“…However, there was no significative difference on the size of the fruits of 'Okitsu' satsuma mandarin from trees on the different rootstocks (Table 5). The size of the mandarin is an important issue for the growers, as the Brazilian consumers prefer larger fruits (CRUZ et al, 2010). Furthermore, the fruits of 'Okitsu' satsuma mandarin produced by the trees on all rootstocks tested in the present work had acceptable commercial sizes for the Brazilian fresh fruit market, as they could be placed in the 66, 70, and 74 classes (CEAGESP, 2000).…”

In the state of Paraná, 'Rangpur lime' is the main citrus rootstock, which has provided good performance for trees of different cultivars planted in the State. However, rootstock diversification is needed as well as to identify the best ones for citrus cultivars less explored commercially yet. The objective of this study was to evaluate the vegetative growth, yield and fruit quality of 'Okitsu' satsuma mandarin trees (Citrus unshiu Marc.) grafted on nine rootstocks in the Northwest region of the state of Paraná, Brazil.

“…Probably this reduction in total fruit production is due to a reduction in photoassimilates demand in function of lower number of drains in the plant. This can increase the amount of photoassimilates available to the fruits and improve photoassimilates partitioning resulting in higher fruit weight and longitudinal diameter (CRUZ et al, 2010;SILVA et al, 2009).…”

-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...

“…Non-crossover (NC) and crossover (C) GEI were determined according to the Cruz and Castoldi (1991) method. Yield data was subjected to combined analysis of the variance (ANOVA) where accessions and environments were considered as random variables.…”

“…However, crossover GEI causes the lack of correlation among genotypes (Cruz and Regazzi, 1997). Because crossover GEI and environmental effects become the most important source of variation, selection of peach genotypes cannot be accomplished without variation in their performances (Cruz and Castoldi, 1991;Vencovsky and Barriga, 1992). Since peach yield is sensitive to climatic variability because change in temperature and precipitation can alter blooming and fruit development period, we considered those climatic variables to understand the influence of climatic change in peach yield fluctuation.…”
