Citrus budding by shoot apex replacement

This work aimed to verify the setting of small shoot scions of 'Valência' orange tree, inserted on seedlings of five stocks: Rangpur Lime; Citrange 'Troyer'; 'Cleópatra' Mandarin; Trifoliata 'Davis A' and Citrumelo 'Swingle'. The scions consisted of stem apical segments with 2-3 mm thickness. Seventy days after sowing, the stock seedlings were cut, transversely, below the node of the first true leaf at the height ranging from 13,4 to 17,6 mm above the substrate level. The meristematic apices were put on the cut surface of the stocks and fixed with plastic film (Parafilmâ ®). Forty five days after budding, the percentages of selling were: 79%; 67%; 66%, 61% and 34% in 'Rangpur' Lime; 'Troyer'; 'Cleópatra'; Trifoliata 'Davis A' and Citrumelo 'Swingle', respectively. In the same date, the number of leaves emitted by the scions was 3,9 and 2,2 in 'Rangpur' Lime and 'Cleópatra', respectively. Morphological and anatomical aspects of the contact area between scion and stock were documented and described.
