crescimento de especies nativas de cerrado e de Vetiveria zizanioides em processos de revegetacao de vocorocas
Ciencia Florestal, 2014Co-Authors: Thamy Evellini Dias Marques, Hudson Eustaquio Baeta, Mariangela Garcia Praca Leite, Sebastiao Venâncio Martins, Alessandra Rodrigues KozovitsAbstract:Rates of seed germination, plant survival and growth, as measured in the present study, are essential parameters to characterize the biological potential of species for the restoration of degraded areas. The lack of knowledge about these aspects in native species has justified the use of exotic plants in Brazilian gullies revegetation. However, especially in places subject to highly seasonal climate and on oligotrophic soils, exotic species do not always perform well, leading to revegetation failure or significantly increasing the cultivation care needs. To improve the knowledge concerning to the biological potencial of cerrado native species and of an exotic grass which has been used for erosion contention, in the present study, seedlings and clumps of native cerrado species, Cratylia argentea (Desv.) Kuntze and Echinolaena inflexa (Poir.) Chase, and of the exotic grass Vetiveria zizanioides (L.) Nash, were transferred to a gully colluvium in Ouro Preto, Minas Gerais state, where they remained during the dry season of 2010 without application of fertilizers or irrigation. In randomized block design, plots of 1 x 1 m received four planting treatments: clumps of Echinolaena inflexa or Vetiveria zizanioides, and clumps of these grasses intercropped with the legume Cratylia argentea. All grasses and 73% of the legume seedlings survived. As expected, the green cover of Echinolaena inflexadecreased throughout the dry season, however, showing regrowth after the first rains. Leaf area of Vetiveria zizanioides remained active and grew significantly in the period. Cratylia argentea showed high rates of germination and growth; however, nodulation occurred in only two individuals. Thus, there was no influence of the legume on grasses growth. Results indicate that both native species and the exotic grass tested are potential successful plants for gullies replanting. Plants survived and grew on low nutrient substrate and during the critical period of drought without any fertilizer or irrigation application.

crescimento de especies nativas de cerrado e de Vetiveria zizanioides em processos de revegetacao de vocorocas growth of cerrado native species and of Vetiveria zizanioides in colluvium of gullies
2014Co-Authors: Thamy Evellini Dias Marques, Hudson Eustaquio Baeta, Sebastiao Venâncio Martins, Mariangela Garcia, Praca Leite, Alessandra Rodrigues KozovitsAbstract:Taxas de germinacao de sementes, sobrevivencia e crescimento de plantas, parâmetros estes avaliados no presente estudo, sao informacoes essenciais para a caracterizacao do potencial biologico de especies para uso em processos de recuperacao de areas degradadas. A falta de conhecimento sobre tais aspectos em especies nativas tem justificado o uso de plantas exoticas na revegetacao de vocorocas em todo o Brasil. Entretanto, especialmente em locais sujeitos a grande sazonalidade climatica e sobre solos oligotroficos, especies exoticas nem sempre apresentam bom desempenho, levando o empreendimento de revegetacao ao insucesso ou elevando consideravelmente a necessidade de aplicacao de tratos culturais. Com o objetivo de ampliar os conhecimentos sobre o potencial biologico para revegetacao em vocorocas de plantas nativas do cerrado e de uma graminea exotica, que vem sendo amplamente usada em projetos de contencao de erosao, plântulas e touceiras das especies nativas Cratylia argentea (Desv.) Kuntze e Echinolaena inflexa (Poir.) Chase, e da exotica Vetiveria zizanioides (L.) Nash foram transferidas para o coluvio de uma vocoroca no municipio de Ouro Preto - MG, onde permaneceram durante a estacao seca de 2010 sem aplicacao de fertilizantes ou irrigacao. Em blocos ao acaso, parcelas de 1 x 1 m receberam aleatoriamente quatro tratamentos de plantio: touceiras de Echinolaena inflexa ou de Vetiveria zizanioides; e touceiras destas gramineas em consorcio com a leguminosa arbustiva Cratylia argentea. Todas as gramineas e 73% das plântulas da leguminosa sobreviveram. Como esperado, a cobertura verde de Echinolaena Inflexa diminuiu ao longo da estacao seca, tendo, entretanto, rebrotado apos as primeiras chuvas. Vetiveria zizanioides manteve a area foliar ativa e apresentou crescimento significativo no periodo. Cratylia argentea apresentou altas taxas de germinacao de sementes e de crescimento, entretanto, nodulacao ocorreu em apenas dois individuos. Assim, nao houve influencia da leguminosa no crescimento das gramineas. Os resultados indicam que tanto as especies nativas do cerrado como a graminea exotica possuem alto potencial para revegetacao em coluvio de vocoroca, tendo sobrevivido ao periodo critico de seca e sobre substrato oligotrofico sem adicao de fertilizantes ou irrigacao. Palavras-chave: Cratylia argentea; Echinolaena inflexa; revegetacao; vocoroca.

