“…Similar findings were observed on the effects of other natural compounds on seedling growth of weeds (Leather and Einhellig, 1985;Chung and Miller, 1995;Abdelgaleil et al, 2009;Saad et al, 2012). Among the isolated oils, only the essential oil of C. limon was reported to possess allelopathic effect against Euphorbia heterophylla and Ipomoea grandifolia (Ribeiro and Lima, 2012). However, the inhibitory effects of essential oils of different plant species on seedling growth were reported (Duke et al, 2000;Dayan et al, 2009;Krifa et al, 2011;Yang et al, 2012).…”

Essential oils of four Citrus species, Citrus aurantifolia, C. limon, C. paradisi and C. sinensis, were extracted from fruit peels by hydrodistillation. The chemical composition of the isolated oils was analyzed by gas chromatography/mass spectrometry (GC-MS). Effect of the isolated essential oils on seed germination and seedling growth of Silybum marianum was evaluated. The essential oils were also tested for their molluscicidal and insecticidal activities against the adults of Theba pisana snails and the fourth instar larvae of Spodoptera littoralis. Chemical analysis showed that dl-Limonene was the major component in the four essential oils and represented 40.19, 56.30, 74.29 and 89.23% of C. aurantifolia, C. limon, C. paradisi and C. sinensis, respectively. In general, the four oils were characterized to be rich in monoterpene hydrocarbons and oxygenated monoterpenes. Allelopathic experiment on S. marianum revealed that the tested oils reduced the germination percentages at all of the tested concentrations. The oil of C. aurantifolia caused the highest germination reduction at concentration of 10 μL/ Petri dish where 26.7 % of seeds were germinated. The oil of C. sinensis was the most potent inhibitor for root and shoot growth of S. marianum with EC50 values of 2.5 and 6.97 μL/Petri dish, respectively. The tested oils were more effective in reducing the growth of roots than shoots, except for C. paradise which stimulated the root growth. On the other hand, the tested oils showed strong fumigant toxicity against the adults of T. pisana snail with C. sinensis oil (LC50 = 14.2 μL/L) being the most potent one. Also, the tested oils possessed a remarkable toxic effect against the fourth instar larvae of S. littoralis and the oils of C. aurantifolia and C. sinensis had the highest toxic effect with LC50 values of 6.84 and 6.88 μL/L, respectively. The findings of the present study suggest that the essential oils have a potential to be used for pest control.

Herbicidal Activities of Some Allelochemicals and Their Synergistic Behaviors toward Amaranthus tricolor L.

2017

Seven allelochemicals, namely R-(+)-limonene (A), vanillin (B), xanthoxyline (C), vanillic acid (D), linoleic acid (E), methyl linoleate (F), and (±)-odorine (G), were investigated for their herbicidal activities on Chinese amaranth (Amaranthus tricolor L.). At 400 μM, xanthoxyline (C) showed the greatest inhibitory activity on seed germination and seedling growth of the tested plant. Both vanillic acid (D) and (±)-odorine (G) inhibited shoot growth, however, apart from xanthoxyline (C), only vanillic acid (D) could inhibit root growth. Interestingly, R-(+)-limonene (A) lightly promoted root length. Other substances had no allelopathic effect on seed germination and seedling growth of the tested plant. To better understand and optimize the inhibitory effects of these natural herbicides, 21 samples of binary mixtures of these seven compounds were tested at 400 μM using 0.25% (v/v) Tween® 80 as a control treatment. The results showed that binary mixtures of R-(+)-limonene:xanthoxyline (A:C), vanillin:xanthoxyline (B:C), and xanthoxyline:linoleic acid (C:E) exhibited strong allelopathic activities on germination and seedling growth of the tested plant, and the level of inhibition was close to the effect of xanthoxyline (C) at 400 µM and was better than the effect of xanthoxyline (C) at 200 µM. The inhibition was hypothesized to be from a synergistic interaction of each pair of alleochemicals. Mole ratios of each pair of allelochemicals ((A:C), (B:C), and (C:E)) were then evaluated, and the best ratios of the binary mixtures A:C, B:C and C:E were found to be 2:8, 2:8, and 4:6 respectively. These binary mixtures significantly inhibited germination and shoot and root growth of Chinese amaranth at low concentrations. The results reported here highlight a synergistic behavior of some allelochemicals which could be applied in the development of potential herbicides.

“…This study shows the results of the application of an orange pastazzo water extract produced using hydrodynamic cavitation on seed germination at different stages. OPWE was produced as an emulsion of stable terpenic composition, highly rich in limonene and a-terpineol monoterpenes relative to essential oils of different orange cultivars-in line with other studies [54][55][56][57][58][59][60]. Orange essential oils or pure limonene have demonstrated some inhibitory effect on seed germination [61,62], but no tests have been carried out so far with OPWE.…”

A byproduct from orange juice processing known as pastazzo represents a significant organic waste stream. Rich in essential oils and known for its inhibitory effect on plant germination, pastazzo could serve as a valuable input for agricultural purposes. This study assesses the effects of a 40% w/v orange pastazzo water extract (OPWE) produced by hydrodynamic cavitation on the germination of two species, one of economic interest (Lactuca sativa L.) and one common weed (Chenopodium album L.). Three dilutions of OPWE in water (25%; 50%; 75%) were compared to a control treatment in four experiments, using (i) seeds in Petri dishes; (ii) seeds in commercial substrate; (iii) C. album seeds and transplanted L. sativa in commercial substrate; and (iv) other weeds in an open-field plantation of L. sativa. Highly rich in limonene, OPWE applied at higher concentrations in Petri dishes caused the effective inhibition of germination in C. album and a germination delay in L. sativa. Similar results were observed in the germination of the two species in commercial substrate, with none of the dilutions affecting L. sativa biomass. In the field experiment, despite a relatively low number of weeds in the control treatment, higher OPWE concentrations reduced the number of grasses and forbs, largely confirming the inhibitory effects. We conclude that OPWE produced with hydrodynamic cavitation, an efficient and affordable method of extraction, represents an effective crop treatment due to the species-specific effects of its constituent limonene on plant germination. Further tests are essential to understand the extent to which OPWE interacts with other species and types of substrate.
