|Description: ||Alchornea castaneifolia (Willd.) A. Juss. (Urana) is a native species with potential for restoration of riparian vegetation and urban forestry. Given the difficulty of its propagation and the lack of knowledge about their behavior in nursery, this study aimed to evaluate the transposition of Alchornea castaneifolia from natural regeneration as a strategy for saplings production in nursery. The collecting took place in Porto Acre – AC, and selected 120 seedlings, which were divided into three height classes (<10 cm, 10- 15 cm, >15 cm) and cultivated in four substrates (soil, sand, wasting açaí+soil, Plantmax) in a completely randomized design in a 3x4 factorial design. We investigated the survival of seedlings and the growth in sand substrate to the characteristics height (H) and collar diameter (DC), the relationship H/DC, dry mass of shoots, roots and total between the three height classes of the seedlings. The highest percentage of Alchornea castaneifolia seedlings survival was observed in the sand substrate (67%), followed by the wasting açaí+soil substrate (43%). Seedlings that showed greater growth in height, collar diameter and dry mass production were contained in the class above 15 cm in sand substrate. However, the 10-15 cm class of height presented 100% survival of seedlings in sand substrate and also provided high growth. It is therefore recommended the transposition of seedling in the 10-15 cm class using sand substrate for the propagation of Alchornea castaneifolia in nursery. |
