“…Similarly, Farris and Murray (2006) reported that 3.2 plants m −1 of V. encelioides row resulted in a 50% reduction in peanut yield. Mehal et al (2022) also suggested that V.encelioides competitively excludes its neighboring plants by allelopathic interference.…”

“…Similarly, Singh et al (2018) stated that weeds, unlike crops, are better adapted to moisture stress, that is, both drought and waterlogging effects.

The wild sunflower, an invasive alien species, is known to affect the performance of field crops. A field experiment was conducted to estimate the effects of different levels of wild sunflower and common bean densities on common bean yield components and grain yield, as well as to quantify yield loss due to their competition at varying densities. The experiment was laid out in a randomized complete block design in a factorial arrangement with four replications. Hence, factorial combinations of three common bean densities and five wild sunflower densities were tested at two locations. At 24 plants m−2, wild sunflower had maximum dry biomass of 413.84 and 549.83 g−2 at Adamitulu and Melkassa, respectively. An increase in wild sunflower density from 0 to 24 plants m−2 resulted in a reduction of pods per plant up to 62.41% and 83.11%, respectively, at Adamitulu and Melkassa. Compared to the weed‐free plot, the highest wild sunflower density (24 plants m−2) had a 4.6‐fold reduction in seed per pod. Weed‐free plots at Adamitulu and Melkassa yielded the highest grain yields of 2.77 and 3.37 t ha−1, respectively. Common bean grain yield reduced by 88.12% and 67.64%, in Adamitulu and Melkassa, due to the highest density of wild sunflower. The rectangular hyperbolic equation fits common bean grain yields well. This study, hence, proposes that wild sunflower plants be kept at a density of no more than three plants per meter square to minimize severe yield loss and help common bean growers make decisions on wild sunflower control.

“…Additionally, test plants exposed to allelopathic extract had proline accumulation, according to some studies (Al-Taisan 2014, El-Khatib et al 2016. Either the suppression of chlorophyll formation or the activation of molecules that destroy chlorophyll could be the cause of the significant drop in chlorophyll content seen at all concentrations (Mehal et al 2023). Allelochemicals can hinder oxygen development and photosynthesis through their interactions with components of photosystem II (Leu et al 2002).…”

Allelopathy involves plants releasing allelochemicals, inhibiting nearby plants' growth and influencing their physiological and morphological characteristics. Donor plants with allelopathic capabilities dominate, impacting the survival of other plant species. The effect of Lepidium didymum stem aqueous extracts (SAE) on Lens culinaris and Melilotus alba was investigated in this study. The experiment involved extracting compounds from the stems of Lepidium didymum and applying varying concentrations (0.5, 1, 2, and 4%) of these stem extracts to test plant seeds and seedlings. Multiple parameters, including germination percentage, growth parameters, and biochemical activities, were measured and compared against the control group. Germination percentage, seedling growth, seedling length, fresh and dry biomass, chlorophyll, and carotenoid content decreased notably, especially at higher concentrations (4%), while proline content increased in a concentration-dependent manner. In 2021–2022, the experiment was carried out in the allelopathy laboratory department of Botany Aligarh Muslim University, Aligarh. Scanning electron microscopy revealed ultrastructural abnormalities in the roots of the treated plants as compared to the control. Using GCMS analysis, 32 volatile chemicals were found in the methanolic extract of the stem. The compounds found in the major amounts are benzyl nitrile (291.19%), lauric acid (7.86%), benzene acetic acid (6.44%), 11-bromoundecanoic acid (7.36%), palmitic acid (4.85%), dodecanoic acid (4.80%), menthol, trans-1,3, cis-1,4 (3.28%), 11-bromoundecanoic acid (7.36%), and linolenic acid (8.64%). These compounds may be responsible for imparting an allelopathic effect on the test species, Lens culinaris and Melilotus alba. Our study revealed that the stem of L. didymum possesses a high concentration of water-soluble allelochemicals, which are thought to have reduced test plants’ growth and can be used as potential weedicides.

“…The role of flavonoids as allelopathic molecules has been largely acknowledged [118][119][120]. Often, unique compounds are specifically synthesized, as in the case of the barley-produced saponarin, a newly identified flavonoid, to suppress Bromus diandricus spread [121].…”

Flavonoids Are Intra- and Inter-Kingdom Modulator Signals

Flavonoids are a broad class of secondary metabolites with multifaceted functionalities for plant homeostasis and are involved in facing both biotic and abiotic stresses to sustain plant growth and health. Furthermore, they were discovered as mediators of plant networking with the surrounding environment, showing a surprising ability to perform as signaling compounds for a multitrophic inter-kingdom level of communication that influences the plant host at the phytobiome scale. Flavonoids orchestrate plant-neighboring plant allelopathic interactions, recruit beneficial bacteria and mycorrhizal fungi, counteract pathogen outbreak, influence soil microbiome and affect plant physiology to improve its resilience to fluctuating environmental conditions. This review focuses on the diversified spectrum of flavonoid functions in plants under a variety of stresses in the modulation of plant morphogenesis in response to environmental clues, as well as their role as inter-kingdom signaling molecules with micro- and macroorganisms. Regarding the latter, the review addresses flavonoids as key phytochemicals in the human diet, considering their abundance in fruits and edible plants. Recent evidence highlights their role as nutraceuticals, probiotics and as promising new drugs for the treatment of several pathologies.
