摘要: 将36个普通小麦品种的完整穗卷在纸巾里做发芽试验,测定了穗发芽度和穗发芽率,并在皮氏培养皿里测定了22个品种的种子休眠性。在本研究中,腊熟期种子休眠的白粒地方品种"宜宾白麦子"最抗穗发芽。讨论了影响穗发芽的其它因素。

Abstract: Degree and percentage of sprouting in 36 common wheat varieties were measured in a gremination test with intact spikes rolled in paper towels, Seed dormancy in 22 varieties was tested by means of threshed seeds in petri dishes. White native variety "Yibin Baimaizi" with dormancy at wax ripeness was the most resistant to sprouting in this study. Other factors restricting preharvest sprouting are also discussed.
