摘　　要：为研究赤霉素与高温催芽处理对甘薯块根萌芽性的影响,采用酿热物温床育苗,研究不同浓度赤霉素、高温催芽处理、赤霉素结合高温催芽处理对甘薯块根萌芽性的影响。结果表明,随着赤霉素处理浓度的增加,2个品种的采苗数量呈先增加后下降的趋势。低浓度赤霉素对薯块采苗数的影响逐步显现,高温催芽处理条件下,品种间虽存在一定的差异,但2个品种采苗数显著增加,赤霉素组合高温催芽处理显著高于其他处理和对照,但高温催芽更有利于增加块根的发芽量。In order to study the effects of gibberellin and high temperature germination treatment on the germination of Dioscorea esculenta (Lour.) Burkill tuber roots, we studied the effects of different concentration of gibberellin, high temperature germination treatment, gibberellin combined with high temperature germination treatment on the germination of D. esculenta tuber roots. The results showed that with the increase of gibberellin concentration, the number of picking seedlings of the two varieties increased first and then decreased. Low concentration of gibberellin gradually showed the emergence of D. esculenta tubers. Although there were some differences between cultivars under high temperature germination treatment, the emergence of two cultivars increased significantly. The combination of gibberellin and high temperature germination treatment was significantly higher than other treatments and controls, but high temperature germination treatment was more conducive to increase the germination of tubers.
