The beneficial effect on yield and quality of `Anna' apple fruits for the application of ascobine at 0.1% and citrine at 0.6% was studied during 1995 and 1996. Results showed that two citrine sprays at start of growth and 30 days later of ascobine at 0.1% or citrine at 0.6% were of material promotion effect on yield, fruit weight, total soluble solids, and total sugars, while reducing the total acidity. Both fertilizers were equally very effective in all the studied characters. The most striking and promising treatment was the application of ascobine at 0.1% or citrine at 0.6% twice during the growing season; i.e., growth start at 30 days later.

This work aims to evaluate the quality of drinking water in the communities of Baiacu, Sao Francisco do Conde, Santo Amaro and Cachoeira. It was verified that in some places of Santo Amaro and Sao Francisco do Conde, from the microbiological point of view, it is not appropriate for consumption, because it was found that the presence of total coliforms in 50% of the samples and that the chlorine content is below the values indicated by the standards in 75% of the analyzed samples. Thus, the consumption of contaminated water can cause diseases, so it is recommended cleaning of residential reservoirs, maintenance in pipes periodically, as well as the need for continuous monitoring of water quality and the intense participation of public agencies in these actions. Through these actions and the active participation of the population, one can preserve the environment and the lives of all those who transit in the communities of the Bay of All Saints

Due to the increase in the consumption of natural products, there has been a growing use and commercialization of bee pollen, thus, the need for a greater quality control regarding the physical-chemical and microbiological characteristics of this product is justified. In this way, the research aimed to determine the physical-chemical, microbiological and sensorial characteristics of four brands of dehydrated pollen, marketed in natural products houses in different parts of the city of Belém-Pará. Microbiological (aerobic mesophilic bacteria, fungi and yeasts, Coliformes at 45°, Salmonella sp and Staphylococcus aureus) and sensorial analyzes were carried out in the physicochemical analyzes (moisture, ashes, lipids, proteins, pH, free acidity, total sugars). The results obtained were within the parameters of quality allowed by the Brazilian legislation for dehydrated pollen. Regarding the microbiological analysis, all brands showed absence of Staphylococus aureus and Salmonella spp. For the sensorial analysis, the C mark presented better results for both flavor and aroma, confirming the quality of the dehydrated pollen commercialized in Belém-Pa.

The use of new technologies is important for the preservation of guava, especially in reaching long-distance markets, being indispensable to associate storage techniques to increase the durability of fresh fruit. We evaluated the efficiency of edible coatings based on agar and Scenedemus sp. on the quality and post-harvest conservation of 'Paluma' guava. The experiment consisted of a randomized design with four replicates. The treatments (T) were composed of mixing concentrations between agar and Scenedesmus sp.: A: (0% + 0%); B: (0% + 0.5%); C: (0% + 1%); D: (0% + 2%); E: (3% + 0%); F: (3% + 0.5%); G: (4% + 0%) and H: (4% + 0.5%) applied by immersion. At the end of 11 days of storage at 10 °C ± 2ºC and 65% ± 5% RH, the fruit was analyzed. There was a significant effect (P < 0.05) of the coating based on Scenedesmus sp. on the brightness (L*) of the peel and pulp of guava, hue (°h) and chromaticity (C*) of the peel, loss of fresh mass, firmness of the pulp, ascorbic acid, titratable acidity, pH, SS/AT ratio, and total sugars. We observed a lower maturation and maintenance of the post-harvest quality of 'Paluma' guava with the active packages corresponding to treatments F and H. This included the maintenance of the indexes L*, C* and h of peel color, retention in the loss of fresh mass, in the firmness and maintenance of organic acids

Abstract Fruits and vegetables are important sources of nutrients for mankind. Among the various fruits available in Bangladesh, mango occupies a vital place in the human nutrition for its delicious taste and higher nutritious value. In this study, five mango varieties, viz. Fazli, Amrupali, Langra, Gopalbogh and Misribogh, were tested to evaluate the quality of these mango varieties available in Northern Bangladesh. Physiochemical characteristics, including moisture, ash, total carbohydrates, total solids, total soluble solids (TSS), pH, acidity, total sugars and ascorbic acid contents were evaluated. The results showed that there were significant (p< 0.05) differences among mangoes of all varieties for physicochemical parameters. In case of proximate composition, the mango variety Amrupali showed the highest ash content (2.34±0.15) and fat content (1.18±0.13). Protein content (0.94±0.12) and total fiber (2.67%) content was shown to be the highest by Gopalbogh and Misribogh, respectively. The selected mango varieties contained TSS of 12.87~20.55oBrix, pH of 4.45~4.67, titrable acidity of 0.07~0.42%, reducing sugar of 8.40~15.43%, non-reducing sugar of 9.24~10.48%, and total sugarof 18.88~25.12%. The study findings would be helpful for the consumers, dietitian and industry policymakers.

Combinations of 3 methods of controlling tree size (use of the growth retardant paclobutrazol, postharvest topping, and autumn cincturing) were evaluated for their effects on growth, yield, and fruit quality of the low chill nectarine cv. Sundowner in subtropical Australia. Compared with controls over 3 seasons, paclobutrazol used alone reduced tree size by 34-52%, with further reductions when combined with light and severe postharvest topping (by 5-25 and 58-71%, respectively). Yield efficiency (as measured by yield per unit canopy volume) was significantly improved by paclobutrazol and was doubled when paclobutrazol was combined with severe postharvest topping. Although this combination reduced time associated with pruning, thinning, and harvesting, it had the disadvantage of delaying flowering and, consequently, fruit maturity in the subsequent harvest season. Light postharvest topping and autumn cincturing used with paclobutrazol had little effect on yield efficiency, fruit quality, or harvest period. The seasonal pattern of starch reserves for twigs was similar for all treatments, with starch levels falling to a minimum during the early harvest period. Measurements of starch in the major tree organs showed that at very low harvest increments (<10) there was little or no depletion of starch from the twigs and leaves, but as harvest increments increased (range 10-40), there was increasing starch depletion, in order of priority, from the roots, trunks, and limbs.
