butterflies. Hybrid sage was selected for this study based on its popularity in southern gardens and to determine if a plant growth regulator (PGR) could help control stem height, potentially increasing ease of shipping and handling. In previous work ( Latimer

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

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
