摘要: 以二年生金叶冬青(Ilex cornuta ‘Oigon’)扦插苗为试材,盆栽模拟淹水胁迫,对金叶冬青叶片形态及生理生化指标进行研究。结果表明,淹水对金叶冬青的叶色和生理生化指标的影响较为明显。随淹水胁迫时间的延长,金叶冬青叶片的颜色变暗;叶绿素的含量处于平缓、略增加的状态;叶片的初始荧光Fo明显下降,最大荧光Fm、PSⅡ最大光化学效率Fv/Fm、PSⅡ潜在光化学活性Fv/Fo均呈明显降低的趋势;可溶性糖、可溶性蛋白质和丙二醛的含量逐渐上升。淹水180 d后,成活率为20%,说明金叶冬青对淹水的适应能力较强。

Abstract: The morphological, physiological and biochemical indexes of two-year-old Ilex cornuta ‘Oigon’ cuttings were studied by pot experiments under simulated flooding stress. The results showed that the effects of water flooding on leaf color and physiological and biochemical indexes were obvious. With the prolongation of water flooding time, the color of its leaves became dark, and the content of chlorophyll was in a mild and slightly increased state. The initial fluorescence Fo of leaves decreased obviously, and the maximum fluorescence Fm, PSII maximum photochemical efficiency Fv/Fm, PSII potential photochemical activity Fv/Fo decreased obviously. The content of soluble sugar, soluble protein and MDA increased gradually. After 180 days of water flooding, the germination rate was 20%. It is indicated that the adaptability of it to water flooding is stronger.

Key words: water flooding, Ilex cornuta ‘Oigon’, chromatic aberration, physiological and biochemical indexes
