RESUMO
The demand for ecological restorations project, using total planting techniques, has increased in recent years, with the consequent optimizations need of inputs for such activity that, besides increasing the seedlings survival in the field, is essential for the sector. Thus, environmental compensation, generated by the work of the southern section of the Rodoanel Mário Covas (São. Paulo), provided a valuable opportunity to conduct some studies in this area. This studys aim was to evaluate the survival rate and early growth (12 months) of 30 native species from plants in containers packed with three separate volumes (290 cm3 tubetão, tubetinho 56 cm3 and bandeja 9 cm3), with and without hydrogels use at planting, and subordinated to the same maintenance actions. The regional native species, contemplated at all successional groups (pioneer and non-pioneer), belonging to 17 botany families. As a result of this work, we can conclude that species from the container tubetão had the lowest percentage of mortality, followed by tubetinho and bandeja, however some bandeja species have come out with lower mortality rates, compared to other species from tubetinhos, thus presenting use opportunities since different management are adopted (irrigation after planting and control of competitors) in order to guarantee the increase of initial survival of seedlings. The hydrogel did not affect the establishment and neither the growth of seedlings in different containers, during the period in which the experiment was evaluated. Concerning the seedlings development in growth and increase in height, one can conclude that once guaranteed the seedlings establishment of, there were no differences between the containers, reinforcing that with different managements, the restoration costs may be significantly reduced for situations that require the total planting as a methodology in ecological restoration of a given area.
