has become an increasing weed problem in winter cereals in Northern Europe. However, the information about and its behavior as an arable weed is limited. Field and greenhouse experiments were conducted in 2017/18 and 2018/19, at the Department of Agroecology in Flakkebjerg, Denmark to investigate the emergence, phenological development and growth characteristics of in monoculture and in mixture with winter wheat, in comparison to , and . emerged earlier than and but later than Significant differences in phenological development were recorded among the species. Overall phenology of was more similar to that of than to and . started seed shedding earlier and but later than . was more sensitive to winter wheat competition in terms of biomass production and fecundity than the other species. Using a target-neighborhood design, responses of and to the increasing density of winter wheat were quantified. At early growth stages "BBCH 26-29", was suppressed less than by winter wheat, while opposite responses were seen at later growth stages "BBCH 39-47" and "BBCH 81-90". No significant differences in fecundity characteristics were observed between the two species in response to increasing winter wheat density. The information on the behavior of gathered by the current study can support the development of effective integrated weed management strategies for .
在北欧的冬季谷物中，它已成为一个日益严重的杂草问题。然而，关于它作为一种农田杂草的信息及其行为是有限的。2017/18年和2018/19年，在丹麦弗拉克伯格的农业生态系进行了田间和温室试验，以研究其在单作以及与冬小麦混作时的出苗、物候发育和生长特性，并与[其他物种名称]、[其他物种名称]和[其他物种名称]进行比较。[该物种名称]比[其他物种名称]和[其他物种名称]出苗早，但比[其他物种名称]晚。各物种在物候发育上存在显著差异。[该物种名称]的总体物候与[其他物种名称]的更相似，而与[其他物种名称]和[其他物种名称]的不同。[该物种名称]比[其他物种名称]和[其他物种名称]更早开始种子脱落，但比[其他物种名称]晚。在生物量生产和繁殖力方面，[该物种名称]比其他物种对冬小麦竞争更敏感。采用目标邻域设计，量化了[该物种名称]和[其他物种名称]对冬小麦密度增加的响应。在生长早期阶段“BBCH 26 - 29”，[该物种名称]受冬小麦的抑制小于[其他物种名称]，而在后期生长阶段“BBCH 39 - 47”和“BBCH 81 - 90”则观察到相反的响应。随着冬小麦密度增加，这两个物种在繁殖力特征上未观察到显著差异。本研究收集的关于[该物种名称]行为的信息可为制定有效的[该物种名称]综合杂草管理策略提供支持。
