| Abstract/Contents: | "Bermuda grass (Cynodon dactylon [L.] Pers.ŒC. transvaalensis Burtt-Davy 'Tifton 419') was grown under different color temperatures (5,000 K [dominant wavelength: 450 nm] and 2,700 K [dominant wavelength: 600 nm]) of light emitting diodes (LEDs), and for different durations (eight hours and four hours). The turf was clipped weekly to maintain a height of approximately 20 mm. The dry weights of the clippings were measured, and the plants were harvested at 28 days after treatment. From each treatment, 15 longest stolons was selected, and its number of nodes and length of stem along with the above-ground and below-ground dry weights were measured. It was found that the plant height was significantly higher under the 2,700 K color temperature than under that of 5,000 K. The dry weights were significantly increased as photosynthetic photon flux density (PPFD) increased. However, the changes in the dry weight of the clippings were statistically insignificant under the same PPFD conditions. These results indicate that the 5,000 K color supplemental lighting suppressed upward elongation and developed many leaves in positions closer to the ground surface. The 5,000 K lighting most increased the number of the length of the 30-40 mm internodes and the 2,700 K lighting most increased the number of the length of the 40-50 mm internodes. Thus, the 5,000 K supplemental lighting may be effective for forming dense turf." |
