- 摘要:
- 以黄山栾树1 a生幼苗为试材，研究了人工模拟淹水胁迫对其生长、光合特性及部分抗氧保护酶活性的影响。结果表明：经过35 d的淹水处理，淹水组的黄山栾树幼苗全部死亡，叶片也全部脱落，淹水处理的黄山栾树幼苗的生长及光合作用均受到较大的抑制；黄山栾树幼苗的相对电导率随叶片淹水处理时间的增加而升高，可溶性蛋白质含量、超氧化物歧化酶（SOD）活性和过氧化物酶(POD)活性均随淹水处理时间的增加总体呈下降趋势。因此认为，黄山栾树并无良好的抗涝能力，属于不耐水湿植物。
- Abstract:
- Taking one-year-old seedlings of Koelreuteria integrifolia?as test material,the effects of waterlogging stress on their growth,photosynthetic characteristics and some antioxidant enzymes’ activity were studied.The results showed that after 35 d waterlogging treatment,all ofKoelreuteria integrifoliaseedlings died,and all of their leaves fell.The growth and photosynthesis of seedlings of Koelreuteria integrifoliawere subject to great inhibition.The relative conductivity of Koelreuteria integrifoliaincreased as the time went by；the activity of soluble protein,SOD activity and POD activity reduced as the waterlogging kept on.Thus,Koelreuteria integrifoliaseedlings do not have a good ability to waterlogging,they belong to wet intolerance plants.
