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(14.15μmol/m~2·s,R/B=5/1)、LED2(12.49μmol/m~2·s,R/B=9/1)、LED3(22.50μmol/m~2·s,R/B=8/1)、LED4(18.85μmol/m~2·s,R/B=7/1)、LED5(19.66μmol/m~2·s,R/B=3/1),以3根荧光灯处理为对照...
