研究光质对金线莲形态特征、叶片解剖特征、抗氧化酶（超氧化物歧化酶、过氧化氢酶和过氧化物酶）活性、光合色素含量和生物活性物质（酚类、黄酮类和多糖类）含量的影响。植物A.将刺梨在通过四种不同颜色的膜过滤的光下生长8个月。4个处理分别为红膜（RF）、蓝膜（BF）、黄膜（YF）和无色塑料膜（CK）。与A. BF处理的茎粗、鲜重、叶面积、气孔频率、叶绿素含量（Chl a、Chl B、Chl a+B）、抗氧化酶活性和活性物质（多糖、黄酮）含量均显著高于对照。RF处理的植株表现出最大的株高和酚类物质含量。这些结果表明，生长的A.蓝膜栽培是提高刺梨品质的有效技术措施。该技术有助于实现高质量植物材料的大规模可持续生产。
The aim of this study was to investigate the effects of light quality on the morphological traits, leaf anatomical characteristics, antioxidant enzyme (superoxide dismutase, catalase, and peroxidase) activities, photosynthetic pigments content, and bioactive compounds (phenols, flavonoids, and polysaccharides) content in Anoectochilus roxburghii. Plants of A. roxburghii were grown under light filtered through four differently colored films for 8 months. The four treatments were red film (RF), blue film (BF), yellow film (YF), and colorless plastic film (control, CK). Compared with the A. roxburghii plants in CK, those in the BF treatment showed significantly greater stem diameter, fresh weight, leaf area, stomatal frequency, chlorophyll content (Chl a, Chl b, Chl a+b), antioxidant enzyme activities, and active compound (polysaccharides, flavones) content. The plants in the RF treatment showed the greatest plant height and phenolics contents. These results show that growing A. roxburghii plants under blue film is a useful technique to improve quality. This technique is conducive to achieving large-scale sustainable production of high-quality plant materials.
