“…The other possible reason for the significant increase in the vegetative growth characteristics could be attributed to the effect of gibberellins on the activity of the photosynthesis process and thus increasing the efficiency of utilization of the products of the photosynthesis process by the plant. These results are also in line with those of [28][29][30][31][32][33][34].…”

This study was conducted inside the wooden canopy of the Department of Horticulture and Landscape Engineering / College of Agriculture and Forestry / University of Mosul during the agricultural season 2022-2023. To study the effect of spraying with different concentrations of calcium chloride (0, 500, 1000) mg. L-1 and spraying with gibberellic acid at concentrations of (0, 100, 200) mg. L-1 and the interaction between them in vegetative of two cultivars of Gladiolus Gladiolus hybrid. L. They are Nova lux with yellow flowers and Trader Lux with red flowers. The corms were planted on 17/3/2022, then sprayed 30 days after planting the corms with three sprays and three concentrations of calcium chloride (0,500, 1000) mg.L-1 The plants were also sprayed with gibberellic acid, with three sprays and three concentrations (0, 100, 200), The period between one spray and another was two weeks. The spraying was done with gibberellic acid after 35 days of planting the corms. The study was carried out using a factorial experiment in the design of completed randomized sectors R.C.B.D within split plots with three replications, each experimental unit included (7) cormat for each replicate. The research results of were analyzed statistically with the (SAS) program and tested statistically using Duncan’s multinomial test at the probability level of 0.05. It was found that the red cultivar recorded the largest plant height, which reached 129.905 cm, the largest leaf length, which reached 102.584 cm, and the largest number of leaves, which reached 9,980 leaves. Plant-1, and the largest leaf area of the plant, amounting to 401.656 cm2. plant-1, and the largest dry weight of the leaves, amounting to 12.567 g. The yellow variety plants also recorded the largest values for the percentage of total chlorophyll in the plant, which amounted to 0.984%. The treatment with gibberellic acid at a concentration of 200 mg also resulted. L-1 led to a significant increase in all studied traits.

“…Similar findings concerning the increase in bulb diameter were reported for gladiolus. The increase of weight of corms with the application of GA3 can be attributed to its ability to increase the yield of photosynthetic products, which was reported in freesia by Żurawik and Placek (2013) and in gladiolus by Arora et al (1992), Siraj and Al-Safar (2006), and Kumar and Misra (2012).…”

Freesia hybrida is one of the most important cut flowers with a short vase life. The present study was conducted to explain the effect of the two planting dates December 1st and 15th and soaking corms before planting in gibberellic acid at concentrations of 0, 75, and 150 mg·L−1 on the growth, flowering, and flowers quality of Freesia hybrida ‘Corona’. A larger diameter of the inflorescence stem and floret head, fresh weight of inflorescence, and longer vase life were obtained when planted on December 1st. Soaking the corms in a GA3 solution of 150 mg·L−1 before planting significantly extended the vase life compared to the control. Finally, it can be concluded that the planting of corms soaked in a solution of 150 mg·L−1 GA3 on December 1st in unheated greenhouses can improve the growth, development, and quality of flowers of Freesia hybrida ‘Corona’.

“…Maximum corm weight (14.90 g) was produced by the plants treated with gibberellic acid of 150 mg L -1 and 200 mg L -1 . Maximum corm weight were obtained in Red Advance, it might be due to the best adaptation of gladiolus cultivar and more accumulation of photosynthates and carbohydrates production in which it had obtained a good and well developed plants, as a result it promoted the best corm weight (Yousif et al, 2006). More food is reserved by larger size corms which help in growth and development, with the combination of 150 mg L -1 gibberellic acid increases the single corm weight (Bhat et al, 2009;Hossian, 2011;Amin, 2013).…”

Ornamental plants like gladiolus are suitable option for growers with lower amount of land, as they are highly economic and have lower cost of production. An experiment was conducted with aim to study the exogenous application influence of gibberellic acid on vegetative and reproductive characteristics of gladiolus was conducted under the subtropical conditions. The experiment was laid out in two factors randomized complete block design and replicated three times. Gibberellic acid (GA3) was used in different concentrations (0, 50, 100, 150, 200 mg L-1) to corms of two cultivars of gladiolus (‘White Prosperity’ and ‘Red Advance’). Results showed that most of the parameters were significantly influenced by gibberellic acid at 200 mg L-1. The maximum sprouting, number of leaves plant-1, daughter corms per plant, less number of days to corm sprouting, days to spike emergence and flower opening were recorded in plants treated with 200 mg L-1 gibberellic acid (GA3). ‘Red Advance’ produced more number of leaves plant-1, corm diameter, corm weight, and less number of days to spike emergence and flower opening. It can be concluded from the present findings that the treatment of corms with 200 mg L-1 gibberellic acid can improve the growth and yield of cultivar Red Advance than White prosperity under the subtropical conditions.
