“…Conversely, the plants that were not treated with humic substances presented an exponential decay with the increasing nitrogen levels ( Figure 2D). The reduction of fruit soluble solids as a function of an increasing nitrogen level was previously reported by Silva et al (2002), and this reduction could be explained by the positive and direct effect of humic substances on the root absorption of ammonium nitrate (KEELING et al, 2003).…”

ABSTRACT. The custard apple (Annona squamosa L.), also known as the sugar apple, is a fruit species native to Brazil that has been poorly studied, especially in relation to the effect of humic substances on its fruit quality and yield. An experiment was conducted from December 2010 to November 2011 to evaluate the fruit quality and yield of the custard apple as a function of nitrogen fertilising and the use of humic substances. The experimental design consisted of randomised blocks, with treatments distributed in a factorial arrangement (4 x 2), using four nitrogen doses (0, 100, 175 and 250 g of N plant -1 ) and two humic substance applications (with and without humic substances), with four replications. The fruit yield and fruit characteristics, such as fruit mass, titratable acidity (TA), soluble solids (SS), pulp pH and SS/TA ratio, were recorded. The humic substances and the nitrogen levels significantly affected the soluble solids, titratable acidity and SS/TA ratio, while the pH pulp was only influenced by the humic substances. The humic substances promoted a quantitative increase in the fruit yield of 0.63 ton ha -1 . The fruit quality and yield of the custard apple depend on the nitrogen fertiliser and the interaction of the humic substances. Nitrogen fertilising of 100 g per plant, associated with humic substances, could be recommended for use in the production of custard apples.

“…In general, it represents a measure of the concentration of sugars and other solids diluted in juice or pulp of the fruit and is considered an indicator of quality since it provides data on the organoleptic characteristics of fruits (Silva et al, 2002;Leão et. al., 2006).…”

The Physalis genus includes species with nutraceutical uses and is typically identified by morphological characteristics. In Brazil and the world, the best-known species are P. angulata, P. peruviana and P. ixocarpa emerging more in the production of fruit used for various purposes. In this scenario, the physicochemical characteristics of mature fruits and seeds, are extremely important, especially for commercial purposes as well as the separation and identification of promising genotypes. Biometric analysis of ripe fruit, measuring the o Brix, seed analyses were performed and compared four potential species Physalis grown in Feira de Santana, Bahia, Brazil. Principal component analysis showed two of the ten analyzed characteristics that represent about 98% of the total variance observed between species, namely: °Brix and E15 (Emergency in 15 days after sowing). P. ixocarpa fruit stood out in relation to other species, reaching the highest average for the biometric data.

Fruit physico-chemical characteristics of two species of pitayaThe objective of this study was to evaluate physical and chemical characteristics of the fruits of 21 accessions of two pitaya species, Hylocereus undatus and Selenicereus setaceus. The experiments were arranged in a completely randomized design with four replications. Each replication consisted of 3 fruits. The characteristics length, diameter, soluble solids, skin and pulp total mass were analyzed. Soluble solids were determined in the homogenized pulp and at three different points inside the pulp. Analyses of variance were performed with the Genes software and means were compared using the Scott and Knott test. Pearson correlation coefficients between different traits were determined. H. undatus genotypes 02 and 05 stand out due to their larger length, diameter and fruit weight compared with the other genotypes. The species S. setaceus had higher soluble solids content in fruit pulp, differing significantly from H. undatus. High heritability and CVg values were found for the physical characteristics of pitaya fruit. These parameters are important to determine selection strategies and to estimate the genetic gain. The correlations indicated that genotypes with larger fruit size and mass have less soluble solid content in the pulp. O objetivo deste trabalho foi avaliar características físico-químicas dos frutos de 21 acessos de duas espécies de pitaya, Hylocereus undatus e Selenicereus setaceus. Foi utilizado um delineamento inteiramente ao acaso, com quatro repetições, sendo cada repetição a média de três frutos. Foram analisados comprimento e diâmetro dos frutos, sólidos solúveis, massa total da casca e da polpa dos frutos. As análises de variância foram realizadas por meio do programa Genes e as médias foram comparadas pelo teste Scott e Knott, a 5% de significância. Foram determinados os coeficientes de correlação de Pearson entre as diferentes características analisadas. Os acessos 02 e 05 da espécie H. undatus destacam-se por apresentarem maiores comprimento, diâmetro e massa dos frutos, comparando com os dos demais acessos. A espécie S. setaceus apresenta maior teor de sólidos solúveis da polpa dos frutos, diferenciando-se significativamente da espécie H. undatus. Altos valores foram encontrados para herdabilidade e CVg, para as características físicas dos frutos de pitaya, estimativas importantes para se determinarem estratégias de seleção e para se estimar o ganho genético. Os resultados das correlações indicam que quanto maior o tamanho e a massa, menor é o teor de sólidos solúveis na polpa dos frutos de pitaya.
