Effect of growth regulator paclobutrazol on size fitting of basil as a potted plant

Abstract Basil (Ocimum basilicum L., Lamiaceae) is an herbal species cultivated primarily for culinary and aromatherapy. plant height could reach more than 60 cm, the plants tend to elongate, particularly in low-light environments. Our current study examined potential uses of growth retardant paclobutrazol control sweet basil improve potted basil’s ornamental quality. The treatment tested was concentration at 0, 5, 10, 20 ppm, applied as 100 mL media drenching per pot five weeks after planting. were water-drenched using same volume time. treated with PBZ 10 ppm or had significantly shorter, smaller shoot canopy diameter, node leaf number control, but a similar branches control. showed compact bushy ratio 1.5. Higher chlorophyll, indicated by higher index value, recorded only compared other concentrations. responses not different from those therefore use lower (10 ppm) preferable. Further studies should examine whether repeated applications effective producing shorter plants.
