“…Research and use of new passion fruit cultivars, such as the new 270 series intravarietal hybrids, produced by breeding program of "Instituto Agronômico de Campinas" (IAC) and BRS Sol do Cerrado, BRS Gigante Amarelo and BRS Ouro Vermelho cultivars from Embrapa breeding program (MELETTI, 2011) have been increased potential yield, fruit quality and resistance or tolerance to diseases and pests. However, there are few studies with these new passion fruit cultivars under irrigated conditions in the semiarid region, aiming to increase yield and fruit quality.…”

-Studies with nitrogen and potassium in yellow passion fruit cultivars with high yield potential are scarce in semiarid regions. The aim of this study was to evaluate the influence the N and K doses on productivity and fruit quality of different passion fruit cultivars in irrigated conditions in the northern of Minas Gerais state. The study was installed at experimental farm located in Janaúba-MG. This area was located at 15º 47' S and 43º 18' W, 516 m above sea level. The experiment was in completely randomized block with four replications, arranged in 4 x 6 factorial design consisting of four Passion Fruit cultivars (BRS Sol do Cerrado, BRS Ouro Vermelho, BRS Gigante Amarelo, IAC 275) and six N and K doses, which corresponded to 0-0, 50-125, 100-250, 150-375, 200 -500 and 250-625 kg ha -1 yr -1 of N and K 2 O, respectively. BRS Gigante Amarelo and BRS Sol do Cerrado cultivars showed higher productivity. Total fruit yield and average fruit weight were higher for BRS Sol do Cerrado and IAC 275, BRS Gigante Amarelo and BRS Ouro Vermelho cultivars, respectively. IAC 275 showed the highest pulp yield and along with BRS Sol do Cerrado, showed the higher soluble solids/titratable acidity ratio. BRS Sol do Cerrado, BRS Gigante Amarelo and IAC 275 cultivars showed higher pulp productivity, indicating that they are more promising for passion fruit juice industry.

PRODUÇÃO E QUALIDADE DE FRUTOS DE MARACUJAZEIROS APÓS A ADUBAÇÃO COM NITROGÊNIO E POTÁSSIORESUMO -Estudos com doses de nitrogênio e potássio em cultivares de maracujazeiro amarelo com alto potencial produtivo são escassos nas regiões semiáridas. Objetivou-se avaliar a influência das doses de N e K na produtividade e qualidade de frutos de diferentes cultivares de maracujazeiro irrigado, na região norte do Estado de Minas Gerais. O estudo foi instalado no município de Janaúba-MG e seguiu o delineamento em blocos casualizados, com quatro repetições, sendo as unidades experimentais arranjadas em esquema fatorial 4 x 6 consistindo de quatro cultivares de maracujazeiro (BRS Sol do Cerrado, BRS Ouro Vermelho, BRS Gigante Amarelo, IAC 275) e seis doses de N e K, correspondentes a 0-0, 50-125, 100-250, 150-375, 200-500 e 250-625 kg ha -1 ano -1 de N e K 2 O, respectivamente. O diâmetro médio do fruto, teor de sólidos solúveis, acidez titulável, pH e coloração dos frutos não apresentam diferença entre as cultivares estudadas e doses utilizadas de N e K. As cultivares BRS Gigante Amarelo e BRS Sol do Cerrado obtiveram maior produtividade. A produção total de frutos por hectare e o peso médio dos frutos foram superiores nas cultivares BRS Sol do Cerrado e IAC 275, BRS Gigante Amarelo e BRS Ouro vermelho, respectivamente. A cultivar IAC 275 teve maior rendimento em polpa e juntamente com a BRS Sol do Cerrado apresentaram maiores relações sólidos solúveis/acidez titulável. As cultivares BRS Sol do Cerrado, BRS Gigante Amarelo e IAC 275 tiveram maior produtividade de polpa, ind...

“…The number of commercial passion fruit cultivars is small, considering the great variability of agroecosystems in Brazil. Commercial passion fruit cultivars available in Brazil are the 270 series intravarietal hybrids developed by the Agronomic Institute of Campinas, the hybrids developed by the Brazilian Agricultural Research Company -Embrapa Cerrados, and the Flora Brasil series cultivars (MELETTI, 2011). however, among passion fruit cultivars available in the market, none of them was developed for cultivation in the State of Mato Grosso.…”

-The productivity and physicochemical quality evaluation is important, as it identifies superior populations. however, launching products requires following the descriptors according to DhE test instructions. Thus, this study aimed to evaluate three passion fruit populations with high productivity and physicochemical quality characteristics for commercial launch. The experiment was conducted at the State University of Mato Grosso experimental area, located in the municipality of Tangará da Serra, MT. The experimental design was complete randomized block design with four replicates and ten plants per plot. The physicochemical characteristics were submitted to analysis of variance and compared by the Tukey test. For the distinctiveness test, 25 descriptors were evaluated, where quantitative data have been converted into multicategoric data to obtain the dissimilarity matrix. From the dissimilarity matrix, groups were formed using the Tocher and UPGMA methods, Livestock and Supply Department. The highest productivity and number of fruits were verified for BRS Rubi Cerrado cultivar and UNEMAT S10 population. Populations and cultivars presented physicochemical characteristics that meet the required quality for both fresh consumption and industry use. Based on the distinction test among genotype, it was observed that the descriptors were effective for population differentiation. UNEMAT S10 population has characteristics that distinguish it from other cultivars and populations evaluated, and presents high agronomic performance; therefore, it can be launched as a commercial cultivar. Index terms: Commercial launch, Descriptors, Passiflora edulis Sims. PRODUTIVIDADE, QUALIDADE FÍSICO-QUÍMICA DE FRUTOS E DISTINGUIBILIDADE DE POPULAÇÕES DE MARACUJAZEIRO-AZEDORESUMO -A avaliação da produtividade e da qualidade físico-química apresenta importância, pois permite identificar populações superiores. Porém, para lançar material, é necessário seguir os descritores conforme as instruções para a execução dos ensaios de DHE. Desta maneira, objetivou-se avaliar três populações de maracujazeiro-azedo que apresentem características de alta produtividade e qualidade físico-química, para lançamento comercial. O experimento foi conduzido na área experimental da Universidade do Estado de Mato Grosso, situada no município de Tangará da Serra-MT. O delineamento experimental foi o de blocos completos casualizados, com quatro repetições e dez plantas por parcela. As características físico-químicas foram submetidas à análise de variância e comparadas pelo teste de Tukey. Para avaliar a distinguibilidade, foram utilizados 25 descritores, onde os dados quantitativos foram convertidos em multicategóricos, visando a obter matriz de dissimilaridade. A partir da matriz de dissimilaridade, formaram-se grupos pelo método de Tocher e UPGMA. A maior produtividade e o maior número de frutos foram verificados na cultivar BRS Rubi do Cerrado e na população UNEMAT S10. As populações e as cultivares apresentaram características físico-químicas que ate...

“…The wild species of Passiflora have characteristics of interest to passion fruit culture, including longevity, adaptation to adverse weather conditions, extended flowering period, higher concentration of chemicals of interest to pharmaceutical and cosmetic industries and resistance to diseases (Meletti, 2011). The latter is one of the main goals of passion fruit breeding programs (Junqueira et al, 2006).…”
