develop long flower peduncles that can result in lodging and decreased commercial marketability. Therefore, controlling the height of baby primrose in greenhouse environments is critical to its potential commercial success. Plant growth regulators (PGRs

Poinsettia is an important flowering potted crop in the United States with a wholesale value of over $153 million ( U.S. Department of Agriculture, 2009 ). Poinsettia height can exceed the requirements for commercially acceptable finished plants
Girl’, ‘Big Boy’, and ‘Champion II’ seedlings with application rates of 0, 2.5, 5 or 10 mg⋅L –1 uniconazole at 14, 21, and 28 d after sowing responded similarly in height reduction compared with the control plants for most cultivars and produced plants
Caladiums can be excessively large relative to the container in which they are grown, and plant growth regulators (PGRs) are required for height control. No industry standard has been set for optimal height of caladiums, but plants 25 to 28 cm tall
limit plant height and promote overall compactness. Growers typically manage excessive stem elongation with chemical growth regulators such as PGRs ( Whipker, 2017 ). A concern associated with PGRs is that they are not labeled for all crops. PGRs also
influence of PBZ on increased drought tolerance was due to a reduction in transpiration, shorter plant height, diminished biomass and leaf area, and an increase in stomatal resistance ( Fernández et al., 2006 ). Flurprimidol is a triazole similar to PBZ and
–12.5K water-soluble fertilizer (Jack’s; JR Peter, Inc., Allentown, PA, USA) at a rate of 200 mg·L −1 was applied with each watering with 20% leaching fraction. Data collection Data were collected 6 weeks after transplanting for plant height
One of the environmental concerns in the production of potted plants is the use of plant growth retardants (PGRs) for the control of plant height. In the search for alternatives to PGRs, changes in light quality [e.g., increased red to far
