摘要： 本文研究LED光源不同光强对甘薯组培苗生理性状的影响,为新型人工光源在植物组培上的应用提供理论依据。试验利用波长为660nm(±20nm)红光与450nm(±20nm)蓝光发光二极管(LightEmittingDiode,LED)作为人工光源,设置5个LED光源处理区,分别为LED1(12.49μmol·m-2·s-1)、LED2(14.15μmol·m-2·s-1)、LED3(18.85μmol·m-2·s-1)、LED4(19.66μmol·m-2·s-1)、LED5(22.50μmol·m-2·s-1),以3根荧光灯处理(46.82μmol·m-2·s-1)为对照(CK),选用甘薯组...
