Abstract

To increase the strawberry fruit yield in a closed-type plant factory, June-bearing strawberry cultivar ‘Beni hoppe’ plants were grown under white or magenta light-emitting diodes (LEDs) in a growth chamber.
The effects of LED colors on plant growth, fruit yield, and fruit quality were determined, with a focus on spectral distributions, including the red light (R; 600-700 nm) to far-red light (FR; 700-800 nm) (R/FR) ratio and the photosynthetic photon flux density (PPFD; 400-700 nm) to FR (PPFD/FR) ratio.
The R/FR ratio was 9.19 and 2.98 for the white and magenta LEDs, respectively.
The PPFD/FR ratio was 30.22 and 3.98 for the white and magenta LEDs, respectively.
Compared with the effects of the white LEDs, the magenta LEDs resulted in taller plants, longer petioles, and larger central leaflet areas.
There was no significant difference between the white and magenta LEDs in terms of the total number of marketable fruits.
However, the marketable fruit weights (total and average) were significantly greater for the plants grown under magenta LEDs than for the plants grown under white LEDs.
Furthermore, analyses of the firmness of the fruit skin and the fruit soluble solid content revealed the effects of the white and magenta LEDs did not differ significantly.
