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.
