This study was carried out in 2017 at the Federal University of Agriculture, Makurdi Nigeria. The study was aimed at evaluating the effect of packaging materials and storage period on the vigor parameters of some selected varieties of soybeans in Makurdi. The experimental design was 3x5x6 factorial CRD comprising 3 varieties, 5 storage periods and 6 packaging materials by 3 replicates. Samples were collected from National Cereal Research Institute, Yandev sub-station. The soybeans were cleaned, dried and the moisture content noted. Five hundred grams was measured into the various packaging material stored and at Strategic Grains Reserve, Federal Ministry of Agriculture Makurdi. The seeds in storage was sampled periodically (2, 4, 6 and 8 months) to determine quality by conducting standard germination test with 100 seeds (100 seeds/rep). The investigation revealed that V3 (TGx 1448-2E) stored for 2 months had the highest Shoot seedling length while V1 (TGx 923-3F) stored for 8 months had the least shoot seedling length. Soybeans stored in cloth had a very high Shoot seedling length at 2 months but dropped thereafter and turned out to be the lowest at the end of the storage period. V2 (TGx 1904-6F) stored in laminate paper produced the longest Shoot seedling length and also produced the shortest with V1. The seedling root length was longest in V3 stored for 2 months and least in V1 stored for 8months.Soybeans stored in cloth for 2 months produced very high SRL 2 months but dropped to 0.00 at the end of the storage period. V2 did better in LDPE than all the packaging materials. V1 had the shortest SRL in soybeans stored in bottle. The highest seedling vigor was recorded in V3 stored for 2 months while the lowest seedling vigor was recorded in V1 stored for 8 months. V2 in plastic container had the highest seedling vigor whileV1 in plastic had the lowest. However, significant differences were observed at (P< 0.05) in the interaction effect. In the present study, LDPE proved to be the best packaging material and the variety that had more resistance to deterioration was V2 (TGx 1904-6F). Soybeans that are stored at ambient should be in storage material that are impervious to air and moisture otherwise the seeds will lose viability and vigor. In addition, varieties that are prone to fast deterioration should not be stored longer.

Soybeans are the leguminous vegetable of the pea family that grows in a tropical, subtropical and temperate climate. Protein and oil are soybeans seed components of great economic value. This work was carried out at the Seed Science Laboratory in the Federal University of Agriculture Makurdi, Nigeria. It was aimed at assessing the protein content of soybeans stored under ambient condition. The experimental design was factorial in 3x5x6x factorial completely randomized design (CRD) comprising 3 varieties, 5 storage periods and 5 packaging materials by 3 replicates. The varieties investigated were TGx 932- 3F, TGx1904- 6F and TGx1448- 2E stored in cloth, glass bottle, plastic container, low-density polyethene and laminate paper. The storage periods were 0, 2, 4, 6 and 8months Least significant (LSD) at 5% was used to compare the treatment means. The seeds in storage were sampled periodically (2, 4, 6 and 8 months) to determine the protein content. The protein content of the samples was determined according to the standard method. TGx 1448- 2E (V3) had the highest protein content while TGx 1904- 6F (V2) had the least.  The highest protein content was recorded in soybeans packaged in a plastic container (43.55) while the least was recorded in soybeans that were not packaged in anything (control). The investigation showed that soybeans stored for 8 months had the highest protein content of 44.01 and the lowest was in 0 months (36.47). It was observed that the protein content increased with increase in storage period. Significant differences ((P<0.05) were observed in all the main effects.  The result of the interaction between variety and storage period showed V3 (TGX-1448-2E) had the highest protein content when stored for 8 months and the lowest was V2 (TGX-1904-6F) at 0month (30.8) and the next lowest one was V2 at 2months (36.79). The interaction effect of storage period and packaging material on protein showed that the highest protein content was recorded at 8month and the lowest was recorded at the 0 months (36.467). The interaction effect of variety and packaging material on protein content showed variation. The highest protein content recorded was in V3 (44.795) while the lowest was for V2 (39.847). The highest interaction was between V3 x LDPE (44.795) and the lowest was V2 X laminate paper. However, there were significant differences (P<0.05) in all the interaction effects. The present study revealed that the protein content of stored soybeans varied with storage period, packaging material and variety.

