Ornamental plants are cultivated worldwide. Chrysanthemum is classified as one of the most important cuts and potted flowers in most countries. The consumer’s expectation is to find small and compact plants full of inflorescences. To meet these demands, growers tend to use plant growth retardants.
Three Chrysanthemum indicum L. varieties (‘Smola White’, ‘Arber’, and ‘Vienna White’) were assessed by using four plant growth regulators (PP–Bumper 250 EC; CC–Stabilan SL; MP–Medax Top SC; and PD–Toprex SC). Results indicate that treated plants show a significant decrease in the assessed parameters, although in some cases growth could be a variety–dependent factor. It can also be concluded that retardants inhibit chrysanthemum growth.
PD treatments greatly inhibited the growth of the plant, and also had a negative effect on inflorescences. In conclusion, the present work strengthens the possibility of using retardants as plant growth inhibitors in Chrysanthemum cultivation.
