摘　　要：采用不同浓度赤霉素(100、200、500 mg/L)经不同处理时间(1、5 h)后培养在不同温度(20、25℃)下,探讨对两头毛种子萌发和幼苗生长的影响。结果表明,培养温度在20℃,赤霉素浓度在100~500 mg/L处理1 h时两头毛的种子萌发均与对照组呈显著差异。而培养温度在25℃,赤霉素处理(不同浓度和处理时间)均显著提高两头毛幼苗的株高。这些研究结果可为将来人工栽培两头毛优化播种育苗技术提供依据。Different concentrations of gibberellin(100, 200, 500 mg/L) were used for different treatment times(1, 5 h) and cultured at different temperatures(20, 25 ℃) to explore the effects on seed germination and seedling growth of Incarvillea arguta.The results showed that when the culture temperature was 20 ℃ and the gibberellin concentration was 100-500 mg/L for 1 h, the seed germination of Incarvillea arguta was significantly different from that of the control group.While the cultivation temperature was 25 ℃, gibberellin treatment(different concentrations and treatment time) significantly increased the plant height of Incarvillea arguta seedlings.These results will provide the basis on the artificial seedling-raising of Incarvillea arguta.
