Abstract：
The aim of this study was to examine the effect of the modified light spectrum of glass containing red luminophore on the performance of the photosynthetic apparatus of two types of lettuce cultivated in soil in a greenhouse. Butterhead and iceberg lettuce were cultivated in two types of greenhouses: (1) covered with transparent glass (control) and (2) covered with glass containing red luminophore (red). After 4 weeks of culture, structural and functional changes in the photosynthetic apparatus were examined. The presented study indicated that the red luminophore used changed the sunlight spectrum, providing an adequate blue:red light ratio, while decreasing the red:far-red radiation ratio. In such light conditions, changes in the efficiency parameters of the photosynthetic apparatus, modifications in the chloroplast ultrastructure, and altered proportions of structural proteins forming the photosynthetic apparatus were observed. These changes led to a decrease of CO2 carboxylation efficiency in both examined lettuce types.
摘要：
这项研究的目的是研究含有红色发光体的玻璃的改性光谱对温室土壤中种植的两种生菜的光合装置性能的影响。Butterhead和卷心莴苣在两种类型的温室中种植：（1）用透明玻璃覆盖（对照）和（2）用含有红色发光体（红色）的玻璃覆盖。培养4周后,研究了光合装置的结构和功能变化。这项研究表明，使用的红色发光体改变了阳光光谱，提供足够的蓝光：红光比，同时降低红色：远红辐射比。在这样的光照条件下,光合装置效率参数的变化，叶绿体超微结构的改变，并观察到形成光合装置的结构蛋白的比例改变。这些变化导致两种检查的莴苣类型的CO2羧化效率降低。
