摘要从甜菜簇的水提取物中获得发芽抑制剂存在的证据。水芹种子的萌发与20个甜菜植株的水提取物的集群和来自相同植物的其他集群的萌发特性之间呈正相关。因此，抑制更大的集群与穷人，而不是良好的发芽提取物，也在未成熟的集群或那些已收到架空灌溉提取物。抑制作用被发现位于花被和果皮组织，而不是在真正的种子。
Summary Evidence was obtained for the presence of germination inhibitors in the aqueous extract from sugar-beet clusters. A positive correlation was shown between the germination of cress seeds moistened with aqueous extracts from clusters of twenty sugarbeet plants and the germination characteristics of other clusters from the same plants. Inhibition was thus greater in extracts from clusters with poor rather than good germination, and also in extracts from immature clusters or those which had received overhead irrigation. The inhibitory effect was found to be located in the perianth and pericarp tissue rather than in the true seed.
