This study evaluated the phytotoxic

This study evaluated the phytotoxic potential and antioxidant activity of Tagetes patula and Tagetes erecta,
and total phenols and flavonoids of the extracts were quantified. Laboratory bioassays for both pre- and postemergence
were performed in Lactuca sativa L. seeds and in the Allium cepa seeds test. The antioxidant activity
was evaluated by DPPH radical scavenging and reducing power of iron, besides total phenols and flavonoids
quantification in the extracts. Thus, was observed a reduction in the mitotic index when in compared with the
negative control. Was observed also a reduction the germination and development of tested seedlings and was
verified a considerable antioxidant potential and presence of flavonoids and phenolic compounds in the extracts.
According to these results, it is possible to conclude that T. erecta and T. patula have phytotoxic compounds that
may enhance and expand their use in the management of organic agriculture, mainly in vegetables.

Hierdie studie geëvalueer die potensiële fitotoksiese en Tagetes erecta en antioksidant aktiwiteit van Tagetes patula,
en totale fenole en flavonoïede van die uittreksels is gekwantifiseer. Laboratorium bioassays vir beide pre-en na-opkoms
is uitgevoer in Lactuca sativa L. sade en sade in die Allium cepa toets. Die anti-oksidant aktiwiteit
is geëvalueer deur DPPH radikale blaas en die vermindering van krag van Yster, totale fenole en flavonoïede buiten
kwantifisering in die uittreksels. Dus, 'n vermindering in die mitotiese indeks is waargeneem in vergelyking met die
negatiewe kontrole. Was ook waargeneem 'n vermindering van die getoets saailinge Ontkieming en Ontwikkeling en was
'n aansienlike Verified antioksidant flavonoïede en fenoliese verbindings potensiaal en teenwoordigheid in die uittreksels.
Volgens hierdie resultate, is dit moontlik om tot die gevolgtrekking dat T. erecta en T. patula het fitotoksiese. verbindings wat
kan verhoog en uit te brei hul gebruik in die bestuur van Organiese Landbou, hoofsaaklik in groente.
