One way to achieve this is by using plant growth regulators as a tool for plant growth management. In a greenhouse with a mist irrigation system, a study was conducted on dwarf schefflera, an ornamental foliage plant, which was exposed to foliar application of gibberellic acid and benzyladenine hormones. The hormones were sprayed on dwarf schefflera leaves at 0, 100, and 200 mg/l concentrations, at 15-day intervals in three stages. The experiment was conducted as a factorial based on a completely randomized design, with four replicates. The combination of gibberellic acid and benzyladenine at 200 mg/l concentration had a significant effect on leaf number, leaf area, and plant height. The treatment also resulted in the highest content of photosynthetic pigments. Furthermore, the highest soluble carbohydrate to reducing sugars ratio was observed in treatments of 100 and 200 mg/l benzyladenine, and 200 mg/l gibberellic acid + benzyladenine. Stepwise regression analysis showed that root volume was the first variable to enter the model, explaining 44% of variations. The next variable was root fresh weight, and the two-variable model explained 63% of variations in leaf number. The greatest positive effect on leaf number was related to root fresh weight (0.43), which had a positive correlation with leaf number (0.47). The results showed that 200 mg/l concentration of gibberellic acid and benzyladenine significantly improved morphological growth, chlorophyll and carotenoid synthesis, and reducing sugar and soluble carbohydrate contents in dwarf schefflera.

In this study, the physical, mechanical, antioxidant, and antimicrobial properties of starch/zinc oxide nanoparticles (ZnO NPs) composite containing various concentrations of Ferula gummosa Boiss essential oil (0.5, 1 and 1.5%) were investigated. The addition of ZnO NPs improved the thickness, and the mechanical and microbial properties, and on the other hand, reduced the water vapor permeability of the starch active film. The addition of Ferula gummosa Boiss essential oil to starch nanocomposite decreased the water vapor permeability from 6.25 to 5.63 g mm-2 d-1 kPa-1 , but this decrease was significant only in the concentration of 1.5% of essential oils (p<0.05). The addition of essential oil to starch nanocomposite caused a decrease in Tensile Strength (TS) value and an increase in Elongation at Break (EB) values was obtained by adding 1.5% of Ferula gummosa Boiss essential oil to starch. The results of the antimicrobial activity of the nanocomposite showed that the pure starch film did not show any lack of growth zone. The addition of ZnO NPs to the starch matrix caused antimicrobial activity on both studied bacteria (Staphylococcus aureus, Escherichia coli). The highest antimicrobial activity was observed in the starch/ ZnO NPs film containing 1.5% essential oil with an inhibition zone of 340 mm 2 on Staphylococcus aureus. Antioxidant activity increased significantly with increasing concentration of Ferula gummosa Boiss essential oil (P<0.05). The film containing 1.5% essential oil had the highest (50.5%) antioxidant activity. In this study, the effect of starch/ ZnO NPs composite containing Ferula gummosa Boiss essential oil was also investigated in order to increase the shelf life of rainbow salmon fillets. Microbial load, lactic acid bacteria and psychrophilic bacteria of salmon fillets were reduced by coating. Coating also improved the chemical 2 characteristics of fish fillet. In general, the starch nanocomposite containing ZnO NPs and Ferula gummosa Boiss essential oil has the ability to be used in the aquatic packaging industry.

In some cases, it is necessary to treat some non-growing branches with some growth regulators to produce enough leaves and lateral shoots. The most common treatments are topping the branch and gibberellic acid application to produce more foliage on the plant. This research was conducted to study the influence of topping and application of gibberellic acid on vegetative and reproductive growth of African marigold as a bedding plant. In this study, topping as the first factor at three levels (0, 45, and 90 days before transplanting) and gibberellic acid as the second factor at four levels (0, 100, 200, and 300 mg L-1) were applied in a pot experiment outdoor under a factorial experiment with a completely randomized design, 4 replications in each treatment (4 pots in each replication). The seeds were planted in late summer. Then, approximately 7 cm long seedlings with six leaflets were transferred to pots. Plants were treated with gibberellic acid and topping 15 to 20 days after transplanting. Foliar spraying was carried out at three stages with 10 days' intervals. Distilled water was sprayed on control plants. Results showed that using of gibberellic acid combined with a topping treatment increased the amount of chlorophyll index, plant height, length, and lateral roots volume. The number of opened flowers, bud and stem diameter had the highest performance at 120 days after spraying with 100 mg L-1 gibberellic acid. Therefore, topping combined with gibberellic acid at the concentration of 100 mg L-1 increased flowering and most other characteristics studied.

