| 摘 要： | 研究三基色荧光灯、LEDs红光、LEDs蓝光和LEDs白光对水稻幼苗生长的影响。结果表明,红光对水稻幼苗茎的伸长生长具有明显的促进作用。蓝光下水稻幼苗地上部分干物质积累的百分比最高,但4种光下差异不显著(P＜0.05)。叶绿素含量测定结果表明,蓝光和白光比红光更利于水稻幼苗叶绿素的合成。三基色荧光灯下水稻幼苗根长最长、红光次之、蓝光和白光下最短。四种光下根干重差异均不显著,但蓝光处理下水稻幼苗根干重百分比显著低于三基色荧光灯处理。通过分析得出,使用LEDs光源对水稻幼苗进行培养是可行的。

| 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(P＜0.05). 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． |
