Abstract:
Cucumber seedlings were used as experimental materials to study the effects of waterlogging stress （0,4,8,12 days) on the growth index and adventitious root anatomy.The results showed that waterlogging inhibited the growth of root fresh weight,stem fresh weight,leaf fresh weight,plant height and the stem diameter （cotyledons up and down 1cm).Under waterlogging stress for 4 days,root fresh weight,stem fresh weight,leaf fresh weight and plant height were restrained significantly;for 8/12 days,stem diameter which cotyledons up/down 1 cm was restrained significantly,respectively.However,under waterlogging stress within 12 days,the leaf number had no significant change.MDA content of leaves was significantly higher than control after 4 days.Under waterlogging stress for 12 days,the adventitious roots of cucumber had a lysigenous aerenchyma,but it was not developed.It showed that the cucumber seedling had enduranced to adapt waterlogging stress,but the ability of endurance was limited.
