在增强紫外线辐射条件下,研究喷施芦荟蒽醌类物质对大豆叶形态结构和生理生化指标的影响,旨在探究增强UV-B辐射条件下芦荟蒽醌物质对植物的保护作用。研究结果表明,在增强UV-B辐射条件下,大豆株高降低、叶面积明显减小、光合色素含量下降、丙二醛含量升高;喷施芦荟蒽醌物质能有效缓解叶绿素含量、生物量降低,减少丙二醛产生;在增强UV-B辐射条件下,叶细胞表面蜡状物质增加明显,气孔明显下陷;而喷施芦荟蒽醌物质后,表面蜡状物质仅稍有增加,气孔下陷状况有所缓解。
Under the condition of enhanced UV radiation, the effects of spraying anthraquinones from Aloe vera on the morphological and physiological and biochemical indexes of soybean leaves were studied in order to explore the protective effect of anthraquinones from aloe on the plants under enhanced UV-B radiation. The results showed that plant height decreased, leaf area decreased, photosynthetic pigment content decreased, and malondialdehyde content increased under enhanced UV-B radiation. Anthraquinone sprayed aloe can effectively alleviate chlorophyll content, biomass Reduce and reduce the production of malondialdehyde. Under the condition of enhanced UV-B radiation, the waxy substance on the leaf cells increased obviously and the stomata obviously subsided. After the anthraquinone substance was sprayed on the surface of aloe, the surface waxy substance only slightly increased, The situation eased.
