使用小麦胚芽鞘直接生长测试，测定了甜菜品种春化（开花）和非春化（非开花）植物叶片中生长调节物质水平的变化。Poly-AG-波兰在2个阶段;春化处理结束（从种植开始210天）和盛花期。从种植210天后，仅在非春化植物的叶提取物中检测到IAA。没有检测到抑制活性，除了在非春化植物的叶的浓缩提取物的情况下。在冷处理后和开花时的开花植物的叶片中，在Rf 0.5-0.8处发现该生长促进区。这一生长促进作用区被认为在甜菜开花中起主要作用。
The changes in the levels of growth regulating substances using the wheat coleoptile straight growth test were determined in the leaves of vernalized (flowering) and non-vernalized (non-flowering) plants of sugar-beet cv. Poly-AG-Poland at 2 stages; the end of vernalization treatment (210 days from planting) and full-flowering stage. IAA was detected only in the extracts of the leaves of non-vernalized plants after 210 days from planting. No inhibitory activity was detected, except in the case of the concentrated extract of the leaves of non-vernalized plants. This growth promoting zone was found at Rf 0.5-0.8 in the leaves of flowering plants after cold treatment and at flowering time. This zone of growth promoting action was suggested to have a major role in the flowering of sugar-beet.
