim [7], where the administration of GA 3 at a concentration of 100 mg/L increased petiole elongation and plant height of Cyclamen persicum 'Metis Scarlet Red'. Alshakhaly and Qrunfleh [9] reported that foliar applications of GA 3 with concentrations ranging from 25 to 100 mg/L on Cyclamen persicum specie effectively increased petiole elongation and flower development. Consequently, increased active GAs promoted petiole elongation and the positive effect of total contents of active GAs was greater under low rather than high irradiance [8].…”

“…Gibberellic acid (GA 3 ) is a natural plant regulator with multiple applications in agriculture and horticulture industry due to its positive impact on plant growth and development. Its positive effects have been demonstrated in multiple crops and ornamental plants by exhibiting enhanced seed germination [5,6], shortening the juvenile phase, leaf expansion and development, stem elongation [7,8], early flowering [9][10][11][12][13] and fruit development; their role in the promotion of flowering in plants was reported in several studies, including Arabidopsis thaliana (thale cress) [14], Brunonia australis R.Br. (blue pincushion or native cornflower) [15], Henckelia humboldtianus (Humboldt's Stone Flower) [16], and Iris nigricans Dinsm.…”

Cyclamen species (swinebread spp.) are perennial herbaceous plants which belong to the Primulaceae family, widely used as medicinal or ornamental plants. Currently, gibberellic acid (GA3), an environmentally friendly bioregulator is widely used to enhance the productivity and phenotypic characteristics of multiple ornamental crops. A dual experiment was conducted to evaluate the influence of gibberellic acid (50, 100 or 150 mg/L), on germination earliness of seeds, along with growth and ornamental quality of selected Cyclamen species. Additionally, a greenhouse experiment with long and short sunlight photoperiod was conducted to evaluate its importance in the development of Cyclamen plants. Our results indicated that under short sunlight exposure, seeds germinated earlier than those kept in long sunlight photoperiod. Plants treated with foliar applications of GA3 exhibited higher plant height, leaf area, number of leaves, root length and tuber development. Significant differences were found in germination percentage (GP), mean germination time (MGT) and seedling vigor index (SVI), within different GA3 supplementation and greenhouse sunlight intensity (short and long days). In conclusion, our study suggests that seedling vigor and ornamental quality can be increased by GA3 application, an economic strategy for enhancing germination and growth of selected Cyclamen species.

“…They also regulate various developmental processes such as leaf expansion, fruit development, and the transition from vegetative to reproductive growth [28]. The effects of gibberellic acid (GA3) have been proven and documented in numerous crops and ornamental plants, as well as cyclamens, as they have the remarkable ability to significantly improve stem elongation and early flowering [29,30]. Gibberellins are also involved in regulating plant responses to environmental cues such as light and temperature [30].…”

In Eastern Europe, the traditional marketing of cyclamen is in the period from the middle of February to the middle of March. The poor light of winter months and the higher number of plants (because of the reduction in heating costs) often result in elongated plants. To avoid this, it is recommended to use plant growth retardants. At the same time, another problem is that flowers do not rise from the level of rosette due to the unfavorable cultivation conditions. This can be solved with growth stimulants. In the experiment, we tested the effect of growth regulators on the growth of a frequently used variety of cyclamen. We used daminozide and paclobutrazol plant growth retardants for height control and gibberellic acid (GA) and benzyladenine (BAP) as growth promoters for increasing the number of flowers and the length of stems. The results show that daminozide and paclobutrazol are both effective for height control in cyclamen production.

This study was carried out to evaluate the effects of different plant growth regulators on the ornamental sunflower plant. The seedlings belonging to Helianthus annuus L. cv. Sunsantion F1 were planted in plastic pots (2 L) containing peat: perlite (1:1, v/v) medium at four true leaf stage. Spray treatments of aminoethoxyvinil glycine (AVG; 250 and 500 ppm), Promalin (5 and 10 ppm), Thidiazuron (TDZ; 5-10 µM), Ethephon (100 ppm) were applied to seedlings 20 days after transfer to the pots, and treatments were repeated 10 days after the first application. Flower life (days), flower diameter (cm), stem diameter (cm) and plant height (cm) were determined. According to statistical analysis, AVG at 250 ppm significantly increased the flower life from 9.17 d in control plants to 11.08 d whereas there were no significant effects on flower diameter and plant height. Both concentrations of Promalin and TDZ increased stem diameter significantly. However, TDZ increased the flower life from 9.17 d (control plants) to 10.36 at 10 µM and 10.33 at 5 µM TDZ. Ethephon application prevented flower bud opening and caused the leaves to be yellowing. These results may suggest AVG and TDZ pre-treatments increase the quality and shelf-life of the potted sunflower plant.
