Abstract: (53 Views)
Most bulbous ornamental plants, like gladiolus (Gladiolus grandiflora L.), need three long periods for the growth of their bulbs, which is a major challenge for their propagation. Determining the best hormonal composition for increasing the growth of corms is a major problematic process in the growth and propagation of gladiolus plants. For this purpose, a factorial test in a Completely Randomized Design was performed using three GA3 concentration levels (0, 100 and 200 mg/l) in addition to three concentration levels of BAP (0, 50 and 100 mg/l) for soaking the corms of two Gladiolus cultivars, White (white prosperity) and Red (cultivar, Red) with five replications at green house conditions. Corms, after soaking in different hormone solutions, were planted in plastic pots with an appropriate soil mixture. Pots were then put in a greenhouse under standard light and temperature conditions with a regular irrigation regime. Plant samples were harvested between 15 and 30 days after planting and were used for the analysis of some growth and propagation traits. According to the results, Hormone treatment with 100 mg/l GA3 without BAP for leaf length, root number and corm weight for both cultivars showed a great increase. Treatment with 100 mg/l BAP without GA3 resulted in the maximum value for leaf number in the white cultivar. Also, 50 mg/l BAP without GA treatment for corm number at both cultivars showed the best results. As a conclusion, appropriate hormonal concentrations of GA3 for growth parameters and BAP for propagation parameters could be suggested for gladiolus plant culture and propagation.
