摘要：

The objective of this work was to evaluate the efficiency of the in vitro grafting in the propagation of two Eucalyptus urophylla and E. grandis hybrid clones. Juvenile stocks obtained from seeds of E. grandis and E. urophylla germinated in vitro were used. The grafted plants showed success up to 93% at 50 days for the scion and stock combinations. The highest final plant height values were observed when the stock was E. urophylla. Histologic analysis showed that cicatrized callus in the connection region was successfully followed by vascular recomposition in different combinations among scion with rootstocks.
