Abstract

Zinnia elegans Jacq. is one of the ornamental plants potential to be used as a potted ornamental plants. The problem to be resolved is the size of the plant can reach 1 m, so it is necessary to modify the plant height into 20 cm to 25 cm using retardant (plant growth regulator), called daminozide. The purpose of this study was to determine the best concentration and soaking time using daminozide to inhibit the growth of zinnia. The research was conducted at Mangkuyudan 57, Yogyakarta. This research was arranged in a factorial design with 3 blocks as replication. Different concentrations of daminozide were used as first factor with three levels (1 g.L-1, 2 g.L-1, and 3 g.L-1) and soaking times were used as the second factor (12 h, 24 h, and 36 h). The data were analyzed using analysis of variance and continued with HSD-Tukey at the α = 5 %. The results showed that there were an interaction between daminozide concentration and soaking time in the height of Z. elegans. There were also positive correlation between plant height, number of flower, and flowering period. The best combination of daminozide concentration and soaking times were 2 g.L-1 and 12 h. This treatment gave the best height that fit to the criteria of a potted plant which was 20.08 cm. However, it reduced flower’s diameter, number of flowers, and canopy’s size.

Abstract

Generally, cucumber plants have more male flowers than female flowers. The fewer number of female flowers is one of the problems of cucumber production. Flowering regulation can be performed by applying growth regulators and water management. The study aims to determine the effects of paclobutrazol concentrations and watering frequencies on the flowering ratio of cucumber plants. The experiment was arranged in a factorial Randomized Completely Block Design at the Agricultural, Food, and Fishery Extension Center, Seyegan, Yogyakarta. The first factor was the paclobutrazol concentrations consisting of four levels (a control, 0.187 mL.L-1, 0.375 mL.L-1, and 0.562 mL.L-1). Meanwhile, the second factor was the watering frequency consisting of three levels (once a day, once every two days, and once every three days). The observed data were performed using the analysis of variance (ANOVA) and followed with Duncan’s Multiple Range Test at α= 5 %. The paclobutrazol concentrations resulted in a significant effect on all of the observed variables. Meanwhile, watering frequencies showed no significant effect on the male flowers, female flowers and ratio of male to female flowers in cucumber. There was an interaction effect of paclobutrazol concentration and watering frequency on the plant height and flowering age of cucumber plants. The treatment of paclobutrazol at a concentration of 0.375 mL.L-1, decreased of male flowers and increased of female flowers, reducing the ratio of male and female flowers of cucumber plants at various watering frequencies.-1
