Qualidade de sementes de feijão de diversas densidades obtidas na mesa gravitacional

Calendula (Calendula officinalis L.) is a plant with medicinal properties used in phytotherapic production and in the cosmetic industry. Seed is the basic input, so requirements of physiological quality to guarantee the establishment of cultivations with high productivity is essencial. Four lots were used with different origins and storage times of storage to evaluate the efficiency of methods that allow separation of lots of calendula seeds in vigor levels. The lots were evaluated using germination test, seed moisture content, seed dry matter weight, weight of 1000 seeds, first count of the germination test, emission of primary root, electrical conductivity, seedling emergence, speed of seedling emergence, seedling length, seedling green matter and dry matter weight. The tests of first count of the germination, emission of the primary root, and speed of seedling emergence index allowed the separation of the lots in vigor levels. The combination of the information supplied by the comparison of averages and for the correlation analysis between different vigor test and seedling emergency facilitates better evaluation of the seed quality.The performance of IAC-Carioca SH bean seeds, after they have been submitted to the classification processes by sieves and separation by density in the gravitational table, were evaluated in relation to the physiologic and sanitary quality of the seeds, contained in three fractions of discharge of the gravitational table. The vigor test was not influenced by the size of the seed and its acting is related to the degree of humidity. Higher density seeds could be stored for twelve months with small loss of their germination percentage without compromising the stand. Seeds of medium density retained in the sieves 10, 12 and 13 and stored until the tenth month can be used as seed. Seeds with lower density, are not recommended for planting and they present larger index of contamination by field fungi. Seed contamination by storage fungi Aspergillus spp. and Penicillium spp., was directly related to the relative humidity of the storage facility.Calendula (Calendula officinalis L.) is a plant with medicinal properties used in phytotherapic production and in the cosmetic industry.

Qualidade pós-colheita de cerejas cv. Ambrunés utilizando coberturas comestíveis

The objective of this study was evaluate the quality of cherries cv Ambrunes (cherries perforated) covered with edible coatings based on zeina and carnauba wax emulsion, appliied in the form of immersion and pulverization and storage in controlled environment with temperature 5 oC ± 0,5 oC and humidity 90 - 95 %. The parameters used to evaluate the quality of the fruits were: soluble solid, titratable acidity, loss of weight, soluble solid relation / titratable total acidity and fungal deterioration. The fruits were evaluated until the 52nd day of conservation. The treatment that used the emulsion carnauba wax was superior in all of the parameters when compared with the control fruits and the fruits coatings with zeina. The coating based on zeina provoked an acceleration in the ripening of the fruits and presented fungal deterioration since the 24th day storage. It was also noticed that this form of cherries without the peduncle (cherries perforated) commercialization, represents a bigger possibility of fungal contamination trought the injured area. The emulsion of carnauba wax retarded the deterioration until the 45th day of conservation, showed while the better treatment.

Avaliação de linhas de beneficiamento e padrões de classificação para tomate de mesa

ABSTRACT Evaluation of packing lines and classification standards forfresh market tomatoes in BrazilCurrently, are available in the Brazilian market some alternativesof packing and standardization equipment for fresh market tomatoes.The most common ones classify the fruits through their size andweight. Five packing line units for classifying fresh market tomatoes,located in the Campinas region, Brazil, were evaluated. The type ofequipment was characterized; the involved steps in the process, andthe working functions were analysed. A comparison was donebetween the classification recommended by the Brazilian Programfor the Modernization of the Horticulture (developed by theCEAGESP), and those used in the different packing housesevalkuated. The classification was carried out measuring thetransversal diameter of the fruits with a digital paquimeter. A largevariation was observed (99%) in the length of the packing lines. Inthe washing step the number of brushes varied from 4 to 19 nylonbrushes. In the drying step, the number of foam brushes(polyurethane-polyether) ranged from 5 to 15, and from 6 to 64brushes of animal origin (horse poil mainly) in the second dryingand polishing step. For bigger classification standards a lack offulfillment of the norms was observed. From the 14 samples takenin the 5 packing houses, only 57.2% worked accordingly to therecommended norms.Keywords: Lycopersicon esculentum Mill, brushes, packing houses,standards.
