摘要
为探讨野生大豆(Glycine soja)种子萌发与温度的关系,将浓硫酸浸泡处理和砂磨处理过的种子置温度5、10、15、20、25、30、35℃恒温及25/15℃(昼/夜)变温条件下进行发芽试验,测定各温度下种子发芽率、发芽势及发芽指数.试验结果表明,野生大豆种子的适宜萌发温度为15-30℃,浓硫酸浸泡最佳处理时间为40min.
The effect of temperature treatments on germination of wild soybean(Glycine soja) was studied in the paper.The seeds were soaked in 98% sulfuric acid for 20,30,40,50 and 60 minutes and grinded with sand respectively,then incubated under the condition of 5,10,15,20,25,30,35℃ and 25/15℃(day/night).Seed germination rate,germination index and germination vigour were recorded.The results showed that the optimum germination temperatures of wild soybean ranged from 15 to 30℃,and the treatment time of seed for 40 min in 98% sulfuric acid will be helpful to germination of wild soybean seed
