Abstract

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.

节节草（Reynoutria spp.）叶片的提取物对小麦的发芽和初期生长有促进作用

结缕草（Reynoutria sp.）植物在世界上主要作为入侵植物而闻名。不过，人们知道它们的根茎或叶片含有具有生物活性的次级代谢物。我们的目标是确定三种结缕草植物（Reynoutria japonica、Reynoutria × bohemica 和 Reynoutria sachalinensis）中哪一种最适合用于刺激种子生长。我们采用引种法测试了三种结缕草的酒精提取物对小麦萌芽和幼苗特征的影响，共监测了 12 项测量特征。与对照组相比，这三种结缕草的提取物普遍都能改善小麦的发芽和生长。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、芽和幼苗长度、根、芽和幼苗干重都有显著差异（方差分析，邓肯检验，α < 0.05）。植物雷诺特里亚属似乎是保护和刺激农作物的可能来源。

期刊介绍： The Science of Nature - Naturwissenschaften - is Springer''s flagship multidisciplinary science journal. The journal is dedicated to the fast publication and global dissemination of high-quality research and invites papers, which are of interest to the broader community in the biological sciences. Contributions from the chemical, geological, and physical sciences are welcome if contributing to questions of general biological significance. Particularly welcomed are contributions that bridge between traditionally isolated areas and attempt to increase the conceptual understanding of systems and processes that demand an interdisciplinary approach.
