Abstract
Effects of Cd on leaf length,chlorophyll content,diurnal variation of photosynthesis and proline content of cucum-ber seedlings(JIN YOU 35,Cucumis sativus L.)treated in containers with different concentrations of Cd(0,10,50,100 and500 μmol/L)were investigated in the present study in order to further explore the possible mechanisms of Cd tolerance of C.sativus. The results indicated that:(1)The leaf length of C. sativus in the present investigation was found to be sensitive to Cd. The inhibition increased significantly with increasing concentrations of Cd and duration of time;(2)The chlorophyll content decreased firstly,then increased with increasing concentrations of Cd;(3) Cd inhibited photosynthesis significantly,and the photosynthetic index decreased significantly except for the stomatal limitation value. The diurnal variation of photo-synthesis changed slowly. Under 500 μmol/L Cd stress,C. sativus lost the characteristics of midday depression;(4)Under the stress of Cd,the contents of proline increased with the increase of the concentrations of Cd.
