The speed of the deterioration of oil-seeds depends on conditions of the storage environment and understanding dormancy release time is important to increase the amount and uniformity in germination. Therefore, the present study was conducted to evaluate the effect of different packaging materials and storage environments on viability and dormancy of sesame. The black sesame seed was stored in three packaging materials (woven polypropylene bag, IRRI super bag, metal bin) under two environment conditions (ambient and cold storage) for eight-month (initial storage, 2-month, 4-month, 6-month and 8-month). The effect of storage environments, packaging materials and storage durations on germination percentage, germination index, seedling vigor index I and II were significant. The moisture content decreased in the early parts of storage periods and then increased in later. The moisture content of seeds in the packaging materials increased in long storage due to the effect of seed respiration and heat accumulation in a package. Higher viability was observed in ambient storage, and in a woven polypropylene bag. Because the dormancy release was slow in low- temperature condition and the carbon dioxide concentration in the airtight package inhibited the dormancy break. It also increased during storage and the earliest fully dormancy break has occurred in six-month of woven polypropylene bag storage under ambient condition. Therefore, the germination and dormancy release of sesame were influenced by storage environments packaging materials and storage durations.

Laboratory experiments were carried out to determine the effects of harvesting stages on the seed quality of chickpea. Chickpea seed of three varieties (BARI Chola-5, BARI Chola-6 and BARI Chola-8) were collected at three harvestings times i.e. from three different times at 7 days interval prior to harvesting, viz. i) when the pods were yellowish with a few yellow greens (H1 stage), ii) when most of the pods were light brown with a few yellow (H2 stage), and iii) when all the pods were completely brown and dry (H3 stage). Significant variation was observed in three varieties of chickpea for all the parameters studied except vigour-I. The highest germination percentage, root length, shoot length, root plus shoot length and vigour-II was observed in BARI Chola-5 which was significantly higher over BARI Chola-8. Dry weight was found to be significantly higher in BARI Chola-8 which was identical to BARI Chola-6. Moisture content was significantly higher in BARI Chola-8. Seed collected at the stage when most of the pods were light brown with a few yellow (H2 stage) recorded the highest germination percentage, dry weight, vigour-I and root length. Pods (H1 stage) gave the highest moisture content in seeds. BARI Chola-5 seeds recorded the highest germination at H2 stage. Interaction effects of varieties and harvesting stage had non-significant effect on germination percentage, vigour-I, shoot length and vigour-II in both the years.

The study was aimed at determining the effect of sulphur and Bradyrhizobium fertilized seed at different initial moisture content of seed and storage container, to improving the germination percentage of groundnut seed. The germination test was carried out after storing the seed for five months. Results revealed that seeds obtained from 60kg S/ha. stored in polythene bags retained the germination percentage up to the standard level of ISTA for 5 months efficiently. Least initial moisture content of seed (7.25 %) produced from the above doses of fertilizer elements also played a vital role in keeping the quality of stored seed. Results in the respect of storage performance in terms of percentage of germination indicated that groundnut seed obtained from sulphur and Bradyrhizobium fertilizer elements during production and stored in polythene bag can retain better seed quality, provided seed were dried to a safe moisture level of 7.25 % to 8.46 %.

The use of methods and technologies such as drying and film coating can bring significant contributions to the farmer. This experiment was conducted in order to evaluate the effect of drying and film coating on the physiological quality of eggplant seeds during storage. Hybrid seeds UGA MS1 produced by the company Hortiagro - Ijaci, MG were used. Seeds were subjected to two types of drying: slow (room temperature) and quick (oven with forced air circulation at 35 ºC). The chemical treatment was performed with the Captan product at a dose of 250 grams per 100 kilograms of seed and for the recoating were used three doses of polymer: (0, 3 and 6 mL.kg-1 of seeds). The physiological quality of seeds was evaluated every three months until reaching the period of nine months using germination test, seedling emergence test and seedling establishment. There is a reduction of physiological seed quality during the storage. The slow drying of eggplant seeds results in better quality seeds. The use of polymer reduces the germination percentage, germination speed index and the percentage of seedling emergence.

The experiment was conducted to investigate the seed quality of Indian spinach for three months stored at different containers (Plastic pot, polythene bag and cloth bag) during 2013-2014 at Seed Technology Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur. The initial moisture content of the seed was 9.89% with 75.00% germination. However, after two months, the seed had a different range of increased moisture content with reduced germination percentage depending upon the packing materials. Among the three containers, seeds stored at cloth bag absorbed more moisture (14.36%) from surrounding atmosphere followed by the moisture content, 12.67% and 11.50% of polythene bag and airtight plastic pot, respectively. Seeds stored at plastic pot, polythene bag and cloth bag exhibited 65.00, 64.00 and 50.00 per cent germination, respectively. Similarly, the fresh weight and dry weight of seedling and seedling vigor were also decreased. The seeds of plastic pot were good in term of germination capacity, fresh and dry weight and vigor index in comparison to those stored at cloth bag and polythene bag.Int. J. Agril. Res.

