Paclobutrazol (PBZ) and sodium chloride (NaCl) were sprayed on strawberry (Fragaria × Ananassa Duch. cv. Selva). The experiment was carried out in a factorial randomized complete block design with three replications in greenhouse conditions. Plants were treated with two levels of NaCl (0 and 20 mg L-1) and four levels of PBZ (0, 30, 60 and 90 mg L-1). Results showed that PBZ is an important factor for increasing the generative traits and fruit quality, but not on vegetative traits. The highest leaf number, leaf area, petiole length, and total soluble solid (T.S.S.) percent were observed in control plants, while highest fruit number, fruit weight, fruit set, flower number and yield of strawberry were obtained in plants treated with 90 mg L-1 PBZ. Foliar application of PBZ prior to flowering is recommended to increase the yield of strawberry.
