This studywas aimed at investig at ingthe production of phytochemicals thatdetermine fruitquality, and
evaluating growth characteristics of mature strawberry plants during cultivation under three different
wavelengths (blue, red and blue plus red) of LED light. Cultivation was conducted in two separate locations, namely, a growth chamber (GC) illuminated with LED lights as the sole light source and a plastic
greenhouse (PG) which was given supplemental LED lightin addition to ambientlight. It was noted that
leaves of plants cultivated in the GC under LED lights displayed elevated levels of chlorophyll compared
with those cultivated in the PG. In contrast, plants cultivated in the PG with supplementary LED lights
yielded much higher production of fruits than those cultivated in the GC. Moreover, fruits harvested in
thePGweredemonstratedtocontainhigher levelsoforganic acids thanthoseharvestedintheGC.When
the effects of different LED lights were examined, a remarkably higher production offruits was achieved
in the PG when ambient light was supplemented with either blue LED light or combined blue and red
LED light. Furthermore, it was alsonoted that greater accumulationof organic acids and phytochemicals

light was supplemented with either red LED light or combined blue and red LED lights.
