“…The only similar duration of juglone treatment was described in the case of two species of Medicago [24] and soybean [22]. The analysis of Medicago under the influence of juglone showed that at least one species, M. lupulina, was tolerant to this chemical after 7 days of treatment [24]. Thus, the results presented here are in accordance with at least these findings and suggest that juglone may have no harmful effect on plants [31].…”

“…Therefore, it is difficult to compare our results with most of the literature data. The only similar duration of juglone treatment was described in the case of two species of Medicago [24] and soybean [22]. The analysis of Medicago under the influence of juglone showed that at least one species, M. lupulina, was tolerant to this chemical after 7 days of treatment [24].…”

“…A plant's reaction to stress in the form of temporally increased cell division has been postulated in the literature [32][33][34]. Molecular analysis also showed that the response of a plant to stress conditions was correlated with an increase in the expression of stress response genes [24].…”

“…Juglone has been found to be an inhibitor of seed germination in cress, tomato, cucumber, alfalfa, radish, and watermelon [8,[19][20][21]. A decrease in the growth of roots and seedlings that were under the influence of juglone was also described for many plants including soybean [22], corn [23], Medicago [24], cucumber [25], and also for some trees and shrubs [26].…”

“…However, if we take into consideration the fact that allelochemicals can be beneficial in one species and harmful in another one and that this depends on the type and concentration of the allelochemicals and on the duration of the treatment [16][17][18], the growth stimulation that was observed in the presented studies is not improbable. At present, it appears that there are some plants that are tolerant to juglone [24]. It is possible that the concentration, duration of the treatment, and the way that juglone is applied may be important factors that change the reaction of plants to this allelochemical.…”

Morpho-histological analysis of tomato (Solanum lycopersicum L.) plants after treatment with juglone

Juglone is a substance that limits plant growth and has a toxic effect on plant development. In this study, we analyzed the influence of juglone at two different concentrations (10 −3 M and 10 −4 M), which were applied to different parts of Solanum lycopersicum L. plants (root system, stem after decapitation, and surface of a younger leaf or after autografting) for a short period of time (7 days), on the morphology and histology of stems. At a lower concentration, juglone had positive effects on plant growth, which resulted in an increase in interfascicular cambial cell divisions, faster development of a continuous cambium layer along the stem circumference, and development of fibers. Additionally, under the influence of juglone, the number of developing leaves increased and adventitious roots developed. The results are discussed based on the current literature concerning the reaction of plants to juglone and to stress conditions.

BackgroundClimate change and growing global population are driving forces that shift the agriculture from open fields to environmentally‐controlled confined systems. In such confined systems, plants are adapted to unique light spectra to achieve maximal qualitative and quantitative yields. In the present study, effects of five light spectra on morpho‐physiological and molecular attributes of peppermint were examined. Treatments included a traditional greenhouse considered as the control, a fluorescent light, and four types of light emitting diodes (LED): red, blue, red‐blue (70:30), and white. Leaf samples were collected from plants and analyzed for volatile constituents using a headspace GC–MS. Meanwhile, changes in the expression profile of genes involved in the biosynthesis of menthol were evaluated.ResultsOur results showed that maximal yield (wet and dry biomass) was achieved under greenhouse condition and the red‐blue LED. Application of the red‐blue LED resulted in maximal production of beneficial monoterpenes, which indicate superiority to greenhouse environment. A significant change in the gene expression profile was observed among plants grown under different light treatments. The red‐blue LED was associated with a significant up‐regulation of key genes in the menthol biosynthesis (menthol dehydrogenase and pulegone reductase). This phenomenon was consistent with a higher menthol production under the same condition.ConclusionThe application of red‐blue LED was associated with the highest level of yield and menthol production, whereas it resulted in lower concentrations of unfavorable by‐products (isomenthol, cis‐pulegone, and menthofuran). In conclusion, 70:30 red‐blue LED can be satisfactory applied to maximize growth yield and optimize favorable bioactive constituent in peppermint.

Application of conventional synthetic pesticides and agrochemicals has boosted the yield and productivity of crops by reducing pest infestation and promoting crop growth yet increasing reliance on many of these products poses serious environmental threats. This has led to growing interest in obtaining more environmentally friendly alternatives to conventional pesticides and agrochemicals. Allelochemicals produced by plants, fungi, and microbes offer options for developing novel natural product-based pesticides and agrochemicals that are effective but with lower environmental half-lives. Here, we review the current state of knowledge about the potential use of juglone (5-hydroxy-1,4-naphthoquinone), the allelochemical produced by black walnut trees (Juglans nigra), which has been investigated for applications across a range of different agricultural purposes. We then offer our perspective on what opportunities and challenges exist for harnessing juglone as a component of sustainable agriculture.
