PHOTOREGULATED DICENTRA SPECTABILIS (L) LEM. AS A POTENTIAL POTTED PLANT

Light flux, growing temperature, and growth retardant studies were made on Dicentra spectabilis.
Quality above-ground growth and inflorescence initiation occurred at 144 000 to 352 000 lux-hours/day, but anthesis and greater root growth occurred at the higher light flux.
Inflorescence initiation was faster at 15°C than 22.5°, and at both temperatures there was considerably greater growth than at 30°. Inflorescence initiation did not occur at 30°. Height was effectively reduced by SADH, but not by cycocel.
From the information available, commercial production of the species in long photoperiods seems feasible, but further studies are necessary.
