The effect of triacontanol on the flowering of Gladiolus (Gladiolus hybridus)

Gladiolus plant is one of the ornamental flower plants that is used as cut flowers. The economic value of cut flowers depends on the length of the stalk along the stalk, the brightness of the color of the petals, and the length of time the flowers are vaselife. Triacontanol compounds
(TA) are long-chain alcohol compounds, and are generally able to stimulate the flowering process and fruit enlargement. The study used a one-factor randomized block design, including four treatments and six blocks. Gladiolus plants aged 15 days after planting have been applied
with TA compounds at concentration levels of 15 g-4.L-1, 30g-4.L-1, and 45 g-4.L-1 through above soils surface, apparently giving different effects on the quality of gladiolus cut flowers. The comes about appeared that TA fertilization at a concentration of 45 g-4.L-1 was the best depending on the age of flower bud appearance, flower harvest age, flower stem length, flower diameter and and 5-day Relative Growth Rate. This study aimed to examine the effects of TA compounds at different concentrations on flowering of gladiolus. TA compounds had a better effect when given in a concentration of 45g-4.L-1 for all observed response variables.