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 experiment was conducted in the Laboratory, Department of Plant Pathology,  HSTU, Dinajpur during April – July 2010 to know the effect of abiotic and biotic  factors, storage periods and storage containers on the seed quality of French  bean. Tin container showed the highest germination, normal seedlings and  vigour index which were followed by polythene bag, where Gunny bag showed  the lowest germination, normal seedlings and vigour index upto 60 days after  storage. The highest 1000-seed weight, moisture content, abnormal seedlings,  seed rot and incidence of the Fusarium oxysporum were recorded in Gunny bag,  where the lowest of these parameters were recorded in Tin container. Seed  colour of Tin container were more or less same as initial colour, but seeds of  Gunny bag were changed into fade or brown colour at 60 days after storage.  Moisture content, 1000-seed weight, abnormal seedlings, seed rot, fungi  association were increased, but germination and normal seedlings were  decreased with the increase of storage periods. Among the three containers, Tin  container was the best and the Gunny bag was the worst storage containers upto  60 days of storage for French bean seed.

Improved upland rice cultivars introduced in Volta Region, Ghana, have been perceived to store poorly compared to farmers' traditional cultivars. A survey was conducted in 2003 in the Hohoe district of this region, where a Participatory Varietal Selection programme had started in 1997, to gain insight into farmers' seed production and storage practices that are likely to affect seed quality in storage. Farmers rated keeping quality (p < 0.001), tolerance to storage pests (p < 0.001), seed quality (p < 0.001) and establishment of their local cultivars Kawomo, Viono and Wuwulili as much better than the improved cultivar IDSA 85. Initial seed moisture content ranged from 12.8 to 18% and germination from 0 to 82%. There was a significant relationship between seed moisture content and duration of drying prior to storage (p < 0.001) and storage method (p = 0.015). Germination loss in storage was rapid at high moisture content and slow at low moisture content. Between 60 and 80% of seeds germinated after six months storage at 12.8% moisture content. The viability equation predicted accurately germination of farmer-saved seed stored under ambient temperature in Ghana. Except for the japonica rice cultivar WAB 126-18-HB, the traditional cultivars Kawomo, Viono and Wuwulili survived better in storage than improved cultivars. There is a need to improve seed quality of improved cultivars if farmers are to benefit from their higher yields and grain quality and to improve storage practices.

AbstractSeeds of the Brussels sprouts cultivar Asmer Aries and the cauliflower cultivar Hipop were subjected to ageing at 20% moisture content and 45°C for 24 or 30 h, respectively; all seeds retained high germination after ageing. Aerated hydration of unaged and aged seeds of both cultivars for 4–8 h at a range of temperatures (10–30°C), followed by drying, resulted in improved performance, except that germination percentage and rate of cauliflower were lower at 10°C. Thus, all treated seeds showed greater germination rate and seedling root length than the control, which may have resulted from the advancement of the process of germination. The deleterious effect of aerated hydration at 10°C on cauliflower could be explained by damage due to rapid imbibition; seeds that had imbibed slowly to close to full imbibition (41% moisture content) before aerated hydration showed no decrease in germination. The improvement of aged seeds after aerated hydration was also revealed by higher germination after the controlled-deterioration test, which indicated less deterioration in treated seeds. Furthermore, the optimum improvements for all seeds were observed at 25°C and were greater when the water was aerated than non-aerated. These observations indicate the activation of metabolic repair processes during aerated hydration, leading to a reversal of the deterioration sustained during ageing.

The technology developed by breeding programs is applied to coffee seeds; however, after processing and drying, they lose viability within a short period of time, thus making storage unsuitable. The objective of this research was to evaluate the quality of coffee seeds submitted to different drying methods and moisture contents during storage. The coffee seeds were submitted to conventional drying (slow shade drying) and fast drying in a static drier until they reached a moisture content of 40, 20, 12 and 5%. After this process, the seeds were stored in a cold chamber for 12 months, and seed quality was evaluated before and during storage by the germination test, electrophoretic patterns of heat resistant proteins, and the activity of isoenzyme systems. Conventional drying (slow shade drying) at 20% of moisture content maintains coffee seed quality until 12 months of storage.
