Abstract
ABSTRACT The consumer's constant search for novelties in the area of ornamental plants has inspired the use of species that are normally used for other purposes, such as fruit-bearing plants, to be introduced into floriculture. The physalis, a fruit-bearing plant, with a beautiful accrescent fruiting calyx that envelops the berry, can be used for these purposes. However, this plant can reach 70 cm high, which makes it unviable to be used as an indoor plant. The objective of this research was to decrease the size of the physalis (Physalis angulata) for ornamental use, pot it and apply the plant growth regulator Paclobutrazol (PBZ). The PBZ growth regulator was applied only once, via foliar spray at the concentrations of 0, 30, 60, 90, 120 and 150 mg a.i L- 1, as well as via irrigation in the substrate at concentrations of 0, 5, 10, 15, 30 and 60 mg a.i L- 1. Along with the quantitative variables, a plant acceptability test was carried out when it was considered ideal for commercialization. The obtained results clearly show that it is possible to reduce the size of the physalis for use as a potted plant by using PBZ with foliar applications at the concentration of 90 mg a.i L-1 or by using irrigation applications directly in the substrate at a concentration of 5 mg a.i L-1.

PBZ (Paclobutrazol) ([(2RS-3RS)-1-(4clorofenil)4,4-dimetil-2-(1,2,4-triazol-1-y)-pentan-3-ol]) is a plant growth regulator widely used in floriculture and can be applied by both foliar spray or in substrate form (Syngenta, 2012; Zeneca, 2015)

Summary
The consumer’s constant search for novelties in the area of ornamental plants (Noordegraaf, 2000) has inspired the use of species that are normally used for other purposes, such as fruit-bearing plants, to be introduced into floriculture. The physalis (Physalis angulata L.), known for its delicious fruit (Rufato et al, 2012), could become a good alternative for the floriculture sector, with its beautiful calyx that envelops the berry, its many branches and alternating bright green leaves. Reducing the size of ornamental plants is frequently performed with plant growth regulators. They act within the plant, reducing elongation of the internodes (Silva et al, 2003). PBZ (Paclobutrazol) ([(2RS-3RS)-1-(4clorofenil)4,4-dimetil-2-(1,2,4-triazol-1-y)-pentan-3-ol]) is a plant growth regulator widely used in floriculture and can be applied by both foliar spray or in substrate form (Syngenta, 2012; Zeneca, 2015)
