摘要: 通过室内模拟试验,研究了不同强度UV-B辐射(10μW/cm²和20μW/cm²)对仙客来(Cyclamen persicum Mill)生理的影响。结果表明:(1)UV-B辐射的增加对仙客来叶片光合色素的含量具有影响;(2)叶片质膜透性随UV-B辐射强度的增加而增加,随UV-B辐射时间的延长而增加;(3)叶片类黄酮含量随UV-B辐射强度的增加而增加,且在40d时达到最大值;(4)增强UV-B辐射下,仙客来花瓣中的花青素含量增加。

Abstract: Effects of UV-B radiation on physiology of Cyclamen persicum Mill were studied through indoor simulation experiment.The result showed that:(1)Photosynthesis pigments(chlorphyll a,chlorphyll b and carotinoid)contents increased with UV-B radiation,and decreased with the enhanced UV-B radiation prolonged;(2)Membrane permeability of the leaves were increased by UV-B radiation and increased with the enhanced UV-B radiation prolonged;(3)Flavonoid contents of leaves were increased by UV-B radiation,and the highest value of flavonoid contents were showed in UV-B radiation 40 days;(4)Anthocyanin contents in the petals of C.persicum increased under UV-B radiation.
