Ostinata) 提供光合作用所需之光量，並以開發之模型來分析各光譜波段對其鮮重增加之影響。以八種光譜下萵苣栽種之結果，使用所開發之模型，進行傳統三段光譜 (400~500紅光、500~600 綠光與600~700 nm 藍光) 與五段光譜 (400 ~ 475藍光、475 ~ 525藍綠光、525~575綠光、575~625黃橙與625~700 nm紅光) 之分析與比較，以釐清不同光譜波段對波士頓萵苣鮮重增加的貢獻度，與綠、藍光比例對於萵苣生長之影響。<br> Abstract: Light is the basis of plant photosynthesis. Researches in analyzing the influence of photosynthesis active radiation (400-700 nm) on the impact of the crops divided into three kinds of light wavelength: blue (400 ~ 500 nm), green (500 ~ 600 nm) and red (600 ~ 700 nm) light. Analysis errors happen due to the wide range of the light wavelength, especially there are some controversies on green light impact of the plant. For example, some research seems that green light is beneficial to the crops growing, but some are on the opposite site or shows that green light is not necessary to the crops growing. This study aimed to clarify the effects of fresh weight on hydroponic Lactuca sativa in different bands of light. This study use a different spectrum fluorescent tube (T5) and seven kinds of LED lamps (T-A, T-Y, T-N, T-M, E-CW, G-CW and E-WW) to provide the light quantum of photosynthesis on indoor hydroponic Lactuca sativa (Lactuca sativa L. cv. Ostinata) and built the model. Afterwards, we analyzed the influence of fresh weight increases in various spectral bands by the model. We used the model to analyze and compare the results of eight spectral light of lettuce growth, the traditional three sections of spectrum (400 to 500 nm of red, 500 ~ 600 nm of green, and 600 ~ 700 nm of blue) and five sections of spectrum (400 to 475 nm of blue, 475 to 525 nm of blue-green, 525 ~ 575 nm of green, 575 ~ 625 nm of yellow-orange, and 625 ~ 700 nm of red). We supposed to clarify the contribution of different spectral bands on Lactuca sativa fresh weight increase and the influence of lettuce growth in green and blue light proportion.植物照明光質模型分析波士頓萵苣horticulture lightinglight qualitymodel analysisBoston lettuce
