Abstract
Abstract Codiaeum variegatum (L.) Blume var. pictum (Lodd.) Mull, Agr. ‘Bravo’ and ‘Normal’ were produced for 8 months under light levels of 950, 650, or 350 μmol s-1m-2 before being held for 4 months indoors under 6, 12, or 24 hr light duration using either cool-white fluorescent (CWF) or incandescent (INC) lamps. After 8 months of growth in production, plant width and leaf length increased whereas leaf number, thickness, and variegation decreased as production light level decreased. The best quality plants with moderate variegation and adequate growth were those produced under 650 μmol s-1m-2. After 4 months indoors, ‘Bravo’ tolerated interior light conditions more successfully than ‘Norma’. Plants previously produced under 350 μmol s-lm-2 retained more leaves and maintained better plant quality than other production light treatments. Leaf retention was best with 12 hr of postproduction light duration. Adequate lighting to maintain the quality of properly acclimatized plants was provided by either CWF or INC lamps.
