This study was conducted inside the plastic house of the Agricultural Research and Experiment Station of the Agriculture College - University of Kirkuk/Iraq, during the growing season 2020/2021. To study the effect of spraying the growth regulator of benzyl adenine in three concentrations (0, 30, 60) mg.L−1 and licorice root extract in three concentrations (0, 3000, 6000) mg.L−1 on some growth characteristics and chemical content of strawberry plants of Rubygem type. The obtained results were summarized that spraying with a concentration of 60 mg.L−1 of the growth regulator benzyl adenine BA led to a significant superiority in most growth characteristics and chemical content of strawberry plants (leaf area, leaves number, leaves area, dry matter in plant, leaf content of chlorophyll and nitrogen total) where reached (95.81 cm2, 15.78 leaf. plant−1, 1513.93 cm2, 38.68 %, 28.66 %, 3.24 %) respectively. While spraying with concentrations (30 and 60 mg.L−1)of benzyl adenine was significantly superior to the control treatment in the phosphorous and carbohydrates content of leaves. Spraying with a concentration of 6000 mg.L−1 of licorice extract significantly increased in most of the study traits (dry matter in plant, leaf content of chlorophyll, nitrogen, phosphorous and carbohydrates total) where reached (39.06 %, 25.69 mg.g−1, 3.09 %, 0.334 %, 3.38 %) respectively. Spraying with a concentration of 3000 mg.L−1 of licorice was significantly superior in the characteristics of leaf area and Leaves area, which reached (85.08, 1303.18) cm2 respectively.

Effect of Floral Preservatives and Growth Regulators on Post Harvest Life of Gladiolus (Gladiolus grandiflorus L.) cv. American Beauty

A Postharvest experiment was conducted to maximize the vase life of gladiolus using different preservative solution in department of Horticulture, Kalasalingam School of Agriculture and Horticulture. In this experiment the treatment consisted of two preservative chemicals and two growth regulators viz., 8-Hydroxy quinoline sulphate @ 300 ppm Silver nitrate @ 50 ppm, Benzyl adenine @ 20,40,60 ppm and Gibberlic acid @ 10,25,40 ppm along with sucrose @ 4 per cent with distilled water as control. The results of this experiment revealed that the maximum water uptake, transpirational loss of water, water balance, fresh weight change, percentage of opened florets, floret diameter, longevity of floret, vase life was recorded in T2 (8-HQS @ 300 ppm + sucrose 4% + BA @ 40 ppm), when compared to control. Some parameters like optical density of vase solution, days taken for the basal floret to open in vase and the percentage of wilted florets were observed least in T2 (8-HQS @ 300 ppm + sucrose 4% + BA @ 40 ppm). T5 (8-HQS @ 300 ppm + Sucrose 4% + BA @ 40 ppm) solution was found best to extend the vase life of gladiolus.

Micrografting Compatibility Between Two Almond Cultivars and Four Wild Species

Micropropagation and micrografting techniques are important methods used to obtain high quality plants. This research aimed to investigate the effect of wild almond species (Prunus communis, P. orientalis, P. korschinskii, and P. arabica) on the success of micrografting almond cultivars (Prunus dulcis cvs. Shami Furk and Dafadii)and determine which combination of growth regulators lead to the highest rate of multiplication in micrografted cultivars. The shoot tips were grafted onto the rooted rootstocks by inverted T-budding. The results indicated that Murashige and Skoog (MS) medium, supplemented with 1 mg/l benzyl adenine (BA), 0.1 mg/l indole-3-butyric acid (IBA) and 0.2mg/l gibberellic acid (GA3), achieved the highest shoot multiplication with an average of 5.31 and 3.67 shoots per explant and an average of 6.23cm and 4.98cm shoot length in cultivars Shami Furk and Dafadii, respectively. The highest grafting success rates were 80% and 74.26% obtained from Shami Furk/P. arabica and Dafadii/P. arabica combinations, respectively, while the lowest success rate was 50.63% with the Dafadii/P. orientalis combination. The liquid MS medium supplemented with 0.5 mg/l BA + 0.1 mg/l IBA achieved the highest micrografting success and scion shoot length. This research can be used to improve almond cultivation.

