摘要: 本文对崂山地区野生玉竹种子萌发特性进行了研究,结果表明:玉竹种子萌发的适宜温度为20℃、20℃/25℃和25℃;避光处理对种子萌发有较明显促进作用;在35-40℃温水中浸种18-24h有利于种子萌发,发芽率为86.7%。

Abstract: Germinate characteristic property of wild Polygonatum odoratum in Laoshan Mountain area were studied in this paper. The optimum germination temperature was alternating temperatures at 20℃/25℃℃ and constant temperature at 20℃ or 25℃;Dark treatment had obviously effect on germination;the best seed soaking conditions of Polygonatum odoratum was 18-24 hours in 35-40℃ warm waters.
