“…The soluble solids contents are greater when the flowers are pollinated in Apr., which provides a greater value in the ratio of the fruit, since this represents the ratio between SS/AT. The pH values, titratable acidity and ratio in this study are greater than those found by Silva et al (2011), and the soluble solids contents are similar.…”

Native of the Americas, pitaya is currently a fruit bearing plant in expansion in the domestic and international market and is an alternative source of revenue for small and large farmers. As some studies show the lack of efficiency of natural pollinators in fructification in pitaya, the purpose of this study was to evaluate the efficiency of manual self-pollination and of manual cross pollination in Hylocereus undatus in two periods of pollination. The experiment was carried out in the orchard of the Universidade Federal de Lavras (Federal University of Lavras) in a completely randomized design with a 2 x 2 factorial arrangement (two types of pollination and two flowering periods) with 15 replications, with one flower per replication. The flowers were bagged, emasculated and pollinated manually. The percentage of fruit set , longitudinal and transversal diameter of the fruit, mass of the fruit, pulp and peel, thickness of the peel, soluble solids contents, pH, titratable acidity, ratio (soluble solids:titratable acidity), number of seeds per fruit and seed germination were evaluated. It may be concluded that pollination in red pitaya with its own pollen allows fructification. Flowers pollinated in Apr. result in fruit with physical characteristics superior to the fruit generated by pollination in Jan.

“…According to Chitarra et al [15], fruits in general, when ripe, present mean soluble solid values between 8% and 14%. The literature reports similar values for pitaya-12.51º, 11.87º, 12.23ºBrix [18].…”

Aims: The study objective was to determine the harvest point of red pitaya produced in the north of Minas Gerais, Brazil, according to physical and chemical changes during refrigerated storage. Study Design: The experiment was conducted through a completely randomized design in a 3 x 5 factorial scheme composed of three treatments (ripening stages) and five post-harvest assessment days (0, 5, 10, 15 and 20), with four repeats of four fruits per experimental unit. Study Place and Duration: The experiment was conducted in a cold chamber at the State University of Montes Claros, Brazil, between July and August 2018. Methodology: The following quality parameters were assessed: fruit fresh mass, length and diameter at harvest point, color, firmness, soluble solid content, titratable acidity, total sugars, reducing and non-reducing, pH and amide, during storage. Results: There was no significant difference for fresh mass, length and diameter as a function of ripening stages. Ripening stages 2 and 3 presented higher soluble solid content means. Conclusion: Considering the conditions of northern Minas Gerais, harvest should happen at stages 2 or 3, when fruits have a brighter red hue, that is, are more attractive and of easier identification by producers. In addition, pitayas at these stages have higher soluble solid contents and reduced pulp acidity during storage in relation to fruits harvested at S1.

“…Os cladódios são triangulares, suculentos e constituídos de pequenos espinhos com 2 a 4 mm de largura. A flor é hermafrodita, de coloração branca, antese noturna, e os frutos são externamente vermelhos, com polpa esbranquiçada, de sabor agradável, levemente adocicado, apresentando um grande número de diminutas sementes, de coloração preta (DONADIO, 2009;CAVALLARI, 2011).…”

4RESUMO -Embora tenha ocorrido uma grande expansão do cultivo de pitaia tanto no Brasil como em outros países, a cultura necessita de informações científicas que subsidiem a definição de sistemas de produção, mais adequados às condições edafoclimáticas brasileiras. Diante disso, o presente trabalho visou avaliar o efeito da aplicação do ácido indolbutírico (AIB) e comprimento de estacas no enraizamento de pitaia. O experimento foi conduzido em condições de casa de vegetação. Foram testadas quatro doses de AIB (0; 1.500; 3.000 e 4.500 mg dm -3 de AIB) e dois tamanhos de estacas: pequena (5 a 14 cm) e grande (17 a 26 cm), sendo que os níveis de ambos os fatores foram arranjados em esquema fatorial 4 x 2, com quatro blocos ao acaso. Aos 85 dias da instalação do experimento fez-se a análise fenológica das plantas e a coleta dos cladódios laterais. Avaliaram-se as seguintes características fenológicas: comprimento da maior raiz (CR), massa seca das raízes (MSR), massa fresca da parte aérea (MFPA), massa seca da parte aérea (MSPA), massa seca total (MST), número de cladódios laterais emitidos (NEL), somatório do comprimento dos cladódios (SCC) e razão parte aérea-raiz (RPAR). Ao término do estudo constatou-se que o tamanho das estacas e a aplicação de AIB afetam o enraizamento de pitaia. As plantas propagadas por estacas de tamanho grande (17 a 26 cm), tratadas com 3.000 mg dm -3 de AIB apresentam o melhor enraizamento. Palavras-chave:Pitaia. Plantas-efeito ácido indolbutírico. Plantas-reguladores.ABSTRACT -Although there has been great expansion in the cultivation of pitaya both in Brazil and in other countries, scientific information is needed to help define production systems which are more suited to edaphoclimatic conditions in Brazil. This study therefore aimed to evaluate the effect of the application of indolebutyric acid (IBA) and of the length of cuttings on rooting in the pitaya. The experiment was conducted under greenhouse conditions. Four dosages of IBA were tested (0, 1500, 3000 and 4500 mg dm -3 IBA) and two sizes of cutting: small (5 to 14 cm) and large (17 to 26 cm); levels of both factors being arranged in a 4 x 2 factorial design in four randomised blocks. Eighty-five days after the experiment was set up, a phenological analysis of the plants was carried out, and the lateral cladodes collected. The following phenological characteristics were evaluated: length of the longest root (CR), root dry weight (MSR), shoot fresh weight (MFPA), shoot dry weight (SDM), total dry weight (TDM), number of lateral cladodes issued (NEL), sum of the length of cladodes (SCC) and shoot to root ratio (SRR). At the end of the study it was found that the size of cuttings and the application of IBA affect rooting in the pitaya. Plants propagated from large cuttings (17-26 cm) and treated with 3.000 mg dm -3 IBA show the best rooting.