Effect of putrescine and benzyl adenine on growth, flowering and post-harvest keeping quality parameters in chrysanthemum (Chrysanthemum morifolium Ramat.)

The experiment was conducted with the objective to study the effect of different anti-senescence compounds like putrescine and benzyl adenine (BA) on vegetative, floral, and post-harvest keeping quality of chrysanthemum cv. Punjab Shyamli. The experiment was conducted in a randomized block design (RBD) and replicated thrice. Putrescine (@ 50, 100, and 150 ppm) and benzyl-adenine (@ 100, 150, and 200 ppm) were sprayed twice on cv. Punjab Shyamli (spray type and pompon) at bud initiation stage and at fully developed flower buds. Control plants were sprayed with normal water. Floral parameters were delayed and the vase life of cut stems was enhanced by benzyl adenine @ 200 ppm. The maximum delay of flower opening stage (116.33 days), number of sprays (5.00), and vase life (27.22 days) were obtained with benzyl-adenine @ 200 ppm treatment. The flower diameter was 4.53 cm with benzyl-adenine @ 200 ppm compared to 2.87 cm in control.

Physiological characteristics and vase life responses of rose cut flowers (Rosa hybrida L. cv. ‘Royal Baccara’) to benzyl adenine and 1- metylcylcopropene

+prolonging vase life and decreasing post-harvest losses are considered a basic strategy towards sustainable development of agriculture, and the application of growth regulators, e.g. benzyl adenine(BA) and 1-metylcylcopropane(1-MCP), is one of the practical methods for them. The effects of benzyl adenine(BA) and 1-metylcylcopropene(1-MCP) on some biochemical characteristics and vase life of rose cv. ‘Royal Baccara’ (Rosa hybrida L. cv. ‘Royal Baccara’), were explored in a factorial experiment based on a randomized complete block design with three replications in 2017. The factors included BA at three levels of 0 (control), 75 and 150 ppm and 1-MCP in three levels of 0 (control), 1 and 2 µl/L-1. The results showed that the maximum soluble protein content was observed in 150 (ppm) BA+ 2 (µl.L-1) 1-MCP treatments on the second, fourth, sixth, and eighth days. The results of this research revealed that BA at the rates of 75 and 150 ppm and 1-MCP at the rates of 1 and 2 (µl.L-1) enhanced soluble protein content by 10.49, 13.37, 15.18, and 18.18 percent as compared to the control, respectively. The results showed that the maximum proline content was related to the control and the minimum content was observed in the plants treated with 150 (ppm) BA+ 2 (µl.L-1) 1-MCP. The endoproteases enzyme content was slightly decreased on the eighth day, indicating the efficacy of BA and 1-MCP in inhibiting the senescence process and prolonging vase life of rose flowers. The results showed that the application of 1 or 2 μl.L-1 1-MCP and 150 mg L-1 BA can improve the vase life of cut roses

Micropropagation of Capparis spinosa through plant tissue culture technology

The study was conducted to investigate the effect of adding different concentrations of plant growth regulators of Benzyl adenine BA, KIN and 2 iP to MS nutritional medium on the growth of single nodes of Capparis spinosa plant. The results showed that in plant length factor the treatments of 2 and 1 mg / liter 2iP were significantly higher compared with the other treatments and the obtained plants reached average length of 3,3.3,1 cm respectively in these treatments, while for the average number of branches and leaves factors, the treatment 2 mg / liter of BA was significantly higher compared with other treatments, the produced plants arrive to 3.6 branches and 14.1 leaves. For rooting system, the treatment of MS supplemented with IBA growth regulator with a concentration of 2 mg / liter was significantly higher for both length and number of roots. The obtained plants were adapted using different treatments but the treatment of mixture peat moss and sand 1: 2 was the best
