摘要: 为了揭示烯效唑对向日葵生长的调控效应,试验采用高产、高秆食用向日葵品种SH361为材料,设置不同浓度烯效唑浸种和叶面喷施的处理。结果表明:烯效唑浸种处理后,向日葵株高和茎粗降低,叶柄长度缩短,叶面积缩小,浓度为230 mg/L处理株高比对照降低37.7%;开花期单株绿叶面积缩小最明显,比对照缩小44.55%。叶面喷施处理后,株高无明显降低,茎粗增加,叶柄长度增加,叶面积增大。茎粗和叶柄长以浓度为400 mg/L处理增加效果最明显,分别比对照增加17.02%和5.57%。烯效唑浸种和叶面喷施均可增加叶绿素SPAD值。浓度为230 mg/L浸种处理生长指标降低,400 mg/L叶面喷施处理后向日葵生长指标增加最明显。

Abstract: In order to reveal the regulation effect of the uniconazole on sunflower growth,using a high yield,high quality, and stalk feed varieties SH361 as materials,we set different uniconazole concentration treatments of seed soaking and leaf spraying. The results showed that, after soaking seed with a concentration of 230 mg/L uniconazole, the sunflower plant height and stem diameter decreased with the plant height being 37.7% lower than the control,the petiole had shorter length,and the leaf area in the flowering period was inhibited significantly by 44.55% compared with the control. After leaf spraying,the plant height did not decrease,while the stem diameter,the petiole length, and the leaf area increased. Compared with the control, the stem diameter and petiole length with a concentration of 400 mg/L were increased by 17.02% and 5.57%,respectively. The chlorophyll SPAD value was increased by seed soaking and leaf spraying. The results showed that seed soaking with 230 mg/L decreased the growth index and leaf spraying with 400 mg/L uniconazole increased the sunflower growth index significantly.
