Abstract: The effects of storage temperature on vigor and anti-lipid-peroxidation of ultradried seeds of Pugionium Gaertn. were studied by reducing the moisture content of Pugionium cornutum（L.）Gaertn. and Pugionium dolabratum Maxim to 3.1%，2.2%，1.3% from the initial content respectively by silica gel，and aged at 50 ℃，35 ℃ and 20 ℃ for 1 year，which would provide theoretical basis for aging and storage of the seeds. The results indicated that there were optimum moisture content of P. cornutum（L.）Gaertn. and P. dolabratum Maxim. seeds stored at 50 ℃，35 ℃ and 20 ℃，and the contents of P. cornutum（L.）Gaertn. and P. dolabratum Maxim. seeds increased from 4.5%–3.1% and 4.3%–2.2% to 4.5%–2.2% and 4.3%–1.3% with the declining of the temperature respectively. The deterioration of the seed vigor occurred earlier than germination percentagereduction significantly. After aging treatment，relative electrical conductivity of the seeds increased when the content decreased，and seed germination，vigor and the integrity of cell membranes of the seeds with initial moisture content（CK）were the best in all ultradried seeds. The range of optimum moisture contents and the ability of resisting aging ofP. dolabratum Maxim. seeds were greater than P. cornutum（L.）Gaertn. seeds. The generation of superoxide generation rate（）and accumulation of malondialdehyde（MDA）were promoted in storage process，and the influence was the lowest at 35 ℃. The activities of CAT，GPX，APX of the two specie seeds were still retained，which affected by stored temperature. Under the experimental conditions，the optimal conditions of storage were suggested that the optimum moisture content of P. cornutum（L.）Gaertn. and P. dolabratum Maxim. seeds are 4.5% and 4.3% respectively at 35 ℃.
