ABSTRACT = {Allelopathic plants are important resources for the discovery of bioherbicides. Rosebay willowherb [<i>Chamaenerion angustifolium</i> (L.) Scop. syn. <i>Epilobium angustifolium</i> L.] widely distributes in Western Asia, Europe, and North
America, and behaves as a dominant species within the community due to the
production of substances that restrict growth of other plants. This study aims at
investigating the allelopathic potential of rosebay willowherb by evaluation of
the effects of aqueous extracts from different parts on seed germination and seedling
growth in lettuce (<i>Lactuca sativa</i> L.), as well as measuring the accumulation of
reactive oxygen species and structural analysis of root tips via scanning electron
and transmission electron microscopy. It was observed that the aqueous extracts
from the leaves of rosebay willowherb had the strongest inhibitory effect on the germination index, germination energy and total germination of lettuce seeds, followed
by capsular fruits and flowers, and the inhibition effect of stems was the weakest.
All aqueous extracts (100 mg/mL) showed a significant inhibitory effect on radicle
elongation of lettuce seedlings. Additionally, after treatment with the aqueous
extract of rosebay willowherb leaves, accumulation of reactive oxygen species
increased in columella cells, which correlated with disruption of root tip structure.},
