摘　　要：为了研究白掌组培苗在新型光源发光二极管(LED)下的生长状况,以亮叶白掌为试验植物材料,采用以性能稳定的超高亮度红光LED(主波长640 nm)和超高亮蓝光LED(主波长464 nm)为光源材料,探讨了新型光源LED对白掌试管苗移栽后生长的影响,研究适合白掌组培苗移栽后生长的光质条件。结果表明:株高最大值出现在50%R+50%B处理下。在叶长和叶幅方面,光质比为80%R+20%B时达到最大值,且与对照处理间有显著性差异;在根数和根系活力方面,80%R+20%B处理下达到最大值。在根长方面,50%R+50%B处理下达到最大值。在鲜重和干重方面,白掌组培苗在80%R+20%B处理下都达到最大值。在叶绿素含量方面,只有在50%R+50%B处理下高于对照处理,其他的处理也都低于对照处理。综上分析,80%R+20%B处理的白掌组培苗移栽后生长状况最好。In order to study on application of novel radiation（LED） resource in Spathiphyllum floribundum in vitro, the purpose of this experiment was to get high-quality in vitro and large-scale production, adopted theultra bright red（R） blue（B） LED as light emitting materials, to use bright leaves of Spathiphyllum floribundum the experiment plant material to explore the effectiveness of light-emitting diodes and the coldcathode fluorescent lamp in the production for transplanted Spathiphyllum floribundum jamesonii in vitro, todiscuss the best light quality for transplanted Spathiphyllum floribundum in vitro large-scale production and todiscuss the perspective of novel radiation resource LED in Spathiphyllum floribundum in vitro production. Theresults showed that：the stem length reached the maximum in the LED of the red/blue ratio of 5：5. The leafblade and blade width reached the maximum in the LED of the red/blue ratio of 8：2, and there was significantdifference between them and CK. The roots reached the maximum in the LED of the red/blue ratio of 8：2. Theroot length reached the maximum in the LED of the red/blue ratio of 5：5. The fresh weight and dry weight allreached the maximum in the LED of the red/blue ratio of 8：2. Only in the LED of the red/blue ratio of 5：5, thechlorophyll content was higher than CK. The dry matter rate reached the maximum in the LED of the red/blueratio of 7：3. But the root vigor reached the maximum in the LED of the red/blue ratio of 8：2. To sum up, thetransplanted Spathiphyllum floribundum in the LED of the red/blue ratio of 8：2 was under the best growth condition.
