The purpose of seed conditioning process is to separate seeds and their associated structures into different fractions and retain only good and healthy seeds. Thus, the aim of this study was to evaluate the effects the stages of seed conditioning have on the sanitary quality of marandu grass seeds. The seeds were sampled before and during the seed conditioning process, i.e., after exiting the air-screen cleaner and sieves (seeds discharged from the top, middle and bottom sieves), the first gravity separator (seeds drifting around the table, upper and intermediate discharge) and second gravity separator (upper, intermediate and lower discharge). The sanitary analysis was performed using the filter paper method with and without surface disinfestation of the seeds, which were incubated at 20±2°C, with a photoperiod of 12 hours for seven days. The experiment was conducted in a completely randomized design, in a 2x6 factorial scheme (surface disinfestation x stages of the seed conditioning process) and ten replications. The data was submitted to analysis of variance, using the F test and, when significant, the means of the treatments were compared using the Tukey test at 5% probability. It was concluded that it is not possible to improve the sanitary quality of marandú grass seeds through the seed conditioning process.

This study aimed at evaluating the internal and external quality of brown-shelled eggs commercialized in the municipality of Parintins-AM. A total of 540 eggs were evaluated and distributed in a completely randomized design, which consisted of three treatments and six replications of 30 eggs each. The treatments were: eggs sold in supermarkets; in grocery stores; and eggs sold directly at the farm. The age of the eggs from supermarkets and grocery stores was unknown, however, the eggs bought at the farm were marketed as being from the day of laying. The collected data were submitted to analysis of variance and Tukey test at 5% probability. There were no differences (p > 0.05) of treatments in the percentage of dirty eggs, however, grocery and farm eggs presented higher (p < 0.05) crack percentage. The eggs at the farm presented higher incidence (p < 0.05) of internal stains of blood. The weight of the egg and albumen presented no differences (p > 0.05). However, the albumen percentage of the farm eggs was higher than the other treatments (p < 0.05). The percentages for yolk and eggshell weight from the farm eggs were lower than the supermarket and grocery eggs (p < 0.05). For the variables albumen height, Haugh unit, albumen index, yolk and albumen pH, the best results were observed for the farm eggs, however, regarding these variables, eggs sold in supermarkets and grocery stores did not differ from each other.  The brown shell eggs sold in the city of Parintins/AM have high rates of external defects, and the eggs bought directly from the farm presented better internal quality, when compared to eggs sold in different establishments.

The objectives of the study were (1) to know there was or no interaction between soaking time in bay leaf and type of carcass to the physical quality of broiler meat; (2) To know the duration of optimum immersion for the physical quality of the muscles of the breast and thighs. This research was arranged using Completely Randomized Design (RAL) with factorial pattern. The first factor is the length of meat immersion in bay leaf solution, namely: P0: control; P1 (20 minutes); P2 (40 minutes); P3 (60 minutes). While the second factor is a piece of carcass, namely: K1 (thigh) and K2 (chest). Each treatment was repeated 3 times. The research variables were pH of meat, WHC, and cooking loss. The data obtained were proceed to variance analyze and further tested by BNT  Test for length of  immersion and Tukey test for carcass type at 5% level of significant. The results showed that there was no interaction (P>0,05) between soaking time and carcass cut. The duration of immersion had no significant (P>0,05) effect on pH, WHC, and cooking loss. Carcasses cut of thight and breast have a significant effect (P<0,05) on pH and cooking loss, but are not significant (P>0,05) for WHC. The pH value of the thigh meat is significantly (P<0,5) higher than the breast, but the cooking loss is lower. Keywords :  Bay Leaf, Breast, Thight, Broiler, Physical Quality

The aim of this study was to evaluate the changes in quality of fruits of two species of physalis (P. angulata and P. pubescens) harvested from family farmer orchards in different maturity stages, comparing with fully ripen fruits to those of the commercial species (P. peruviana) of similar maturity. The experiment was conducted in a completely randomized design, in five maturity stages for P. angulata and in four for P. pubescens. Data were submitted to variance analysis and means of the maturity stages compared by the Tukey test at 5 % probability. For the comparison of fully ripen fruits of P. peruviana with the two species produced in different locations were used six replications and the means compared by Dunnett's test at 5 % probability. The fruit diameter varied from 15.1 to 18.0 mm that classifies it as of caliber B. During maturation the color of the fruit evolved from green to totally yellow (P. angulata) and to yellow-brown with purplish features (P. pubescens). The soluble solids (SS) contents of the fruits of P. angulata were superior to those of P. pubescens and the commercial species. Comparing with commercial species, the SS/AT ratio was higher in locally produced fruits, indicating more palatable fruits. Fruits of P. angulata present favorable characteristics for fresh consumption, with potential for extensive cultivation and trade in family horticulture.

