Hah. Graham et Dr. Decoteau, REGULATION OF BELL PEPPER SEEDLING GROWTH WITH END-OF-DAY SUPPLEMENTAL FLUORESCENT LIGHT, HortScience, 30(3), 1995, pp. 487-489
The influence of end-of-day (EOD), supplemental, cool-white fluorescen
t light on pepper (Capsicum annuum L. cv. Keystone Resistant Giant No.
3) seedling growth and fruit production after transplanting to the fi
eld was investigated. Seedlings were exposed to this light source, whi
ch is high in the red wavebands, from one (1988) or two bulbs (1989) f
or 1 hour before the end of the natural photoperiod. Each year control
plants were exposed to ambient light and received no supplemental flu
orescent light. Before transplanting to the field, seedlings exposed t
o two bulbs were shorter and had smaller leaves than plants in the con
trol treatment. Supplemental fluorescent light treatment, regardless o
f number of bulbs, reduced plant height, leaf area, fruit weight, and
fruit count at the first harvest. Total fruit production was not affec
ted by supplemental light, suggesting no residual effect of the light
treatment during transplant production on total subsequent fruit produ
ction.
