UNASSIGNED: In a large-scale container experiment, three different oat varieties were cultivated and exposed to 14 consecutive days of waterlogging stress at two developmental stages.
UNASSIGNED: Even though vegetative growth was impaired after early waterlogging and which persists till maturity, mainly due to transient nutrient deficiencies, growth performance after late waterlogging and grain yield of all three oat varieties at maturity was not affected. A high tolerance was also confirmed after late waterlogging in the beginning generative stage: grain yield was even increased.
UNASSIGNED: Overall, all oat varieties performed well under both stress treatments, even though transient nutrient imbalances occurred, but which were ineffective on grain yield. Based on these results, we conclude that oats, independently of the cultivar, should be considered a good alternative in crop production, especially when waterlogging is to be expected during the cultivation phase.
■在大型容器实验中,栽培了三个不同的燕麦品种,并在两个发育阶段连续暴露于14天的淹水胁迫中。
■即使在早期淹水后营养生长受损并持续到成熟,主要是由于短暂的营养缺乏,晚涝后的生长性能和成熟时所有三个燕麦品种的籽粒产量均未受到影响。在开始的生成阶段晚涝后,也证实了高耐受性:谷物产量甚至增加。
■总的来说,所有燕麦品种在两种胁迫处理下表现良好,即使发生了短暂的营养失衡,但对谷物产量无效。基于这些结果,我们得出的结论是燕麦,独立于品种,应该被认为是作物生产的一个很好的选择,特别是在种植阶段预计会出现内涝时。
