The objective was to evaluate the quality of ornamental pepper seedlings, cultivar Pyramid, in different substrate volumes, with foliar application of paclobutrazol (PBZ).The experiment was carried out at the Mato Grosso do Sul State University - UEMS, in Cassilândia - MS. The experimental design was completely randomized, in a 2 x 2 factorial scheme (growth container x foliar application of PBZ) with four replicates of 36 seedlings each. Plastic trays (cells with a volume of 50 mL) and polystyrene trays (Isopor®, 100 mL cells) were used as containers. The treatments were: polystyrene tray with PBZ application; polystyrene tray without PBZ application; plastic tray with PBZ application and plastic tray without the application of PBZ. Plant height, root length, stem diameter, shoot dry mass, root dry mass, total dry mass, height/stem diameter ratio (H/D), shoot/root ratio (S/R) and Dickson quality index were evaluated. Foliar application of paclobutrazol resulted in robust pepper seedlings with reduced size, suitable and desirable characteristics for ornamental purposes. The polystyrene trays with higher volume cells (100 mL) contributed to the higher quality of ornamental pepper seedlings.