The evaluation of the physiological potential of sweet corn seeds is fundamental in the production process, because the germination and vigor reflect the potential for storage, commercialization and use of these seeds. The choice of vigor tests with an adequate and efficient analysis methodology is fundamental to obtaining reliable results. In this sense, the objective of this study was to assess the physiological potential of sweet corn seeds after hydration using different moistening methods to increase water content to 20%. First, the lot of seeds was characterized as to its moisture content and initial physiological potential. Subsequently, two experiments were conducted, both under a completely randomized design. In the first experiment, different volumes of water on the filter paper sheets were assessed for seed hydration a method that uses a wet substrate. In the second, four hydration methods were evaluated: wet substrate (WS), humid atmosphere (HU), immersion in water (IW) and addition of the required amount of water (WR). A constant temperature of 25ºC was used in both experiments and then the moisture content and physiological potential of seeds were determined. The humid atmosphere method reduces the physiological quality of sweet corn seeds because it favors the deterioration and hence is unsuitable for the hydration of seeds of this species. The wet substrate method, in an amount equivalent to 2.5 times the paper mass, increased the water content of sweet corn seeds to 20%, achieving the desired degree of moisture without altering their physiological potential.

This study aimed to evaluate the effect of nitrate salts and a growth regulator on seed conditioning. Subsequently, the responses of the influence of the leaf application of paclobutrazol (PBZ) and nitrogen on the quality of seedlings of Capsicum frutescens L. were evaluated. Two experiments were carried out. The first experiment was conducted in a completely randomized design to evaluate priming, as follows: T1 – control, T2 – control (water), T3 – 0.2% calcium nitrate, T4 – 0.2% potassium nitrate, T5 – 0.1% calcium nitrate + 0.1% potassium nitrate, T6 – PBZ, and T7 – PBZ + 0.1% calcium nitrate + 0.1% potassium nitrate. The second experiment was carried out in a completely randomized design in a 2×5 factorial scheme consisting of priming (absence and presence of calcium nitrate) and leaf application of growth regulator, as follows: control (water), PBZ, PBZ + 1% nitrogen (calcium nitrate), PBZ + 1% nitrogen (urea), and PBZ + nitrogen (0.5% calcium nitrate + 0.5% urea). Physiological conditioning with a solution of 0.1% calcium nitrate increased the germination and seedling emergence rate and resulted in seedlings with a higher shoot length at 33 days after sowing (DAS), but seedlings at 50 DAS showed no differences in growth with its use. Leaf application of 0.1% paclobutrazol provided pepper (C. frutescens L.) seedlings with better distribution in growth according to the Dickson quality index.

This work aimed to characterize physically and physiologically buffelgrass seeds collected in different municipalities located in the semiarid region of Bahia and at different positions in the panicle. At each site, two hundred mature, whole panicles were collected when seeds were naturally falling. A 5 &times; 3 factorial in a completely randomized design was used. Factors were five municipalities where seeds were collected and three positions within the panicle (bottom, middle and top portions), with four replicates of 50 seeds for each treatment. Moisture content, dry seed weight, electrical conductivity, germination percentage, germination speed index and emergence speed index were assessed. Data were tested by analysis of variance and Tukey test at 5% of significance level. Soil and climate conditions of each region affect the physiological quality of buffelgrass seeds. Seeds located in bottom and middle portions of the panicle are more vigorous than seeds located in the top portion. The municipality of Po&ccedil;&otilde;es has better conditions for yielding buffelgrass seeds of better quality than the remaining municipalities.

ABSTRACT CARCASS QUALITY OF BROILERS FED RATION CONTAINING WASTE OF SAWI. Study was conducted to evaluate the effect of substituting part of ration with sawi waste meal on carcass quality and abdominal fat of broilers. Total of sixty unsexed day old chick broilers of MB-202 P strain were randomly divided into twenty units of pens, each of pen was filled with three heads of chicks.  Birds were maintained during forty days. Levels of substituting part of ration with sawi waste meal were  0, 5, 10, 15, and 20 percents. Each treatment had four replications using completely randomized design with 5 x 4. Fresh water and ration were given ad libitum. Birds from day old chick to the age of twenty one days old were fed with BR-21E ration for all treatments. The treatments of ration were fed at ages of twenty two days old to the end of study (period when all animals were slaughtered). Data were analyzed using F test and Tukey test for the significant F test. Results showed that control treatments were significantly different (P<0.05) with those others four treatments for carcass weight, but not significantly different with those others four treatments for carcass percentages and abdominal fat. Therefore, sawi waste meal can be used to substitute part of ration up to 20 percents for broilers ration in term of the carcass percentages and abdominal fat.   Key words: Sawi waste meal, broilers, carcass quality.
