“…Costa Junior et al (2016) observed that plants of this same ornamental pineapple hybrid, grown in the field in the same region, responded to floral induction when they had a height of 60 cm and leaves length 'D' of 53 cm. Factors such as photoperiod and temperature environmental conditions may have interfered in the results obtained (Cunha, 2009;Küster et al, 2017;Xin et al, 2019). Nascimento et al (2018), some cultivars of ornamental peppers, such as Peloteira and Jalapeño, showed resistance to ethylene when subjected to increasing concentrations of PBZ.…”

“…In edible cultivars, the nutritional stage, type, seedling weight and planting time are factors that interfere in the response of plants to floral induction (Reinhardt et al, 2018). In addition, it is clear that the response to natural or artificial induction is generally determined by the age and size of the plant, as well as by environmental factors in the growing region (Cunha, 2009;Fernandes et al, 2018;Ribeiro et al, 2019).…”

The expansion of residential areas has increased the demand for exotic and increasingly compact landscape plants. In this context, this work aimed to evaluate the effects of paclobutrazol (PBZ) and the timing of ethylene application on growth reduction and flowering anticipation in ornamental pineapples grown in pots. The randomized block design was used with factorial arrangement (2 x 5) and 4 replications and 4 plants per plot. The primary treatments are the presence and absence of PBZ. The secondary treatments were five times of floral induction with ethylene: 90; 120; 150; 180; 210 days after transplanting (DAT) the seedlings into the pots. It was evaluated the variables: height ratio between the heights of the pot and the plant; rosette diameter; leaves length ‘D’ and flowering index. At 255 DAT, although the plants did not respond to floral induction with ethylene, only those treated with PBZ were more compact and had different characteristics such as smaller size and a ratio below 1/3 of the height of the vase in relation to the plant that to favor its commercialization, in pot.
