酸雨在我国南方已成为十分严重的环境问题。本研究中,我们选取了四种在我国南方受酸雨危害严重地区广泛分布的木本植物作为实验材料,分别为枫香(LiquidambarformosanaHance),木荷(SchimasuperbaGardnetChamp.),马尾松(PinusmassonianaLamb.)及红豆杉(Taxuswallichianavar.mairei)。分别研究了土壤中不同钙水平对四种木本植物在应对模拟酸雨(SiAR)胁迫中的各种响应,包括模拟酸雨对植物叶片的伤害、对叶绿素含量、叶片净光合速率的影响,特别是钙受体(CAS)的蛋白及基因相对表达水平等。采用Western-blot技术...Acid rain (AR) has been a serious environmental problem in southern China. Four selected tree species, Liquidambar formosana Hance, Schima superba Gardn et Champ, Pinus massoniana Lamb and Taxus wallichiana var. mairei are widely distributed in southern China, where acid deposition is becoming more and more serious. In this study, we investigated the differential responses to simulated AR (SiAR) a...学位:理学硕士院系专业:生命科学学院_植物学学号:2162010115247
