Abstract:The effects of Stellera chamaejasme seeds on germination of 6 plants seeds (Stipa copillata,Aneurolepidiumchinense,Elymus dahuricus,Agropyron cristatum ,lepidium apetalum ,Saussurea runcinata,Stellera chamaejasme) were studied with filter paper culture method.The seed densities of Stellera chamaejasmewere 0,5,10,20,40 grains/dish and seed density of 6 grassland plants was 10 grains/dish.The resultsshowed that,the germination rate,germination potential and germination index of the tested seeds increased andthen decreased along with the increasing of seed density of Stellera chamaejasme.When the seed density ofStellera chamaejasme was 10 grains/dish,the promoting effect reached the maximum.The order of effect ofStellera chamaejasme on 6 plants was Elymus dahuricus,Aneurolepidium chinense,Agropyron cristatum ,Stipa copillata ,Saussurea runcinata and Lepidium apetalum .The root length of Saussurea runcinata wasslightly inhibited when the seed density of Stellera chamaejasme was 10 grains/dish,and for the rest 5 testedplants,it was promoted at different degrees.
