在室内人工光源照射条件下,探究150μmol·m~(–2)·s~(–1)光强下不同比例的红蓝光对拟南芥(Arabidopsis thaliana)生长发育的影响。以哥伦比亚(Columbia-0)野生型拟南芥为研究对象,采用荧光粉激发型LED作为植物生长光源,以SrSiAlN3为红色基底,调节荧光粉添加量获得不同红蓝光谱,考察不同光照条件下拟南芥萌发率、根长、株高、叶绿素含量和相对电导率等参数的变化规律。结果表明,在荧光粉激发型LED光照调节下的拟南芥具有更高的萌发率、根长、株高、叶绿素含量和相对电导率,且在红蓝光质比为2:1时萌发率(95.63%)和叶绿素含量(26.7)最高;在红蓝光质比为4:5时根长(4.19 cm)较长;在红蓝光质比为4:...

To investigate the effects of different red and blue bands on the growth and development of Arabidopsis, we used the model plant Arabidopsis thaliana Columbia-0 to observe the relation between light quality and plant growth. The phosphor excitation-type LED lighting affords an adjustable light spectrum by adjusting the amount of the nitride-based phosphor SrSiAlN3：Eu~（2＋）. The germination rate, root length, variation in plant height, chlorophyll content, conductivity and other parameters of the model plant under different light spectra were...
