Abstract: The effect of different color temperature white LEDs (Light-emitting diodes) and different combinations of red and blue LEDs on the tissue culture of rose were studied. Results showed that growth of plant materials cultured under the red and blue combination light qualities were significantly better than growth of those cultured under fluorescent and white LEDs in plant height uniform, while the growth of plant cultured under different color temperature white LEDs showed no significant difference from the growth of those cultured under fluorescent lamp. The results of photoperiod on tissue culture of rose indicated that when the LEDs illumination time was not shorter than 14 h·d-1, there was no significant difference in the plant material cultured under the white LEDs and the fluorescent material at 14 and 16 h·d-1. The results of rooting induction showed that plant cultured in different light circusmantance had no significant difference in rose rooting indutcion. All the results indicated that 5 000 K white LEDs could completely replace the fluorescent lamp as a rose tissue culture alternative light source, and 14 h·d-1 photoperiod was enough.

Key words: light, rose, tissue culture, light-emitting diodes (LED)
