Resumo: | Anthropogenic activities with polluting potential are a problem of great relevance, as they lead to soil contamination by toxic metals in many parts of the world. The accumulation of these toxic metals is a cause for concern in agricultural production, because it is a group of contaminant metals with high persistence capacity in the environment, because they are bioaccumulative and do not decommand not be easily metabolized by plants. Ni is an essential micronutrient for optimal plant growth at low concentrations, but its toxicity is considered more important than its deficiency, due to the deleterious effects being more aggressive. Excessive Ni concentrations influence the morphological, anatomical and biochemical dynamic of plants. Having said that, there is a growing interest focused on the development and use of potentially queling biomolecules as a viable alternative in the process of soil remediation or plant protection. Having said that, the study aimed to evaluate the protective effect of resveratrol (RES) on nickel-induced phytotoxicity in Lactuca sativa L. seedlings grown in microenvironments. The research was developed in a completely randomized design (IHD), with three replications of 30 lettuce seeds. The study was divided into two experiments, the first consisted of different concentrations of RES and the second of the combinations of non-toxic concentrations of RES with toxic levels of NiSO4, plus the control groups: distilled water and isolated concentrations of RES and NiSO4. Germination, morphological and biochemical parameters were analyzed in cultivated seedlings. The results obtained indicate that NiSO4, when applied alone, caused toxicity in lettuce seedlings, but when we analyzed the NiSO4 + RES combinations, we denoted a significant protective effect of RES on the toxicity caused by NiSO4. Thus, the exogenous application of RES can be a great agricultural promise in the physiology of stress caused by toxic metals, because it has chelating action. However, further studies are needed to improve understanding of the exact mechanisms involved in biomolecule actions. |

O acúmulo desses metais tóxicos é motivo de preocupação na produção agrícola, por se tratar de um grupo de metais contaminantes com alta capacidade de persistência no ambiente, por serem bioacumuláveis e não se decomporem e nem serem facilmente metabolizados pelas plantas. O Ni é um micronutriente essencial para o crescimento ideal das plantas em baixas concentrações, mas sua toxicidade é considerada mais importante que sua deficiência, devido aos efeitos deletérios serem mais agressivos. Concentrações excessivas de Ni influenciam a dinãmica morfológica, anatômica e bioquímica das plantas. Posto isto, há um interesse crescente focado no desenvolvimento e uso de biomoléculas potencialmente quelantes, como uma alternativa viável no processo de remediação de solos ou proteção vegetal. Posto isso, o estudo teve como objetivo avaliar o efeito protetor do resveratrol (RES) sobre a fitotoxicidade induzida por níquel em plântulas de Lactuca sativa L. cultivada em microambientes. A pesquisa foi desenvolvida em delineamento inteiramente casualizado (DIC), com três repetições, de 30 sementes de alface. O estudo foi dividido em dois experimentos, o primeiro consistiu em diferentes concentrações do RES e o segundo das combinações das concentrações não tóxicas do RES com níveis tóxicos do NiSO4, mais os grupos controles: água destilada e concentrações isoladas do RES e NiSO4. Foram analisados parâmetros de germinação, morfológicos e bioquímicos nas plântulas cultivadas. Os resultados obtidos indicam que o NiSO4, quando aplicado isoladamente, causou toxicidade nas plântulas de alface, mas quando analisamos as combinações NiSO4 + RES, denotamos um efeito protetor significativo do RES sobre a toxicidade causada por NiSO4. Assim, a aplicação exógena do RES pode ser uma grande promessa agrícola na fisiologia de estresse causado por metais tóxicos, por possuir ação quelante. No entanto, são necessários novos estudos para melhorar a compreensão dos mecanismos exatos envolvidos nas ações da biomolécula.Submitted by (ana.araujo@ufrpe.br) on 2023-08-10T18:44:51Z No. of bitstreams: 1 Rosemeire Santos Costa.pdf: 2302363 bytes, checksum: 5003f121f9fa9106b12bb44b695c716a (MD5)Made available in DSpace on 2023-08-10T18:44:51Z (GMT).

Anthropogenic activities with polluting potential are a problem of great relevance, as they lead to soil contamination by toxic metals in many parts of the world. The accumulation of these toxic metals is a cause for concern in agricultural production, because it is a group of contaminant metals with high persistence capacity in the environment, because they are bioaccumulative and do not decommand not be easily metabolized by plants. Ni is an essential micronutrient for optimal plant growth at low concentrations, but its toxicity is considered more important than its deficiency, due to the deleterious effects being more aggressive. Excessive Ni concentrations influence the morphological, anatomical and biochemical dynamic of plants. Having said that, there is a growing interest focused on the development and use of potentially queling biomolecules as a viable alternative in the process of soil remediation or plant protection. Having said that, the study aimed to evaluate the protective effect of resveratrol (RES) on nickel-induced phytotoxicity in Lactuca sativa L. seedlings grown in microenvironments. The research was developed in a completely randomized design (IHD), with three replications of 30 lettuce seeds.

Germination, morphological and biochemical parameters were analyzed in cultivated seedlings. The results obtained indicate that NiSO4, when applied alone, caused toxicity in lettuce seedlings, but when we analyzed the NiSO4 + RES combinations, we denoted a significant protective effect of RES on the toxicity caused by NiSO4. Thus, the exogenous application of RES can be a great agricultural promise in the physiology of stress caused by toxic metals, because it has chelating action.
