Abstract Soaking French marigold seeds in growth regulator solutions produced larger reductions in seedling height than foliar sprays. Seeds soaked in 1 to 5 ppm uniconazole solutions for 0.15, 5, or 45 min resulted in plants that were up to 23% shorter than controls at 30 DAS, whereas foliar applications of 10 to 20 ppm uniconazole solutions resulted in plants 18% shorter than controls at 14 DAS. French marigold seedlings from seeds soaked in 60 pm ancymidol for 5 or 45 min were 5 or 6%, respectively, shorter than controls. Foliar spray applications of 25 or 100 ppm ancymidol to French marigold seedlings resulted in plants 8% shorter than controls. Chlormequat solutions applied either as a seed soak (1000–5000 ppm) or foliar spray (500–3000 ppm) did not reduce French marigold seedling height. Emergence of French marigold seedlings from seeds soaked in uniconazole, ancymidol, or chlormequat solutions was not different from that of control seeds. No effect on seedling height or emergence was found when soaking celosia seeds in uniconazole, ancymidol, or chlormequat solutions. Spraying celosia seedlings with uniconazole, ancymidol, or chlormequat solutions did not reduce seedling height.

Spray Applications

Abstract Pink polka-dot plant, Hypoestes phyllostachya Bak., was treated with one or two foliar spray applications of Bonzi (paclobutrazol) (25, 50, or 100 ppm), Cycocel (chlormequat chloride) (3500 ppm) or B-Nine (daminozide) (3500 ppm) to suppress shoot elongation. One or two applications of 3500 ppm Cycocel (chlormequat chloride) retarded shoot elongation, resulting in consistently mounded plants. Bonzi (paclobutrazol) and B-Nine (daminozide) also suppressed shoot elongation but to a lesser degree, and plants were not uniform.

Spray Applications

Paclobutrazol was applied as a foliar spray, root-medium drench, and impregnated spike to `New Gold' lantana grown in 2.8-liter pots. Plants were treated 14 June 1993 at rates of 0, 0.5, and 1.0 mg a.i. paclobutrazol/pot and were harvested 27 July 1993 when control plants required further pruning. Impregnated spikes reduced plant size and flowering to a greater degree than spray applications. Drenches reduced root dry weight and biomass compared to spray applications. Plants treated with 0.5 and 1.0 mg a.i. paclobutrazol/pot were not different in regards to plant growth and flowering. Compared to nontreated controls, plants treated with paclobutrazol had a reduced growth index, decreased shoot and root dry weight, and fewer flowers with open florets. All plants in the study were marketable, even though growth control was considered excessive. Lower rates than used in this study should be considered for controlling growth. These results suggest that impregnated spike formulations of paclobutrazol may control plant growth in pine bark-based media.

Postharvest Longevity

Sunflower to be used in ornamental floral arrangements need to be free from damage, and have longer shelf life. The aim of the present study was to evaluate the effect of acetylsalicylic acid (ASA) on the postharvest longevity of ornamental sunflower. Floral stems of the cultivar Vicent’s Choice from Sakata Seed were placed in flasks containing 350 mL of solution containing 0, 200, 400, 600, 800, or 1000 mg of ASA per liter of distilled water. Aspirin® (acetylsalicylic acid) tablets were used as the source of salicylic acid. Grades from 0 to 5 were assigned every day, according to a pre-established criteria for assessing the longevity and quality of the inflorescences. The data were subjected to analysis of variance, Tukey’s test (t = 0.05%), and regression analysis using Sisvar program. Significant differences were observed in the grades from the sixth to the tenth day of treatment, but not in the total longevity. Treatment with 400 mg L-1 of ASA improved the commercial longevity to an average of 9 days, about 4 days more than the control (0 mg L-1). At 400 mg L-1 dose, ASA prolongs the commercial longevity and maintains the postharvest quality of ornamental sunflower stems. However, at the maximum dose used (1000 mg L-1), the evaluated parameters did not show any improvement over the controls.
