Abstract. Cuttings of Epipremnum aureum (Linden & André) Bunt. were soaked for
5 seconds in 5% Folicote or Stressguard antitranspirant solution, planted immediately
or after 6 hours, and misted or not misted during the daylight hours for 2 weeks.
Neither antitranspirant affected the growth of misted cuttings. However, in nonmisted
cuttings, Folicote resulted in delayed first leaf unfolding and small plants. Misting
improved shoot growth relative to not misting. In a second experiment, Stressguard
sprayed on leaves of stock plants resulted in slow growth of cuttings taken from them,
while Folicote had no effect. Water stress induced by delayed planting resulted in water
loss and slow lateral shoot growth in both experiments. Application of uniconazole at
the four-leaf stage at 0.05 to 0.4 mg/0.5-liter pot reduced stem elongation, leaf count,
and the length of nodal roots. Uniconazole increased individual leaf size on the main
shoot and promoted the growth of basal lateral shoots. While stem and total plant dry
weights were reduced, total leaf dry weight was not affected by uniconazole. Uniconazole
continued to provide good control on the elongation of newly emerged lateral
shoots and promoted the production of more and larger leaves when evaluated 4 weeks
after the main shoot was severed above the fourth basal node. Chemical name used:
(E)-1-(p-chlorophenyl)-4,4-dimethyl-2-(1,2,4-trizol-1-yl)-1-penten-3-ol (uniconazole).
