“…Symptoms caused by aqueous extracts of RC and PT in B. bipinnata plants may be associated with the presence of allelochemicals in these extracts. Allelopathy can impair plant growth and development through a variety of pathways, such as hormone levels, photosynthesis, respiration, nucleic acid metabolism, and protein synthesis 38 . There are few studies evaluating the phytotoxicity of extracts applied directly to weed leaves in a greenhouse.…”

“…We suggest that one of the main mechanisms affected was photosynthesis, considering that the reduction in leaf chlorophyll impaired the photosynthetic rate, resulting in lower plant growth. Reductions in the growth of various weeds and symptoms of leaf chlorosis are attributed to inhibition of chlorophyll synthesis and pathways related to photosynthesis, nitrogen metabolism, and porphyrin metabolism 15 , 38 .…”

Plant species with allelopathic effects against weeds have emerged as a potential strategy for the development of ecologically friendly bioherbicides. In this study, the allelopathic effects of the plant species Dipteryx lacunifera Ducke, Ricinus communis L., Piper tuberculatum Jacq., and Jatropha gossypiifolia L. on the weed Bidens bipinnata L. were investigated. In vitro bioassays revealed that aqueous extracts of selected plant species were able to inhibit seed germination and seedling growth of B. bipinnata, highlighting the strongest allelopathic effect evidenced by R. communis. The phytotoxicity of the aqueous extracts was evaluated in pot experiments, which indicated that the foliar application of R. communis and P. tuberculatum extracts on B. bipinnata plants caused yellowing of leaves, affecting the chlorophyll content and reducing growth. The discrimination of the plant extracts by attenuated total reflectance Fourier transform mid-infrared (ATR FT-MIR) spectroscopy combined with principal component analysis (PCA) indicated the presence of allelochemical compounds, such as phenolics and terpenoids, which may be associated with allelopathic activity. Overall, this study provides valuable information about the substantial allelopathic inhibitory effects of the plant species R. communis and P. tuberculatum on the weed B. bipinnata, which may be used for the development of eco-friendly bioherbicides.

“…Allelochemicals are economical and eco-friendly compounds for controlling harmful algae because they are easy to access, biodegrade quickly and cause minimal pollution [19]. Many reports have revealed that botanical allelochemicals can significantly suppress the growth and photosynthesis of harmful algae [23][24][25][26][27][28]. The change of chlorophyll a, chlorophyll c and carotenoids might attribute to the photosynthetic system to acclimate the stress, as they are involved in light absorption, light harvesting and photochemistry [29][30][31].…”

“…The suppression of algal growth, pigment content and photosynthetic efficiency are macroscopic expressions of electron transport and ATP synthesis heterogeneity [32,33]. Many allelochemicals have been confirmed as hindering electron transport in algal photosynthetic systems, thus affecting ATP synthesis [28,34,35]. The OJIP fluorescence transient and JIP test, a sensitive probe for PSII heterogeneity, can elaborate changes in photons, excitons, electrons and other metabolites [36].…”

In aquaculture, high-density seaweed farming brings higher economic benefits but also increases outbreaks of diatom felt. The effective control of diatom felt in high-density seaweed farming has always been a research hotspot. This study selected two potential allelochemicals 2-hydroxycinnamic acid and quinic acid to explore their effects on a diatom Nitzschia closterium and an economic seaweed Monostroma nitidum. The results showed that 2-hydroxycinnamic acid had better inhibitory effects than quinic acid on the growth, pigment content and photosynthetic efficiency of N. closterium. Their half-maximal inhibitory concentrations at 120 h (IC 50-120 h ) were 0.9000 and 1.278 mM, respectively. Additionally, these allelochemicals had limited inhibitory effects on the growth, pigment content and photosynthetic efficiency of M. nitidum before 24 h. To further explore the allelopathic effect of these chemicals, this study focused on the photosystem II energy fluxes of N. closterium. It was found that 3 mM 2-hydroxycinnamic acid could destroy the whole photosynthetic system by devastating the PSII reaction centre (RC) before 24 h; however, the same concentration of quinic acid could only down-regulate the electron transport efficiency by changing the effective antenna size of an active RC and downregulating the PSII reaction centre density. These experimental results are expected to provide a new strategy to control diatom felt blooms on the high-density seaweed farming areas.

“…In addition to their direct phytotoxic effects, allelochemicals are known to affect development indirectly by inhibiting the synthesis and/or accumulation of compounds in sugar and triacylglycerol pathway (Belz and Hurle, 2004). Also extract application can trigger the photosynthesis pathway (Chen et al, 2021) Allelochemicals cause many physiological changes in plants resulting with similar and predictable responses. These responses vary according to structure and dose of the allelochemical, genetic potential of the target plant and metabolic pathway (Bao et al, 2019;Inderjit and Mukerji, 2006).…”

The investigation of allelopathic and antimicrobial effects of four different plant extracts is the aim of this study. The aqueous extract of plants (Lepidium draba L., Acroptilon repens (L.) DC., Thymus kotchyanus Boiss&Hohen. var. kotchyanus, Inula peacockiana (Aitch.&Hemsl.) Koravin,) were applied to seedlings of cultivated (Pisum sativum L. and Hordeum vulgare L.) and weed (Amaranthus retroflexus L. and Portulaca oleraceae L.). Seedlings were irrigated with aqueous extract (1 %) for 15 days to observe the physiological responses. The morphological changes, chlorophyll levels and phytohormone concentrations were determined. The Lepidium draba and Inula peacockiana extracts affected development of all of the target seedlings and caused lesion on the leaves. Acroptilon repens and Thymus kotschyanus extracts caused a decrease in gibberellic acid (GA) whereas increase in absisic acid (ABA) levels. For investigation of antimicrobial activities, hexane, methanol and water extracts were prepared. Extracts were applied on Bacillus cereus, Staphylococ aureus, Pseudomonas syringae and Escherichia coli for antibacterial and Rhizoctonia solani, Fusarium oxysporum and Aspergillus niger for antifungal effects. Inula peacockiana and Acroptilon repens extracts had a great antimicrobial activity. While all plant extracts inhibited Rhizoctonia solani, Fusarium oxysporum growth and spore development of Aspergillus niger. The antifungal activity of extracts were better than antibacterial activity. As a conclusion, these plants have allelopathic potential for natural weed control and antimicrobial potential for medicinal uses.
