“…Inhibition of cell division was observed in lettuce treated with BOA (1 mM; Sánchez-Moreiras et al 2008), bean ( Pisum sativum L.) exposed to sorgoleone (0.1 mM; Gattás-Hallak et al 1999) or cockspur grass grown in extract of chinese perfume plant ( Aglaia odorata Lour. ; Teerarak et al 2012).

Cyanamide (CA) has been reported as a natural compound produced by hairy vetch (Vicia villosa Roth.) and it was shown also to be an allelochemical, responsible for strong allelopathic potential in this species. CA phytotoxicity has been demonstrated on various plant species, but to date little is known about its mode of action at cellular level. Treatment of tomato (Solanum lycopersicum L.) roots with CA (1.2 mM) resulted in inhibition of growth accompanied by alterations in cell division, and imbalance of plant hormone (ethylene and auxin) homeostasis. Moreover, the phytotoxic effect of CA was also manifested by modifications in expansin gene expression, especially in expansins responsible for cell wall remodeling after the cytokinesis (LeEXPA9, LeEXPA18). Based on these results the phytotoxic activity of CA on growth of roots of tomato seedlings is likely due to alterations associated with cell division.Electronic supplementary materialThe online version of this article (doi:10.1007/s00425-012-1722-y) contains supplementary material, which is available to authorized users.

“…However, the thresholds of odorin for the growth and germination inhibition on E. crus-galli were 1000 and 4000 ppm, respectively. Thus, the inhibitory activity of odorine was by far less than that of A. odorata leaf extracts and its powders [9]. The objective of this study were to isolate and characterize the major active phytotoxic substance causing the strong allelopathic effect of A. odorata leaf extracts and is the main contributor to the bioherbicide PORGANIC TM .…”

Aglaia odorata Lour. (Meliaceae) was found to have very strong allelopathic activity and a bioherbicide PORGANIC(™) was developed from its leaf extracts. However, the phytotoxic substances causing the strong allelopathic activity of the plants have not yet been determined. Therefore, we investigated allelopathic properties and phytotoxic substances in A. odorata. Aqueous EtOH extracts of A. odorata leaves inhibited root and shoot growth of garden cress (Lepidum sativum), lettuce (Lactuca sativa), alfalfa (Medicago sativa), timothy (Phleum pratense), ryegrass (Lolium multiflorum), and Echinochloa crus-galli with the extract concentration-dependent manner. The extracts were then purified and a major phytotoxic substance with allelopathic activity was isolated and identified by spectral data as rocaglaol. Rocaglaol inhibited the growth of garden cress and E. crus-galli at concentrations > 0.3 and 0.03 μm, respectively. The concentrations required for 50% inhibition ranged from 0.09 to 2.5 μm. The inhibitory activity of rocaglaol on the weed species, E. crus-galli, was much greater than that of abscisic acid. These results suggest that rocaglaol may be a major contributor to the allelopathic effect of A. odorata and bioherbicide PORGANIC(™) .

“…It has been recognized that allelochemicals could be released from plants into the environment through several ways such as volatilization, root exudation, decomposition and leaching to interfere the growth of adjacent plants (Subrahmaniam et al ., 2018). Some allelochemicals could increase cell membrane permeability (Bais et al ., 2003; Chai et al ., 2013), inhibit cell division and elongation, damage cell sumicroscopic structure (Teerarak et al ., 2012; Cheng et al ., 2016), disturb plant photosynthesis and respiration (Yu et al ., 2005), affect synthesis of plant endogenous hormones and proteins (Zeng et al ., 2001; Hu et al ., 2015), and so on. In consequence, allelopathy would potentially influence the growth and development of plants, succession of plant communities (Cummings et al ., 2012; Bonanomi et al ., 2018) and invasion of exotic plant into forest ecosystems (Meiners et al ., 2012).…”

Global warming in conjunction with various biotic or abiotic interferences has been jeopardizing the ecosystem of boreal forests. By integrating field inspection with experimental simulation, this work comprehensively investigated the allelopathic effects of a key allelochemical 3,4-dihydroxyacetophenone (DHAP) in the exudates of P. schrenkiana needles on its seed and seedling growth, endogenous hormone metabolism and antioxidant enzyme activity, identified the existence of DHAP allelopathy duality at a certain temperature with an inflection concentration point (e.g. about 0.25 mM at dark/light temperature of 4/12 °C) as the boundary between promotional and inhibitory effect, and verified that the inflection point of DHAP concentration would inevitably shift to a lower level as temperature increased. Consequently, this paper gives a scientific explanation into the intrinsic mechanism of P. schrenkiana degradation due to allelopathy, but also presents a new approach to explore the relationship between forest evolution and global warming.
