Abstract:
Hydrangea paniculata Sieb. was cultivated in hydroponics,in which Pb(NO3)2 was in different concentrations that were 0 mg?L-1,50 mg?L-1,100 mg?L-1,150 mg?L-1,200 mg?L-1,respectively,and the growth and physiological index were measured in 5 days,10 days,15 days,20 days,25 days.The results showed that the treatment of 50 mg?L-1 Pb(NO3)2 had higher value in leaf number,relative biomass,plant height,root length,relative growth rate (RGR),net assimilation rate (NAR),biomass (DB) as well as the content of chlorophyll and carotenoid than those of CK,respectively.The content of malondialdehyde (MDA),proline (Pro),as well as the activity of peroxidase (POD) and superoxide enzyme (SOD) were no significance of CK.Lead stress injury symptom survey indicated that the lead patience threshold was application of Pb(NO3)2 up to concentrations of 150 mg?L-1,more than which the relative growth rate (RGR),net assimilation rate (NAR) and biomass (DB) were reduced significantly over 25 days post period when lead concentration increased,and the chlorophyll and carotenoid content decreased with the extension of processing time and had more reduce,but malondialdehyde(MDA),proline (Pro) concentration accumulating increased,peroxidase (POD) and superoxide disproportionation enzyme (SOD) activity increased,respectively.Hydrangea paniculata Sieb.had strongly resistance to lead,for which could be used for soil remediation in lead tailings and phytoremediation in lead-contaminated soil areas.
