Resumo: O cultivo de pitaia vem sendo cada vez mais valorizado no mercado interno brasileiro, devido suas características de rusticidade, elevado valor de comercialização, produção precoce e ganhos por área cultivada, porém, a cultura ainda carece de pesquisas relacionadas ao seu método de propagação. A enxertia é uma técnica amplamente utilizada na fruticultura e possui muitos benefícios, como a possibilidade de utilização de porta-enxertos com bom enraizamento e resistentes às doenças, quebra do período juvenil da planta e a substituição de cultivares. Nesse contexto, objetivou-se com este trabalho estudar o pegamento da enxertia e o crescimento do enxerto utilizando diferentes variedades copasenxertos e porta-enxertos de pitaia. O experimento foi instalado no município de Ingaí-MG, na propriedade rural denominada Serra da Soca, com duas variedades de porta-enxerto Cebra e Orejona e cinco variedades de copas American Beauty, Golden, Dark Star, Vietnamese White e Physical Graffiti. Foi utilizada a enxertia por sub
Abstract: Dragon fruit cultivation has been Dragon fruit cultivation has been increasingly valued in the Brazilian domestic market, due to its rustic characteristics, high commercial value, early production and gains per cultivated area, however, the culture still lacks research related to its propagation method. Grafting is a technique widely used in fruit growing and has many benefits, such as the possibility of using rootstocks with good rooting and resistant to diseases, breaking the plants juvenile period and replacing cultivars. In this context, the objective of this work was to study the graft setting and graft growth using different varieties of dragon fruit sciongrafts and rootstocks. The experiment was installed in the municipality of Ingaí-MG, on the rural property called Serra da Soca, with two varieties of rootstock Cebra and Orejona and five varieties of scion American Beauty, Golden, Dark Star, Vietnamese White and Physical Graffiti. Bud replacement grafting was used, thus, the rootstocks were pruned keeping only one cladode segment, without side branches, then the tip cladode was twisted, removing it and leaving the vascular cambium exposed along with it. with the central woody part where a bevel cut was made, this woody part served as support and fitting for the graft using a tape to secure the graft to the rootstock. The experimental design was in randomized blocks (DBC), in a 2 x 5 factorial (rootstocks x grafts) with two plants per plot and 5 replications each. The parameters evaluated were percentage of graft take, percentage of living grafts and length of grafts at 54, 78, 131 and 181 days after grafting. Data on graft percentage and average graft length at 188 days after grafting were subjected to analysis of variance and the means were compared using the Tukey test at a 5 probability level. To evaluate the percentage of living grafts, descriptive statistics were used using column graphs, prepared in the Microsoft Excel program. The rootstock influences the percentage of grafting and length of grafts in different varieties of dragon fruit. The Orejona variety has a higher payment percentage for the Physical Graffiti and Vietnamese White varieties. The varieties Physical Graffiti, American Beauty and Golden showed greater average graft length on the Orejona rootstock. It is concluded that grafting is a viable practice, enabling the production of new dragon fruit seedlings, requiring further studies regarding plant development and fruit production. valued in the Brazilian domestic market, due to its rustic characteristics, high commercial value, early production and gains per cultivated area, however, the culture still lacks research related to its propagation method.