A study on the effect of different packaging materials and storage conditions was carried out on keeping quality of freshly prepared bleached lac packaged in five different types of packaging materials: Low Density Poly Ethylene (LDPE ), High Density Poly Ethylene (HDPE), Poly Propylene (PP), Metalized Polypropylene film (METPP) and five layer craft Paper Bag (PG). The samples were stored in both ambient and refrigerated conditions (14-160C) and quality parameters were evaluated at quarterly interval after 3, 6, 9 and 12 months of storage followed by comparison with samples stored in open condition. For storage under ambient condition in room, the flow value (fluidity), life (heat polymerization time) and acid value (AV) of the packaging material was highest for metalized film bag i.e.10mm, 5 min. and 70.69 respectively and impurity content was least (2%) after 3 months of storage due to high amount of moisture (4.12% db) retained in the sample. These parameters were lower in other packaging materials due to lower moisture content (1.38-2.40% db) with the lowest value (1.01% db) in open storage condition. For storage under the refrigerated condition, these parameters were higher compared to ambient storage for all packaging material. Flow value, life and acid value of samples in the metalized bag were highest; 35mm, 10 min. and 74.36 after 3 months of storage. However, these parameters were lower in others packaging materials due lower moisture content (1.50-2.61% db) with lowest value (1.23% db) in open storage condition. The flow and life of samples packaged in metalized film bag were highest i.e. 25mm and 5 minutes respectively after six months of storage as compared to when packaged in others. During the study it was observed that keeping quality of bleached lac samples was better in metalized film bag (82.5µ) compared to other packaging materials for both ambient and refrigerated storage condition.

The objective of this study was to evaluate dormancy and physiological quality of seeds of rice cultivars during storage in different environments. After harvesting, the seeds of three rice cultivars (Seleta, Curinga and Relâmpago) were dried in the sun, to reach moisture content at around 13%. Then, they were packed in paper and stored in four environments: 5 ± 2 ºC / 70 ± 5% RH, 12 ± 2 ºC / 70 ± 5% RH, 18 ± 2 ºC / 65 ± 5% RH and in uncontrolled condition of temperature and relative humidity (natural). Physiological quality was evaluated at the beginning and at 3, 6, 9 and 12 months of storage by germination test, electrical conductivity, accelerated aging and sand emergence. The experiment was conducted in split plots in a completely randomized design with three replications. Environmental factor was applied in the plots, cultivars in the subplots and storage period in subplots. Cultivar Seleta showed higher dormancy, which was surpassed during storage regardless of environment conservation. In general, seeds stored in natural environment showed lower physiological quality. Only the seeds of cultivar Seleta, regardless of the environment, maintained germination above the minimum required for commercialization until six months of storage.

ABSTRACT Studying the physiological and biochemical behavior of Myrcianthes pungens seeds stored in different packages for up to ten months was the objective of this work. Seeds were collected in Toledo, Pato Bragado, and Marechal Cândido Rondon and stored in a cold and dry chamber (11 ºC and 6,3% RH) for ten months. The germination test and the germination speed index (GSI), the seedling length (SL), the seedling dry matter mass (DMS), and the tetrazolium (ZT) test were performed and, for each evaluation, the water content was determined. Non-parametric analysis was used. During storage, the water content of the seeds in the plastic and glass containers varied little, but decreased in the paper packaging. The germination was maintained for ten months when the seeds were stored in plastic containers and for two months in the glass and paper ones. The variables GSI, SL, and DMS presented upwards and downwards variations during the storage period. The ZT revealed that, in the plastic packaging, the seeds remained viable for up to ten months, in glass, up to two months, and in paper, up to four months. Therefore, seeds of Myrcianthes pungens with high initial quality can be stored in a cold and dry chamber in plastic bags, maintaining viability and vigor for a period of ten months

In this paper, the effect of the packaging material and storage method on red raspberries produced at Reggio Calabria (Italy) was studied. For this purpose, the fruits were stored immediately after harvest in different conditions: in the fridge at 1 °C and in the freezer at −20 °C, using different packaging materials, two new patented films (nanoactive A) and (nanoactive B), one common packaging film (polyethylene terephthalate), and other fruits were left without any packaging material. Chemical parameters were analysed at harvest to have the initial characteristics without any conditioned storage and to distinguish the post-harvest effect on the fruits, then daily for storage in the fridge and monthly for storage in the freezer. The aims of our project were first to determine the qualitative characterization of these red raspberries, the optimization of their shelf-life during time in the fridge or freezer, using the different types of packaging materials and finally to highlight the usefulness of the new patented packaging materials. Nanoactive A film showed the best shelf-life in the fridge, and after 14 days the values, given as mg/100 g fresh weight, were: total phenolics (166.70), monomeric anthocyanin content (50.82), flavonoids (24.64), ascorbic acid (32.42), and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) assay (95.93).
