Changes of Physiological Characters of Wheat After Water-logging at Booting and Relations Between Ph

<正> Effects of waterlogging on some physiological characters and relationship between waterlogging tolerance and some characters of their own were studied by using 12 varieties of wheat. Results showed waterlogging made the content of malondialdehyde in flag leaf increase, made the root vigor, the content of chlorophyll, the net photosynthesis rate, the nitrate reductase activity, the relative water content of flag leaf decrease, the content of organic matter change obviously, and then the yield per plant declined. The correlations
