Abstract

Seedling growth of rice under different light qualities including three-band fluorescent lamps(TFL),red light emitting diodes(R-LEDs),blue light emitting diodes(B-LEDs) and white light emitting diodes(W-LEDs) were studied.The results indicated that R-LEDs significantly promoted the stem elongation of rice seedlings.Under B-LEDs,the biomass accumulation rate of aerial part of rice seedlings was the highest,but there was no difference among all the four light qualities(P0.05).Furthermore,B-LEDs and W-LEDs were more conducive for chlorophyll synthesis in rice seedlings.The longest root of rice seedlings was observed under TFL.There was no difference in root dry and fresh weight under four light qualities.But the root dry and fresh weight ratio under B-LEDs was significantly lower than that under TFL.As a result,the application of LEDs in rice cultivation was feasible.
