Abstract:: To compare the physiological indexes of Heleniun autumnale and Echinacea purpurea Moench from seed germination to seedling growth，which were planted by hybrid or single way.The results showed that under the hybrid condition，Heleniun autumnale seed germination was inhibited，while Echinacea purpurea Moench seed germination was promoted.The ground weight，root weight and leaf area of Heleniun autumnale in hybrid were significantly or very significantly higher than single，which were 1.96，2.02,1.75 times.The leaf area of Echinacea purpurea Moench in hybrid was significantly lower than single.The root activity of Heleniun autumnale in hybrid was significantly higher than single，which was 1.24 times.The pigment content of both had no significant change.Comprehensive performance indicators，it was beneficial to seed germination of Echinacea purpurea Moench when both seeds mixture.When hybrid seedlings，Heleniun autumnale had a competitive advantage.
