红三叶草的特殊结构特征与良好再生的相关性尚未阐明。在这里，我们提出了拍摄架构和再生的六个红三叶草基因型控制和田间条件下分析，有和没有竞争多年生黑麦草。在所调查的基因型中，Lemmon和Crossway表现出最高的节数和分枝数，基部7 cm的节数增加最多，该区域的节的生长能力最高，导致干物质产量最高。我们的研究结果表明，选择基因型与高数量的一级分支，短节间和恢复生长的能力，从节点，保持在未切割区将允许发展的品种具有良好的再生。
The relevance of particular architectural characteristics for a good regrowth has not been elucidated yet in red clover. Here, we present the shoot architecture and regrowth of six red clover genotypes analysed under controlled and field conditions, with and without competition from perennial ryegrass. Among the genotypes investigated, Lemmon and Crossway displayed the highest number of nodes and branches, the highest increase in the number of nodes in the basal 7 cm and the highest outgrowth capacity of the nodes in this zone resulting in the highest dry-matter yields. Our results indicate that selecting genotypes with a high number of first-order branches, short internodes and the ability to resume growth from the nodes that remain in the uncut zone will allow the development of cultivars with good regrowth.