As soon as Nitric Oxide (NO) known as a new biological agent in plants and animals, biological branches of sciences like medicine, biochemistry, physiology and genetics have paid special attention to it. NO is a very reactive gas shape free radical which has attracted much attention during recent years. This compound is produced by the plant and it has increased the shelf life of some fruits, vegetables and cut flowers in low concentrations. NO is mostly synthesized from enzymatic and non-enzymatic pathways whose enzymatic biosynthesis pathway is done by reductase nitrate biosynthesis pathway through the cytosol, also it is known as an important and very reactive signaling molecule with short life which is produced by a group of enzymes known as synthesize NO which transforms Larginine to L-citrulline and NO. It has been revealed that plants use NO as a growth regulator which regulates and modifies antimicrobial defensive responses. Recently, it has been approved that this material plays a vital role in regulating the normal physiological activities of plants such as pores closing, aging, increasing the vase life of cut flowers after harvesting, respiration and photosynthesis, antioxidant enzymes activities and growth.

Among the most commonly used branching-inducers are gibberellic acid (GA3) and N 6-benzyladenine (BA) which are synthetic cytokinins that have been shown to increase shoot number in some plant species. The aim of this research was studying the effects of synthetic branching agents on a foliage plant. The effects of GA3 and BA on Ficus benjamina plant was evaluated under greenhouse condition. Plants were treated with foliar application of GA3 and BA at 0, 100 and 200 mg L-1. The plants that were treated with GA3 and BA at 200 mg L-1 showed the highest number of leaves and plant height. Foliar application of 200 mg L-1 GA3 + 200 mg L-1 BA increased photosynthetic pigments. The highest rate of soluble carbohydrates and reducing sugars were belonged to 200 mg L-1 GA3 and 100 mg L-1 GA3 + 200 mg L-1 BA, respectively. Results indicated that application of 200 mg l-1 of GA3 + BA significantly promoted morphological growth, chlorophyll and carotenoid content, reduced sugars and soluble carbohydrates in F. benjamina.

In some cases, it is necessary to treat some non-growing branches with some growth regulators to produce enough leaves and lateral shoots. The most common treatments are topping the branch and gibberellic acid application to produce more foliage on the plant. This research was conducted to study the influence of topping and application of gibberellic acid on vegetative and reproductive growth of African marigold as a bedding plant. In this study, topping as the first factor at three levels (0, 45, and 90 days before transplanting) and gibberellic acid as the second factor at four levels (0, 100, 200, and 300 mg L-1) were applied in a pot experiment outdoor under a factorial experiment with a completely randomized design, 4 replications in each treatment (4 pots in each replication). The seeds were planted in late summer. Then, approximately 7 cm long seedlings with six leaflets were transferred to pots. Plants were treated with gibberellic acid and topping 15 to 20 days after transplanting. Foliar spraying was carried out at three stages with 10 days' intervals. Distilled water was sprayed on control plants. Results showed that using of gibberellic acid combined with a topping treatment increased the amount of chlorophyll index, plant height, length, and lateral roots volume. The number of opened flowers, bud and stem diameter had the highest performance at 120 days after spraying with 100 mg L-1 gibberellic acid. Therefore, topping combined with gibberellic acid at the concentration of 100 mg L-1 increased flowering and most other characteristics studied.

As soon as Nitric Oxide (NO) known as a new biological agent in plants and animals, biological branches of sciences like medicine, biochemistry, physiology and genetics have paid special attention to it. NO is a very reactive gas shape free radical which has attracted much attention during recent years. This compound is produced by the plant and it has increased the shelf life of some fruits, vegetables and cut flowers in low concentrations. NO is mostly synthesized from enzymatic and non-enzymatic pathways whose enzymatic biosynthesis pathway is done by reductase nitrate biosynthesis pathway through the cytosol, also it is known as an important and very reactive signaling molecule with short life which is produced by a group of enzymes known as synthesize NO which transforms Larginine to L-citrulline and NO. It has been revealed that plants use NO as a growth regulator which regulates and modifies antimicrobial defensive responses. Recently, it has been approved that this material plays a vital role in regulating the normal physiological activities of plants such as pores closing, aging, increasing the vase life of cut flowers after harvesting, respiration and photosynthesis, antioxidant enzymes activities and growth.

Among the most commonly used branching-inducers are gibberellic acid (GA3) and N 6-benzyladenine (BA) which are synthetic cytokinins that have been shown to increase shoot number in some plant species. The aim of this research was studying the effects of synthetic branching agents on a foliage plant. The effects of GA3 and BA on Ficus benjamina plant was evaluated under greenhouse condition. Plants were treated with foliar application of GA3 and BA at 0, 100 and 200 mg L-1. The plants that were treated with GA3 and BA at 200 mg L-1 showed the highest number of leaves and plant height. Foliar application of 200 mg L-1 GA3 + 200 mg L-1 BA increased photosynthetic pigments. The highest rate of soluble carbohydrates and reducing sugars were belonged to 200 mg L-1 GA3 and 100 mg L-1 GA3 + 200 mg L-1 BA, respectively. Results indicated that application of 200 mg l-1 of GA3 + BA significantly promoted morphological growth, chlorophyll and carotenoid content, reduced sugars and soluble carbohydrates in F. benjamina.
