摘要:
 为了解白蜡、枫杨和黄连木3树种在涝渍条件下的适应性,通过模拟田间涝渍胁迫,研究1年生实生苗在对照CK、渍处理T1处理、涝处理T2处理,处理时间60 d 3种不同土壤水分胁迫下的生长与生理状况。结果表明,3树种的抗涝能力为白蜡>枫杨>黄连木,在涝渍处理下还原性谷胱甘肽(GSH)、超氧化物歧化酶(SOD)、抗坏血酸(ASA)和抗坏血酸过氧化物酶(ASA-POD)活性较对照有明显上升,随胁迫程度的加重和时间的延长,呈先上升后稳定的趋势,黄连木呈现出下降的趋势。白蜡和枫杨具有较好的耐水能力,黄连木耐水能力较差。
Abstract:
 In order to understand adaptability of Fraxinus chinensis,Pterocarya stenoptera and Pistacia chinensis to waterlogging,the growth status and photosynthesis of 1-year-old seedlings were investigated in a 60-day waterlogging experiment.The results showed the waterlogging resistance of the 3 species was in the order of F.chinensis>P.stenoptera>P.chinensis.F.chinensis and P.stenoptera showed perfect tolerance to waterlogging or flooding.Under the waterlogging and flooding stress,superoxide dismutase (SOD) activity,ascorbic acid-ascorbic acid peroxidase (ASA-POD) activity,ascorbic acid (ASA) content and reductant glutathione (GSH) content in the leaves or roots showed significant rise and tended to be stable.P.chinensis showed a downward trend.In summary,F.chinensis and P.stenoptera showed better ability tolerant to waterlogging or flooding than P.chinensis.
