This study aimed to evaluate the quality of Hevea brasiliensis seedlings, a GT1 clone, produced in protected environments in a variety of substrates. The treatments consisted of 13 substrates composed of combinations of cattle manure, soil from a ravine, medium vermiculite, superfine vermiculite and washed fine sand and two environments: a greenhouse with 50% shade using aluminized screen and a plant nursery with 50% shade using a Sombrite® screen. There were no replications of the environments; therefore, each one was considered an experiment. For each environment, a completely randomized experimental design with five replications was used to evaluate the substrates. Subsequently, the average squares of the residuals of individual variance analyses of these treatments (substrates) were evaluated, and because they did not exceed an approximate ratio of 7:1, a combined analysis of experiments was performed with Sisvar software. Two hundred eighty days after sowing, the dry weight, plant height, stem diameter, diameter at five centimeters above soil and the seedling quality indices were evaluated. Results indicated that substrates with a low amount of manure and sand and a high amount of vermiculite (S9 and S13) produced rubber tree seedlings of high-quality. The environment with greater radiation availability was better for the development of high-quality rubber tree seedlings.

The objective was to evaluate the production and post-harvest quality of fruit from grafted and non-grafted tomatoes. The experiment was carried out in a randomized block design with five treatments (Jiloeiro, Berinjeleira, Jurubeba, 'Intacto' rootstock and the witness the cherry tomato without grafting) and 16 replicates. In the evaluation of physical-chemical quality, the experiment followed a randomized block design in a 5x2 factorial scheme (rootstocks and storage temperatures, 10 ºC and room temperature) four replications. For a better productive contribution of the cherry tomato, the use of rootstocks from Jurubeba and Intacto is indicated, however, the use of a rootstock did not contribute to the durability and physicochemical characteristics of the fruit. When conditioned at 10 ºC, the fruits showed a better visual and physical-chemical aspect in relation to the ambient temperature, with increased durability of the product in all treatments.

The objectives of this research were both to know as well as to determine the exact concentration of lemongrass water extract applied during storage on the quality of tofu. A complete randomized experimental design with two factor of treatments was utilized. The first factor was concentration of lemongrass water extract with 3 levels of treatmens, i.e : T1 : 1 kg of lemongrass : 2 L of water, T2 : 1 kg of lemongrass : 3 L of water, T3 : 1 kg of lemongrass : 4 L of water. Whereas the second factor was the storage time, i.e : L0 : 0 day, L1 : 2 day and L3 : 4 day. Variables observed including chemical, and microbial. They consit of protein, moisture, TPC, and Salmonella. Results showed that lemongrass water extract with the concentration of 1 : 4 stored for 4 day had high protein and moisture, content which were 15.4%, and 74.37%, respectively results from microbial test showed that microbial growth was suspressed by the treatments and the content were still in the range set by Indonesian National Standard Agency.

Jenang, or what is often called dodol, slab, or gelamai, includes dense, chewy, half-processed products. Jenang, which was innovated from chayote, has a relatively short shelf life, which is only able to survive 3-5 days at room temperature (27ºC). Therefore, a good packaging is needed that can extend the shelf life of one of them is edible coating, which is the packaging of edible materials. Edible coating is one of the efforts that can be done to maintain the quality of a food. The purpose of this study was to determine the quality and estimation of chayote with and without edible jenang based on physical, chemical, and microbiological parameters. In this study using the analysis of water content, peroxide numbers, and total microbes and using the edible dip method. From the research it can be seen that the chayote jenang based on physical quality in edible samples can maintain the water content so that the texture remains elastic compared to without edible until the 15th day. Based on the chemical quality in jenang squash with edible, oxidation only occurred after storage on the 22nd day. Microbiological quality in the conjoined pumpkin jenang coated with edible or without edible was overgrown with a total amount of yeast mold ≥300,000 Cfu / g.

Despite the importance of the Amazonian species Schizolobium amazonicum, there is still no official protocol to favor the germination process of its seeds. The objective of this study was to evaluate methods of overcoming dormancy of paricá seeds and the quality of seedlings produced. The work was carried out at the Federal Institute of Education, Science and Technology of Tocantins-Campus Araguatins. The experimental design was a completely randomized design with seven treatments and four replications. The treatments consisted of: intact seeds; lateral mechanical scarification of the tegument with electric emery for 2 seconds; lateral mechanical scarification of the tegument, using sandpaper number 50 for 1 minute + immersion in water at room temperature for 12 hours; chemical scarification of the tegument with caustic soda at 20% concentration for 30 minutes; chemical scarification of the tegument with caustic soda at a concentration of 20% for 45 minutes; immersion in water at 80 ºC + stay in water (room temperature) for 12 hours; immersion in water at 90 ºC + stay in water (room temperature) for 12 hours. The treatment with lateral mechanical scarification of the integument using electric emery for 2 seconds is the most suitable for overcoming dormancy in paricá seeds. Methods of overcoming dormancy had no influence on the quality of paricá seedlings.

Abstract: Seeds storing under appropriate conditions reduces the speed of the seeds deterioration process. The aim of this study was to evaluate pre-packing cooling and types of packages in the maintenance of the physiological quality of soybean seeds during storage. The completely randomized experimental design was used, with four replications, considering a factorial arrangement involving or not the pre-packing cooling of the seed mass, three types of packages (multi-layer paper bag, big bag, and polyethylene container), and five storing periods (0, 2, 4, 6 and 8 months). The physiological quality was evaluated by the tests of first germination count, germination, accelerated aging, electrical conductivity, emergence speed index and emergence. The use of packages with larger amount of seeds (big bag and polyethylene container) did not favor the maintenance of the pre-packing cooling temperature. The types of packages did not show significant differences in the seeds viability during storage, up to eight months, regardless the pre-packing cooling. The cultivars seeds showed different tolerance to storing, i.e. seeds of the cultivar TMG 1176 had lower storing potential comparing to the seeds from the cultivar SYN 9074.
