Abstract
The objective of this study was to investigate the effects of composition
of nutrient solution on the growth and quality of baby leaf vegetables
(tah tsai, romaine lettuce, beet, and red radish) hydroponically cultivated
in a plant factory with artificial lighting (PFAL). Seeds of the four
vegetable crops were sown in urethane sponges and cultivated for 14
days in a PFAL. Light intensity and photoperiod were 110 μmol・m
-2・s
-1
and 16 h・d
-1
, respectively; and air temperature in photo-/dark periods
was maintained at 25/20°C. Tap water was suppied for seven days
after sowing, and then tap water (TW) and the nutrient solutions of
Korea wonshi (KRWS), Japan enshi (JPES), and Yamazaki solution
for lettuce (YMAK) were supplied for seven days. Fourteen days after
sowing, the fresh weight of tah tsai and romaine lettuce was greatest
in YMZK treatment, while there was no significant difference among
nutrient solutions in beet and red radish. When we compared leaf
color using Hunter’s a value, KRWS and JPES increased green color
in baby leaf vegetables, while YMZK increased red color. Total phenolic
content of romaine lettuce was greatest in KRWS treatment, but that
in tah tsai, beet, and red radish showed no significant difference among
nutrient solutions. Results suggest that KRWS enhances the growth and
quality of romaine lettuce, while YMZK is appropriate for enhancing
the growth and red color of beet and red radish hydroponically grown
in a PFAL.
