目的: 采用烯效唑浸种方法探讨不同浸种浓度对不同品种燕麦生长发育的影响。方法: 本实验以晋莜8号、鉴Ⅲ1618、XHY-1为研究对象,分别用0、15、30和45 mg·L-1烯效唑对燕麦种子浸种处理,研究其对不同燕麦品种幼苗形态指标和生理指标的影响。结果: 结果表明不同浓度的烯效唑浸种处理对燕麦有“控上促下”作用,增加叶片中叶绿素和脯氨酸含量,降低丙二醛含量,增强抗逆性,促进燕麦产业化发展。晋莜8号、XHY-1在形态指标和生理指标都要显著优于鉴Ⅲ1618,而晋莜8号、XHY-1之间无显著性差异。结论: 结合烯效唑浸种处理方法,在山西燕麦实际生产过程中,推荐选用晋莜8号、XHY-1,烯效唑浸种浓度以15 mg·L-1为宜。

Objective: The effect of different soaking concentrations on the growth and development of different varieties of oats was studied by the soaking method with uniconazole. Methods: The experiment was conducted with different oat seeds including Jinyou 8, Kam Ⅲ 1618 and XHY-1, which were treated with uniconazole with different concentrations(0, 15, 30 and 45 mg·L-1). Results: The results showed that soaking seeds with different concentrations of uniconazole have “astrict the aerial part but promote the underground part” effect of oats, it will promote root growth; increase chlorophyll and proline content of leaf, it also will reduce the content of malondialdehyde and enhance plant stress resistance, promote the industrialization of oats cultivation. The morphological indicators and physiological indicators of Jinyou 8, XHY-1 should be significantly better than KamⅢ 1618, and in this experiment Jinyou8 and XHY-1 have their uique indicator in various treatment with different uniconnazole concentrations. Conclusion: When combining with the method of uniconazole soaking seed treatment, in the actual production of Shanxi oats, it is recommended to use Jinyou 8, XHY-1 in production, and the appropriate soaking concentration of uniconazole is 15 mg·L-1.
