摘要: 以冬青(Ilex chinensis)、大别山冬青(I.dabeishannensis)、‘兰少女’冬青(I.×meserveae ‘Blue Girl’)和‘金宝石’冬青(I.crenata ‘Golden Gem’)3年生苗木为材料,经苯胁迫处理后,用透射电子显微镜观察叶肉细胞超微结构的变化。结果表明:苯气体胁迫处理后4种冬青叶肉细胞的细胞膜系统、叶绿体、细胞核等结构都受到不同程度的破坏。4种冬青对苯气体胁迫的抗性从强到弱依次为:大别山冬青、‘兰少女’冬青、‘金宝石’冬青和冬青。

Abstract: In this paper, 3 year old seedlings of four types of Ilexs, Ilex chinensis, I.dabeishannensis, I.×meserveae ‘Blue Girl’ and I.crenata ‘Golden Gem’ were treated with benzene stress. After the treatment, the ultrastructure changes of their mesophyll cells were observed under the transmission electron microscope. The results showed that: for all the tested samples, their membrance systems, organelle structure stabilities and nucleus structures were damaged at different degree after the benzene stress and their fastness in resisting benzene stress were sorted as I.dabeishannensis﹥I.×meserveae ‘Blue Girl’﹥I.crenata ‘Golden Gem’﹥Ilex chinensis.
