Anthracnose is an important foliar and fruit disease of passion fruit, Passiflora spp. (3). In 2008, postharvest anthracnose on purple and yellow passion fruits (P. edulis Sims and P. edulis f. flavicarpa O. Degner, respectively) from a commercial planting in Miami-Dade County, FL was examined. Lesions began as light brown areas that became papery, covered much of the fruit surface, and developed pink-to-dark sporulation. Single-conidium isolates from lesions were examined morphologically and with internal transcribed spacer (ITS) sequences. Four taxa were identified: Colletotrichum boninense (GenBank No. GU045516) with felted cream-to-orange colonies and cylindrical conidia; C. capsici (synonym C. truncatum [2]) (GU045515) with sparse, white mycelia, setose acervuli, and falcate conidia; C. gloeosporioides with fluffy white-to-gray colonies and straight, cylindrical conidia; and a Glomerella sp. (GU045517) with darkly pigmented perithecia. In two experiments, four mature, yellow passion fruit were wounded at a single equatorial site with a sterile needle and inoculated with a 15-μl drop of 0.3% water agar that did not contain (noninoculated control) or contained 105 conidia per ml of representative isolates from each taxon. After 21 days at 25°C without light, anthracnose incidence was recorded and the presence of the isolates was confirmed by their recovery from lesion margins on potato dextrose agar. Anthracnose did not develop on noninoculated control fruit. Mean incidences of anthracnose exceeded 50% for isolates of C. boninense (three from passion fruit), C. capsici (two from passion fruit), and a Glomerella sp. (two from passion fruit and one each from papaya and eugenia). Despite its common indictment as a causal agent of anthracnose on passion fruit (3), symptoms developed on only one fruit that was inoculated with an isolate of C. gloeosporioides from passion fruit (13%) and did not develop after inoculation with an isolate from papaya. Work is needed to determine whether host-specific populations of C. gloeosporioides exist on passion fruit that were not assessed during this study or whether the pathogen was misidentified in previous reports on this host. C. boninense was associated previously with postharvest anthracnose of passion fruit in Japan and Colombia, whereas C. capsici was associated with leaf anthracnose of passion fruit in Florida and Japan (4); both species are reported here for the first time as causes of postharvest anthracnose of passion fruit in Florida. Glomerella sp. caused darkly pigmented lesions and produced the teleomorph on symptomatic passion fruit and in single-ascospore cultures. Isolates with ITS sequences that are 99% homologous to those from passion fruit have been recovered in South Florida from eugenia, papaya, and Piper betle (4) and from other locations on several other hosts (GenBank); they are often nonpathogenic endophytes. Almeida and Coêlho (1) reported in Brazil a Glomerella sp. that formed the teleomorph in culture and caused anthracnose on passion fruit, but did not provide ITS sequences. Additional work is warranted on the identity and ecology of these fungi. References: (1) L. C. C. Almeida and R. S. B. Coêlho. Fitopatol. Bras. 32:318, 2007. (2) U. Damm et al.

ABSTRACT: The aim of this research was to determine the sample size needed to estimate the average of wild passion fruit ( Passiflora caerulea ) traits. It was collected randomly, 133, 99 and 133 fruit of wild passion fruit in 30, 21 and 29 plants, located respectively, in the cities of São Borja, Itaqui and Uruguaiana, on the west border of Rio Grande do Sul, Brazil, totaling 365 fruits harvested in 80 plants. In each fruit were measured ten traits: width, length, fruit, skin, and pulp weight, pulp yield, luminosity and tone of skin and pulp. Then, central tendency, dispersion and distribution measures were calculated and the normality of the data checked. After, it was determined the sample size needed to estimate the average for each character, assuming estimation errors equal to 1, 2, ..., 10% of the mean estimate with confidence levels of 95% and 99%. In wild passion fruit, 12 fruits are sufficient to estimate the mean of luminosity and tone of the skin and pulp, with an estimation error of 5% of the mean and 95% confidence, regardless of the evaluation location (São Borja, Itaqui or Uruguaiana). In this same level of accuracy 36 fruits are needed to estimate the width and length, 52 fruits to estimate the pulp yield and 319 fruits for the evaluation of the fruit, skin and pulp weight.

The aim of this study was to develop a goat's milk-based yogurt with a layer of tamarind and passion fruit jelly on the bottom of the package (bilayer yogurt) as well as to carry out the physical-chemical, microbiological and sensory characterization. of product. For comparison purposes, goat's milk products were compared with the same cow's milk product. The physicochemical analyzes showed that the samples are within the standards of the legislation, both for yogurts and jams. Regarding microbiological analyzes, there was no microbial growth in any of the samples evaluated. Sensory tests were carried out with 60 tasters that were aged between 14 and 32 years. Sensory attributes related to “appearance”, “color”, “aroma”, “consistency” and “flavor” were evaluated, among them only consistency showed a significant difference due to the chemical characteristics of goat's milk, however, in percentage values goat's milk yogurt was rated with the highest grades. In the global impression and purchase intention, the analysis of the data obtained showed that the values attributed by the tasters are located in the highest scores of the hedonic scale. Thus, for bilayer goat's milk yogurts with tamarind or wild passion fruit jams, the results are favorable and highly acceptable. These results denote the possibility of insertion of these new products in the regional market in view of the acceptance of the product by the tasters as well as the intention to purchase, in addition to the appreciation of the regional fruits present in the jams elaborated.
