Container sizes and the use of hydrogel in the establishment of seedlings of native forest species

This study evaluated survival and early growth of 30 native species, planted in the containers tubetão (290 cm³), tubetinho (56 cm³), and bandeja (9 cm³), with and without use of hydrogel at planting. The species contemplated all successional groups and 17 botanical families. As a result, we concluded that the species from tubetão had lower percentages of mortality, followed by tubetinho and bandeja. Some species produced in bandeja showed lower mortality, when compared to those of tubetinhos, showing the possibility of its use, with managements that ensure the initial survival of the seedlings. The hydrogel did not affect the establishment and growth of seedlings, in all containers. We concluded that ensuring the establishment of seedlings, there were no differences between containers, stressing that different managements might reduce costs in the restoration with total planting.
