Senna occidentalis is an invasive plant producing a series of allelochemicals that might inhibit the development of other plants. The objective of this study was to assess the phytotoxic effect of S. occidentalis extracts on the germination, development and antioxidant defence of the native species Tabebuia chrysotricha, T. pentaphylla, T. roseoalba and Handroanthus impetiginosus (Ipê species).• We evaluated the effects of chemicals extracted from S. occidentalis on the germination rate, germination speed index (GSI) and biometric parameters of the test species under controlled conditions. The effect of the extracts on the pigment content, amount of H 2 O 2 and malondialdehyde (MDA), and the activity of the antioxidant enzymes in roots and leaves were also tested.• Alkaloids, coumarins, phenols, saponins, free steroids and condensed tannins were present in all extracts of S. occidentalis, while catechins were present only in leaf and stem extracts. Stem and root extracts caused a growth reduction in all Ipê species and total inhibition of seed germination in T. chrysotricha and T. roseoalba. All target species showed an increase in H 2 O 2 and MDA in radicles and leaves. Oxidative stress contributed strongly to the morphological changes, such as seed blackening, thinning and darkening of radicle tips and reduction of biomass allocation in all Ipê species.

praça-fontes 1,3* the intensive application of agrochemicals in crops has negatively impacted the environment and other organisms. The use of naturally occurring compounds may be an alternative to mitigate these effects. Plants are secondary metabolite reservoirs and may present allelopathic activity, which is potentially interesting to be used in bioherbicide formulations. In this context, the present work aimed to evaluate the phytotoxic and cytotoxic effects of essential oils extracted from leaves of Sparattanthelium botocudorum and Sparattanthelium tupiniquinorum in bioassays with the plant models Lactuca sativa L. and Sorghum bicolor L. Moench. The essential oils were applied at concentrations of 3,000, 1,500, 750, 375 and 187.5 ppm. Chemical characterization of the oils was performed, and their impact on the percentage of germinated seeds, initial development of L. sativa and S. bicolor seedlings, and changes in the mitotic cycle of meristematic cells from L. sativa roots was evaluated. The major compound of the essential oils was germacrene D, followed by bicyclogermacrene, β-elemene and germacrene A. The phytotoxicity assay showed that the essential oils of both species reduced the root and shoot growth in L. sativa and decreased the germination and shoot growth in S. bicolor. Inhibition was dependent on the tested oil concentration. In the cytotoxicity assay, a decrease in mitotic index and chromosomal and nuclear alterations were observed, which resulted from aneugenic and clastogenic action. Herbicides, which are used for weed control 1 , are among the most applied agrochemicals in crop fields. However, the use of these compounds has led to problems related to plant resistance, environmental contamination, and risks to human and animal health. Therefore, it is necessary to find alternative methods for agricultural pest control 2,3. In this context, secondary metabolites may be of particular interest, as they can be directly or indirectly used in the development of new herbicides. These compounds are produced by plants and comprise three major groups, which are found in extracts and essential oils: terpenoids, alkaloids and phenolic compounds 4,5. Essential oils play an important role in protecting the plant during the competition with other species as well as against herbivore and pest attacks, and are produced variably according to the plant's interactions with the environment 6. Essential oils are volatile products, found in all plant organs, and are obtained by extraction processes such as hydrodistillation and cold pressing, depending on plant location, quantity and characteristics required for the final product 7-9. The identification and phytochemical classification of these oils enable the investigation of biologically active substances 10-12. Known as allelochemicals, these substances can be a favorable source for the development of natural herbicides, which may contribute to reduce the environmental impact caused by commercial herbicides, and additionally serve as plant growth stimulants 13-16 .

“…The phyto-cyto-genotoxicity and mutagenicity analysis, besides the determination of mechanisms of action are types of tests performed to determine the herbicidal potential of the studied compounds. These tests present clear and efficient results in a short period of time, use model organisms (both mono and eudicotyledonous), present low cost and use, as test organisms, plants that show results correlated with those found in mammals (Carvalho et al, 2019;dos Santos et al, 2018;Silveira et al, 2017).…”

The use of agrochemicals has influenced the increase in agricultural productivity. However, the concern about damage to the human health and to the environment, resulting from the indiscriminate use of pesticides, has increased worldwide. Alternative methods for controlling pests and diseases have been proposed to maintain productivity and quality of life. A possibility is to use compounds produced by the secondary metabolism of plants, such as the essential oils. Some of these substances perform inhibitory or stimulatory activity on the development of other organisms. Plants from the genus Eucalyptus have been investigated and were chosen to be studied in the present work, due to the traditional knowledge regarding the potential of the essential oils from some species, as well as, for the need to use residues from their production. Therefore, were determined the yield, identified the compounds from the essential oils of E. urophylla and the hybrid E. urophylla x E. camaldulensis, and evaluated their biological activity through bioassays, investigating the phyto-cyto-genotoxicity and mutagenicity using Lactuca sativa and Sorghum bicolor as model plants. The essential oil from the hybrid provided a higher yield. Eucalyptol was the major compound identified for both oils, representing more than 85% of the compounds present. Both E. urophylla and the hybrid showed phyto-cyto-genotoxic, mutagenic effects, and clastogenic and aneugenic mechanisms of action, promoting epigenetic changes in the meristematic cells of L. sativa. The results point out to the bioherbicidal potential of these essential oils.
