Morphophysiology and quality of yellow passion fruit seedlings submitted to inhibition of gibberellin biosynthesis

The aim of this study was to verify if a growth reduction yellow passion fruit seedlings’ morphophysiology and quality could be changed by paclobutrazol applied through seedling immersion. experiment conducted in greenhouse, with seedlings grown polyethylene tubes (290 cm3), substrate. At 40 days after sowing, the were immersed an aqueous solution at concentrations 0, 50, 100, 150, 200 mg L-1. randomized block design, five treatments (paclobutrazol concentrations) four replicates. 15 30 treatment, characteristics evaluated. end assay, destructive evaluations related mass determination, total leaf area, index performed. Paclobutrazol treatment induced restrictions growth, except for fresh dry root mass. Based on these characteristics, increase values verified. quality, defined major value Dickson smaller robustness index, higher when submitted treatment.
