The effects of selenite (0, 15, 30, 45 mg L) on physiological characteristics and medicinal components of were analyzed. The results showed that selenite application promoted the activity of superoxide dismutase and the contents of soluble sugar, proline, carotenoids, total flavonoids, and total polyphenols, and decreased the contents of reactive oxygen species, relative electrical conductivity, and malondialdehyde. In addition, selenite also increased chlorophyll content, improved electron transfer ability, PSI and PSII performance, and the coordination between PSI and PSII, which significantly improved photosynthetic capacity. Moreover, selenite treatment also greatly increased the contents of gallic acid, catechin, albiflorin, paeoniflorin, benzoic acid, and paeonol in Moutan cortex radicis (MCR). These results showed that selenite effectively protected the photosynthetic apparatus from photooxidative damage by enhancing antioxidant capacity, improving photosynthetic capacity, and increasing the content of the medicinal compounds in MCR.
分析了亚硒酸盐（0、15、30、45毫克/升）对[具体植物名称未给出]生理特性和药用成分的影响。结果表明，施用亚硒酸盐可促进超氧化物歧化酶的活性以及可溶性糖、脯氨酸、类胡萝卜素、总黄酮和总多酚的含量，并降低活性氧、相对电导率和丙二醛的含量。此外，亚硒酸盐还增加了叶绿素含量，提高了电子传递能力、光系统I和光系统II的性能以及光系统I和光系统II之间的协调性，从而显著提高了光合能力。而且，亚硒酸盐处理还极大地增加了牡丹皮中没食子酸、儿茶素、白花芍药苷、芍药苷、苯甲酸和丹皮酚的含量。这些结果表明，亚硒酸盐通过增强抗氧化能力、提高光合能力以及增加牡丹皮中药用化合物的含量，有效地保护了光合机构免受光氧化损伤。
