摘要
以2种朱槿为试材,研究了UV-B辐射对朱槿过氧化物酶(POD)活性、可溶性糖、可溶性蛋白质、叶绿素、总黄酮类物质含量等生理生化指标的影响。结果表明在UV-B辐射胁迫下,2种朱槿叶片的生理生化指标均发生明显的变化,七彩朱槿具有较强的抗UV-B辐射能力。
Two Hibiscus rosa-sinensis were used to study the effects of ultraviolet-B radiatiion on the physiclogy and biochemistry of Hibiscus.Such as POD activity,the content of soluble saccharin,soluble protein,chlorophyll and total flavoniods.The results showed that under the UV stress,physiclogical and biochemincal indexes in the leaves of two Hibiscus both produced marked changes;the H.rosa-sinensis＇Cooperi＇had strong ability of antiultraviolet-B radiation.