screening of phytochemical and antibacterial activity of hemidesmus indicus l and Vetiveria zizanoides l
European Journal of Experimental Biology, 2012Co-Authors: K Subha, G SenthilkumarAbstract:The screening and study of selected Indian medicinal plants Hemidesmus indicus (L.) and Vetiveria zizanoides (L.) were selected for phytochemical screening and antibacterial studies. The solvents used for the extraction of plant roots were ethanol,methanol and distilled water. The invitro antibacterial activity was performed by agar well diffusion method. The most susceptible Gram-Postive and Gram-negative bacteria were tested. The extracts of plant Hemidesmus indicus (L.) and Vetiveria zizanoides (L.) inhibited the growth of the bacterial strains investigated. The most active extracts were compared with the standard antibiotics, penicillin, Streptomycin and Ampicillin 100mg/disc). The results obtained in the present study suggest that preliminary phytochemical analysis detected the presence of Alkaloids, Aminoacid, Flavonoids Saponins and Tanins. The Hemidesmus indicus (L.) and Vetiveria zizanoides (L.) could be used in treating diseases caused by the test organisms. The results are discussed in detail.

nitrate removal in vertical flow constructed wetland planted with Vetiveria zizanioides effect of hydraulic load
Ecological Engineering, 2017Co-Authors: Adelaide Almeida, Fatima Carvalho, Maria J Imaginario, Ivone Castanheira, Ana R Prazeres, C RibeiroAbstract:Abstract A vertical flow constructed wetland (VFCW) planted with Vetiveria zizanioides (0.24 m2 × 0.70 m) intended to receive a synthetic wastewater with high nitrate concentration was used to study the influence of the hydraulic load (HL) increase on nitrate load removal, keeping a low carbon nitrogen ratio (C/N). The inlet nitrate concentration was kept constant ([NO3−] = 83 ± 7 mg L−1) and four different levels of HL were used, from 148 ± 5 to 473 ± 5 L m−2 d−1; accordingly, nitrate load increased from 12.4 ± 0.7 g m−2 d−1 to 39.9 ± 0.7 g m−2 d−1. The nitrate load removal occurred in all trials, increasing proportionally to HL and nitrate load applied, reaching a maximum value of 11.9 ± 0.7 g m−2 d−1 at a nitrate load applied of 20.4 ± 1.2 g m−2 d−1 and HL of 239 ± 7 L m−2 d−1. Beyond that maximum, a further increase in HL or nitrate load applied led to a considerable decrease in nitrate load removal. Anaerobic conditions were not detected and denitrification was observed even at 5.2 ± 1.2 mg L−1 O2 in influent. Toxicity signs in Vetiveria zizanioides leaves were never detected and the results obtained suggest that the used plant absorbs and assimilates nitrogen from wastewater. Although Vetiveria zizanioides is not commonly used in constructed wetland, it proved to be very a robust, efficient and promoting system, encouraging further studies.
