Abstract

Light-Emitting Diode（LED） is turning into an important research field as a promising irradiation source for plant factory. To determine the influence of LED on growth and photosynthesis of Epipremnum aureum，a fluorescent lamp and two LEDs，the combination of red and blue LED（R/B） = 2.8 and R/B = 4.3，were used with seedling height，leaf number，leaf width，leaf spacing，leaf length，light quality，net photosynthetic rate，intercellular CO2 concentration，transpiration rate，and stomatal conductance being measured after 45 d of growth with three replications. Results of a t test for the a fluorescent lamp and two LEDs showed no significant difference （P＞0.05） for seedling height，leaf number，and leaf width，but significant difference （P＜0.05） for leaf spacing and leaf length，leaf spacing for LEDs decreased，whereas corresponding leaf length increased. With the two LEDs，light quality differences were slight. Also，significant difference （P＜0.05） for net photosynthetic rate，intercellular CO2 concentration，transpiration rate，and stomatal conductance，these indexs with LEDs were higher than for a fluorescent lamp. Thus，for the two LED sources，the LED with R/B = 4.3 was more suitable for growth of E. aureum.［Ch，4 fig. 2 tab. 13 ref.］
