- 摘要:
- 以堆心菊（Heleniun autumnale）和松果菊（Echinacea purpurea Moench）为试材，比较单种与混种后种子发芽和幼苗生长的各项生理指标。结果表明：混播抑制堆心菊种子萌发，促进松果菊种子萌发；混种的堆心菊幼苗地上鲜质量、根鲜质量和叶面积显著或极显著高于单种，分别是其1.96、2.02、1.75倍；混种的松果菊叶面积显著低于单种；混种的堆心菊根系活力显著高于单种，是其1.24倍；混种与单种的色素含量差异不显著。综合各项指标,2种植物混播时有利于松果菊种子的萌发；幼苗混种时，堆心菊更具竞争优势。
- 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.
