“…(1995) reports that the used physical protector, a plastic cup of 250 ml, without bottom and with the largest circumference of the circle to the face down, promoted an increase in the tax of germination. Mattei and Rosenthal (2002), notice that protectors as plastic cups and paper cups, without bottom, contributed in the initial emergence and in the establishment of the canafistula seedlings evaluated at 18 months after sowing. Conflicting results were observed by Ferreira et al (2007), in a study with Senna multijuga, observed significant effect for the physical protector, which correspond to transparent plastic pots of 500 ml without bottom, putted above the sowing points.…”

The use of physical protectors has been considered as an efficient technique for tillage farming of different species, mainly native ones. Based on the importance of the species, Peltophorum dubium for revegetation of degraded areas, this study evaluated the emergence, survival and initial development of P. dubium seedlings under the influence of physical protectors with different filters. Thus, the following treatments were adopted: absence of physical protector (APP), transparent physical protector (TPP), transparent physical protector + blue cellophane (BPP) and transparent physical protector + red cellophane (RPP). The evaluated characteristics were: emergence velocity index (EVI), seedling survival and emergence percentage, plant height, leaf area and root collar diameter. All of these physical protectors increased the mean values of EVI and survival. In conclusion, the emergence speed and initial development of P. dubium (Spreng.) seedlings grown in the interior of physical protectors, independent on the filters, presented positive results. The reduction on the light intensity interferes positively in the initial growth of these plants.

“…In this way, the use of physical protectors allowed with direct seedling become relevant, once it can cause the reduction seeds and seedlings predation. Besides, the advantage of its interference in germination and establishment of species created a favorable microenvironment (Ferreira, 2002;Mattei and Rosenthal, 2002).…”

“…A aceleração da germinação de sementes para recobrimento do solo, via semeadura direta em recuperação de áreas degradadas, é imprescindível para que as sementes germinem prontamente e sincronicamente, permitindo uma eficiente implantação de coberturas vivas (MATTEI;ROSENTHAL 2000;SANTOS et al, 2012) Considerando os resultados obtidos, nota-se que as sementes de S. obtusifolia não apresentaram dormência tegumentar. Entretanto, recomenda-se a imersão de suas sementes em água a 75 °C, seguida de embebição por 18 horas, para acelerar o recobrimento do solo através de semeadura direta em projetos comerciais de restauração de áreas degradadas.…”

“…Unlike the condition on the nursery, the lethal agents of the field conditions are not under control (Mattei and Rosenthal, 2002;Woods and Elliot, 2004). Therefore, auxiliary procedures also must be tested, for instance straw and forest litter addition, physical protectors, organic manure supply and weed management.…”

-Direct seeding of native tree species could be a low cost alternative for forest restoration. The paper aimed at evaluate direct seeding of two species from Southern Brazil, Schinus terebinthifolius Raddi and Citharexylum solanaceum Chamisso, comparing with seedling planting. The effects and costs of forest topsoil and forest litter addition were also evaluated in the direct seeding. The experiment was accomplished during 2009/2010. The treatments of direct seeding were CONTROL -control without seeding, TSEED -only seeding, TLITTER-seeding with forest litter cover, TTOPSOIL -seeding with forest topsoil, TBOTH -seeding with forest litter and with forest topsoil, LTCONTROL -control with forest litter and forest topsoil. The species C. solanaceum did not germinate at field. The species S. terebinthifolius had higher germination in the TBOTH, either at 30 days (21.6%) and 360 days (9.0%), which correspond to a density of 9,000 plants · ha-1 after 360 days. The litter singly contributed less to the survival than the forest soil, however a synergic effect between the two inputs was observed. The TBOTH presented a higher growth (42 cm of plant height at 360 days). The costs of direct seeding with inputs (singly or combined) were higher than the conventional seedling planting in relation to the area unity. However, the cost of direct seeding without addition of inputs was higher considering the cost per survivor seedlings. Planted seedling of S. terebinthifolius reached 88.5 cm of height after 360 days. Seedlings of S. terebinthifolius generated by direct seeding reached the average of 5.1 and 42.0 cm of height in the TSEED and TBOTH treatments, respectively. Keywords: Forest restoration; Soil transposition; Financial costs of restoration. AVALIAÇÃO DA SEMEADURA DIRETA DE DUAS ESPÉCIES DE ÁRVORES NEOTROPICAIS COM O USO DE INSUMOS NATURAISRESUMO -A semeadura direta de espécies arbóreas nativas pode ser uma alternativa de baixo custo para a restauração florestal. O trabalho teve como objetivo avaliar a semeadura direta de duas espécies do Sul do Brasil, Schinus terebinthifolius Raddi e Citharexylum solanaceum Chamisso, comparando com um plantio de mudas. Os efeitos e os custos da adição de solo florestal e serapilheira também foram avaliados na semeadura direta. O experimento foi realizado durante 2009/2010. Os tratamentos de semeadura direta foram CONTROL -controle sem semeadura, TSEED -somente semeadura, TLITTER -semeadura com serapilheira, TTOPSOIL -semeadura com solo florestal, TBOTH -semeadura com serapilheira e com solo florestal, LTCONTROL -controle com serapilheira e solo florestal. A espécie C. solanaceum não germinou no campo. A espécie S. terebinthifolius apresentou maior germinação na TBOTH com 30 dias (21,6%) e 360 dias (9,0%), correspondendo a uma densidade de 9.000 plantas/ha aos 360 dias. A semeadura com serapilheira isoladamente contribuiu menos para a sobrevivência do que o solo florestal, no entanto, um efeito sinérgico entre os dois tratamentos foi observado. O TBOTH proporcionou maior cresci...
