在杭州春夏播条件下,冬春性不同的大麦品种间生长发育差异明显。春化处理效应因品种和播期而异。未抽穗植株幼穗发育的停滞时期有随播期推迟,品种冬性增强而提前的趋势,作者认为生长锥伸长是春化阶段结束的标志的传统说法不够确切。明确了根据分期春播各品种抽穗性的差异,是鉴定大麦品种春、冬性强弱的简单可靠的好方法。本文还讨论了春化处理效应因播期而异的原因,并提出了大麦春化阶段对温度要求的新看法。 Under the conditions of spring and summer seeding in Hangzhou, the differences of growth and development between different winter and spring barley varieties were significant. The effect of vernalization varies by species and sowing date. The stagnant period of panicle development of un-earing plants was delayed with the sowing date, and the varieties tended to increase in winter. The author believes that the traditional statement that the growth cone elongation is the sign of the vernalization stage is not exact enough. It is clear that according to the difference of heading date of different spring varieties, it is a simple and reliable method to identify the strength of spring and winter of barley varieties. The paper also discusses the reason that the vernalization effect varies with sowing date, and puts forward a new view on the temperature requirement during vernalization of barley.
