Knotweed (Reynoutria sp.) plants are known in the world mainly as invasive plants. However, it is known that their rhizomes or leaves contain secondary metabolites with biological activity. Our goal was to determine which of the three knotweed plants (Reynoutria japonica, Reynoutria × bohemica, and Reynoutria sachalinensis) is most suitable for seed growth stimulation. We tested alcoholic extracts of all three knotweed species by seed priming method on wheat germination and seedling characteristics, when 12 measured characteristics were monitored. Extracts from all three species of Reynoutria sp. generally showed an improvement in wheat germination and growth compared to the control. R. × bohemica appears to be the best source for stimulating wheat growth, as seedling vigor indexes I and II, R/S dry weight, shoot and seedling lengths, root, shoot, and seedling dry weights were significantly different (ANOVA, Duncan's test, α < 0.05). The plants Reynoutria spp. seem to be possible sources for the protection and stimulation of agriculture crops.
蛇莓（Reynoutria sp.）植物在世界范围内主要被认为是入侵植物。然而，人们已经知道，它们的根茎或叶子含有具有生物活性的次生代谢物。我们的目标是确定三种蛇莓植物（日本蛇莓、杂交蛇莓和朝鲜蛇莓）中哪一种最适合刺激种子生长。我们通过种子引发法，用三种蛇莓属植物的醇提物处理小麦种子，监测了 12 个测量特征。与对照相比，来自三种 Reynoutria sp.的提取物通常显示出对小麦发芽和生长的改善。R. × bohemica 似乎是刺激小麦生长的最佳来源，因为幼苗活力指数 I 和 II、R/S 干重、茎和幼苗长度、根、茎和幼苗干重均有显著差异（ANOVA，Duncan 检验，α<0.05）。蛇莓属植物似乎是保护和刺激农业作物的潜在来源。
