Cultivated northern wild rice (NWR), Zizania palustris L., is an aquatic grass native to North America that is grown in paddies and harvested for its grain. Domestication of the species began in Minnesota in the early 1950s to provide a stable source of the grain for food processors and to utilise marginal agricultural land. The University of Minnesota has been conducting breeding research on NWR since the 1960s. However, a detailed description of the species phenological stages has not been documented, which would help to standardise results across studies, aid in building accurate crop models, and improve the efficacy of time‐sensitive crop management practices. We present here a phenological scale of cultivated NWR based on the widely adopted Biologische Bundesantalt, Bundessortenamt and Chemische Industrie (BBCH) scale, a system for a uniform coding of phenologically similar stages in plant species' (Bleiholder et al., Gesunde Pflanzen, 1989, 41, 381–384; Meier et al., Nachrichtenblatt des Deutschen Pflanzenschutzdienstes (Braunschweig), 1993, 45(2), 37–41). Data were collected in lab, greenhouse, and field settings at the North Central Research and Outreach Center at the University of Minnesota in Grand Rapids, MN. Ten principal and secondary phenological stages are described using the two‐digit BBCH coding system. The description and coding of the scale covers the principal periods from seed storage to seed harvest.

BBCH量表确定的北方野生稻栽培期的物候阶段

栽培北方野生稻(NWR),Zizania palustrisL.,是一种北美原产的水生草,生长在稻田中并收获其谷物。该物种的驯化始于1950年代初在明尼苏达州,为食品加工者提供稳定的谷物来源并利用边缘农业土地。明尼苏达大学自1960年代以来一直在进行NWR的育种研究。但是,尚未记录有关物种物候阶段的详细描述,这将有助于标准化研究结果,帮助建立准确的作物模型并提高对时间敏感的作物管理实践的有效性。我们在此介绍了基于广泛采用的Biologische Bundesantalt,Bundessortenamt和Chemische Industrie(BBCH)量表的栽培NWR的物候量表,一个统一编码植物物种物候相似阶段的系统(Bleiholder等,Gesunde Pflanzen,1989,41,381–384; Meier等,Nachrichtenblatt des Deutschen Pflanzenschutzdienstes(Braunschweig),1993,45(2) ,37-41)。数据是在明尼苏达州大急流城的明尼苏达大学北部中央研究与推广中心的实验室,温室和田野环境中收集的。使用两位BBCH编码系统描述了十个主要和次要物候阶段。量表的描述和编码涵盖了从种子储存到种子收获的主要时期。和田野设置,位于明尼苏达州大急流城的明尼苏达大学北部中央研究与推广中心。使用两位BBCH编码系统描述了十个主要和次要物候阶段。量表的描述和编码涵盖了从种子储存到种子收获的主要时期。和田野设置,位于明尼苏达州大急流城的明尼苏达大学北部中央研究与推广中心。使用两位BBCH编码系统描述了十个主要和次要物候阶段。量表的描述和编码涵盖了从种子储存到种子收获的主要时期。
