Abstract:
Seeds of Codonopsis pilosula,Codonopsis pilosula and Codonopsis tangshen were used as test materials,the different concentrations of polyethylene glycol (PEG-6000) were used to simulate degrees of drought stress.The effects of polyethylene glycol (PEG-6000) on seed germination of Codonopsis radix were studied and the response of Codonopsis radix of different varieties to drought stress during germination were inspected.The results showed that the seed germination rate,the germination potential and the germination index were inhibited to different degrees with the increase of polyethylene glycol (PEG-6000) concentration.The lowest concentration threshold of the germination inhibition of seeds of Codonopsis pilosula,Codonopsis tangshen,Codonopsis pilosula was 5%,10% and 15%,respectively.It was suggested that the Codonopsis pilosula had the best drought resistance,Codonopsis tangshen had the middle drought resistance,and the Codonopsis pilosula had the worst drought resistance. Keywords:Codonopsis radix;drought stress;seed germination;concentration threshold;polyethylene glycol (PEG-6000)
