“…Regarding this, the evaluated species grew rapidly and provided good soil superficial protection, which is a primordial condition to soil conservation. Sutili et al (2018) observed growth rhythms similar to the ones observed in this study to P. sellowianus, S. humboldtiana and G. schottiana species. According to the authors, P. sellowianus, S. humboldtiana and G. schottiana species presented sprouts' length sum of 115 cm, 140 cm and 95 cm, respectively, for cuttings propagated in field experimental seedbed.…”

“…To S. humboldtiana, the same authors affirm that the species present high cutting reproduction capacity, what was confirmed by the excellent result obtained in this study. Sutili et al (2018) report good survival rates to P. sellowianus (100%), S. humboldtiana (96%) and G. schottiana (77%) species vegetatively propagated in field experimental seedbed of cuttings collected during autumn and winter, recommended moment in which the vegetation is in vegetative rest.…”

“…In soil superficial stabilization it is preferable the occurrence of thin roots, once these roots provide higher soil containment and structuring in comparison to thick roots, contributing for superficial soil loss minimization (COPPIN;RICHARDS, 2007). Vertical roots and the ones with thicker diameters are preferable in the cutting's base, what allows best anchoring of soil mass contained by the plant (COPPIN;RICHARDS, 2007;SUTILI et al, 2018). In this way, vertical and thicker roots contribute to higher proportion in depth soil stabilization.…”

The aim of this study was to evaluate the survival rate, the vegetative development and vertical pullout resistance of Phyllanthus sellowianus, Salix humboldtiana, Gymnanthes schottiana, Cephallanthus glabratus and Ludwigia elegans propagated by live cuttings. The experiment was conducted at the Federal University of Santa Maria, RS. The experiment was installed in October 2015 and evaluated in June 2016. Experiment was conducted in randomized blocks design with use of 5 plant species and 3 replications. In each block were planted 3 live cuttings of each species, with the total of 45 cuttings for the 3 blocks. The space between plants was of 1 x 1 m. Live cuttings average diameter was 1.7 cm and 60 cm long. Were evaluated the survival rate, morphological variables from shoots, as well as the vertical pullout resistance for each species. The observed survival rates were: P. sellowianus (100%), S. humboldtiana (100%), G. schottiana (83%), %), C. glabratus (67%) e L. elegans (50%), which are statistically different among themselves by Chi-square test (χ ²) at 5% level of significance. The variables, length and diameter of shoots, as well as the vertical pullout resistance are statistically different between species by Tukey’s test at 5% level of significance, and the best results were observed for P. sellowianus and less favorable to L. elegans. The results showed that the evaluated species, excluding L. elegans, had from great to good survival rates. The species P. sellowianus and L. elegans had the major and minor soil mechanical reinforcement capacity, respectively.Keywords: Soil Bioengineering, land reclamation, soil stabilization, vegetative propagation.

“…According to Sutili et al (2018), auxins are the most used growth regulator, being essential in the rooting process, promoting the formation of roots. The rooting of Eucalyptus sp., Performed by Girijashankar (2012), determined that the application of IBA was the most indicated for vegetative propagation, being the dosage according to the species used.…”

Studies carried out with the use of gliricidia biomass found that green manure contributes to increasing the productivity of forest crops when compared to the incorporation of other legumes. This study aimed to evaluate the viability of vegetative propagation by cuttings in the development of rooting and budding of Glyicidium sepium in different concentrations of indolebutyric acid (IBA). The experiment was carried out in a greenhouse with an entirely randomized block design and increasing concentrations of IBA 0, 625, 1250, and 3000 mg.L-1 with six replicates. The cuttings were standardized in length and diameter, then treated with sodium hypochlorite and immersed in different concentrations of IBA. The parameters plant evaluated were the sprouts number, sprouts length, sprouts diameter, sprouts dry weight, and roots dry weight. The concentration of IBA was shown to be effective in increasing all parameters studied at the IBA concentration of 2100 mg.L-1, and the higher concentrations did not offer any cost-benefit advantages for the production of gliricidia by cutting.

“…A esteira viva deverá ser implantada para revestir uma porção da face do talude, junto ao enrocamento, partindo da linha d'água(ALLEN;LEECH, 1997). A técnica consiste na utilização de ramos vivos das espécies aptas, como Phyllanthus sellowianus úteis, biotecnicamente, para o aumento da diversidade inicial(BARRO, 2011;SUTILI et al, 2018;SUTILI;BRESSAN, 2004). ConformeDenardi et al (2013), a espécie Phyllanthus sellowianus apresenta elevada flexibilidade de seu caule, sendo uma característica importante para obras de bioengenharia em margens de cursos d'água, pois a capacidade de caules e ramos em curvar-se sobre os taludes fluviais, em virtude da força da correnteza durante as cheias, confere maior proteção contra corrosões.…”

O Parque da Lagoa, localizado no baixo curso do Rio Taquari, tem sido um sítio experimental para aplicação de modelos biotécnicos, que visam estabilizar e revegetar taludes fluviais susceptíveis aos processos erosivos. O presente trabalho busca avaliar atributos geotécnicos, ecológicos, econômicos e estéticos de técnicas de engenharia natural implantadas na área do parque no ano de 2010. A partir do diagnóstico destas intervenções biotécnicas, é proposto um projeto de revegetação e estabilização de taludes fluviais com uso das técnicas de bioengenharia, visando mitigar a erosão e ausência de vegetação ciliar que coloca em risco o rompimento da Lagoa Maria Dresch. No decorrer dos anos os modelos biotécnicos aplicados na área do parque adquiriram maturidade ao estabelecer uma vegetação, garantindo estabilidade e proteção às margens do rio. A proposta técnica sugere o uso do material dragado do canal de navegação do rio para remodelagem dos taludes fluviais e a aplicação das técnicas de enrocamento, esteira viva e banqueta vegetada, por serem soluções viáveis com baixo custo e menor impacto ambiental valorizando fatores ecológicos e paisagísticos. A engenharia natural se apresenta como uma alternativa ambientalmente sustentável e os resultados comprovaram sua eficiência como facilitadora para desenvolvimento da vegetação ciliar, e como ferramenta para correção e diminuição dos processos erosivos ao longo dos cursos d’água.
