Growth retardant was applied to improve the quality of Globba winitii (Siam). In vitro propagated plants were transplanted on 21st May into 10 cm pots containing a 1 soil : 3 peat : 1 perlite (by volume) medium and placed directly on the bench. Flurprimidol was applied once as a single foliar spray (0, 7.5, 15, 22.5 and 30 mg l-1) or a soil drench (0.075, 0.15, 0.225, and 0.3 mg/pot [0.25 cm3]) when shoots were 6-8 cm long. Desirable globba height was obtained with a foliar spray of 15 mg l-1 and a soil drench of 0.075 mg/pot. The leaves and canopies of flurprimidol treated plants were significantly smaller than those of untreated ones. Flurprimidol had no significant effect on the time to flowering and number of shoots. The flurprimidol treated plants had darker green foliage than control plants. Chemical name used: a-(1-methylethyl)-a-[4-(trifluorometyloxy)-phenyl]-5-pyrimidine-methanol (flurprimidor).
