Abstract. Seed storage is one of the efforts to maintain seed quality until the seed is ready to be planted. Some factors that influence seed quality after the storage period are seed storage pest attack, packaging type and seed charac-teristics of each cultivar. The objectives of the experiment was to determine the combination of dosage of clove oil, packaging type and mung bean cultivar. This research consisted of two series of experiments: to study the effectiveness of a combination of clove oil dosage with cultivars and tested combinations of packaging types with two mung bean cultivars. The first experiment was conducted in January - April and the second in April - June 2017 respectively. The first experiment was to obtain the effect of a combination of clove oil dosages (0,0 ml kg-1, 0,5 ml kg-1, 1,0 ml kg-1, 1,5 ml kg-1 and 2,0 ml kg-1) with two mungbean cultivars (Vima-1 and Vima-2). Furthermore, the second experiment was to examine the types of packaging (jute bag, aluminum foil, paper bag, plastic bag and glass bottle) with cultivar type (Vima-1 and Vima-2) .The quality of the seeds was tested three and six months storage respectively. The first experi-mental results showed that clove oil treatment had no significant effect on the population of Callosobrochus sp after three months storage, percentage of broken seeds, weight of 100 grains and germination capacity. In general, Vima-3 cultivars that combined with dosages of clove oil  gave better quality than  of Vima-1 cultivars. The second experimental results showed that the paper bag packaging type and the jute bag are not able to maintain the seed viability and vigor more than  ≥ 80% of the standard quality. Aluminum foil, plastic seals, and glass bottles are able to maintained the seed quality of both cultivars after a six-month storage period.Keywords: clove oil, types of packaging, Mung bean cultivars, storage Sari.

AbstractSeed moisture content (SMC) is an important attribute to seed quality. Maintaining seed dryness throughout supply chain (The Dry Chain) prevents seed germination and quality losses. Ambient relative humidity (RH) and temperature affect seed moisture and thereof seed moisture isotherm. Present study was conducted to compare the moisture adsorption isotherms of wheat, maize, cotton and quinoa seeds packed in hermetic Super Bag and traditional packaging materials including paper, polypropylene (PP), jute and cloth bags. Seeds were incubated at 60, 70, 80 and 90% static RH. Nearly straight line moisture isotherms for all crop seeds were obtained in Super Bag. Seed moisture contents increased in traditional packaging materials with increasing RH. At higher level of RH, moisture contents increased slightly (1-2%) in Super Bag, whereas this increase was much higher in traditional packaging materials (≈9% higher than original SMC at 90% RH). In second study, seeds were dried to 8 and 14% initial seed moisture contents using zeolite drying beads and were stored in hermetic and traditional bags for a period of 18 months. For all crop seeds, germination was severely affected in all packaging materials both at 8 and 14% initial SMC except storage in Super Bag at 8% SMC. Wheat seed stored in Super Bag at 8% SMC almost maintained initial germination while germination of cotton, maize and quinoa seeds declined 7%, 14% and 30% respectively in Super Bag at 8% SMC. Seed storage in Super Bag can help to prevent the significant increase in seed moisture at higher RH as is evident from moisture isotherm study, thus helps to preserve quality of maize, wheat, cotton and quinoa seeds by maintaining The Dry Chain throughout the storage period.

Increased productivity of cocoa needs high quality of cocoa seeds which are generally provided by certified seed gardens located far from smallholders farm, where seed delivery takes long time and may reduce physiological quality of seeds. One effort to maintain the seed quality is by treatment the seeds with polyethylene glycol6000 (PEG 6000). This study was aimed to study the interaction of PEG 6000 concentration and storage period on cocoa seed quality, and to determine the best concentration of PEG 6000 and storage period to maintain cocoa seed quality. The research was conducted in seed storage room, seed laboratory and green houseof PPPPTK, Cianjur. The experimental design used was a factorial completely randomized design and each combination treatment repeated three times. The first factor was concentration of PEG 6000 of 0%, 20%, 40%, and 60%, and the second factor was the storage period of 3 weeks, 6 weeks, 9 weeks, and 12 weeks. The results showed that concentration of PEG 60% with three weeks storage period was able to minimize the number of moldy seeds. The concentration of PEG 20%, 40%, and 60% were able to prevent seed germination in storage until six weeks. Concentration of PEG 6000 20% was able to maintain moisture content, seed germination, and germination rate.Key words:cocoa seed, storage, recalcitrant, PEG

In Kenya, spider plant (Cleome gynandra L.) has gained popularity among consumers due to its nutritional and medicinal values. In the local markets, bundles of leafy shoots as well as uprooted young plants are offered at fairly high prices in many parts of Kenya. Existing evidence suggests that spider plant is endowed with higher level of nutrients than its exotic counterparts. The leaves contain over and above the normal recommended adult daily allowance of vitamins A and C, calcium and iron. However, quality of spider plant seed is affected by one or more factors that cause negative response during seed handling and storage. The purpose of this research was to increase insight into how the seed quality of spider plant is affected by different packaging containers, seed moisture content and storage temperatures, with a view to finding out the optimal method of packaging and storing of these seeds. This study was carried out using seeds dried above silica gel to four target moisture levels: 20%, 10%, 5% and 2% moisture content. Dried seeds were sealed in aluminum foil packets and polyethylene packets and stored at three storage temperatures: ambient (22oC to 30oC), 5oC and minus 20oC for three and six months. After each storage period, seed samples were drawn and viability and vigour tests carried out. Data sets were factorially combined and subjected to Analysis of Variance (ANOVA)and descriptive analysis. Means separation was by Least Significance Difference (LSD).Levels of significance, means and standard deviations were obtained for various data sets. Seed stored for six months at 5% moisture content and minus 20oC recorded the highest seed quality. There were no significant differences between seeds packaged in aluminum foil packets and polyethylene packets. In this study, a germination of 85% was recorded for seed dried to 5% moisture content and stored at room temperature. Therefore, on the basis of these findings, farmers can dry their seeds at about 5% moisture content, package them in polyethylene (since readily available) and store at room temperatures for six months.

Physiological Quality

The preservation of seed quality during the storage period depends not only on the conditions during production and harvesting but also on the storage and maintenance of appropriate storage product conditions. Thus, the aim of this study was to evaluate the physiological and sanitary qualities of maize landrace seeds stored under two conditions. The maize seed batch varieties Oito carreiras, Cabo roxo and Lombo baio were used. Tests included germination, first count, cold test, accelerated aging and sanity. Based on the results it was concluded that the physiological quality of these seed varieties decreased with the storage period. The major fungi identified in the maize seeds during storage were from the genera Aspergillus, Fusarium and Penicillium, which caused deterioration and reduction of the physiological quality. Storage using a paper bag at a temperature of 10 °C did not prevent the deterioration of maize seeds but was more effective at preserving the quality of the seed compared with a plastic bag at room temperature.

Seed quality is a key factor to succeed in a yield generation and storage is an important activity to control the physiological seed quality, as it preserves seed viability while maintaining its robustness at a reasonable level between planting and harvest. On this basis, the goal of this study was to evaluate the physiological quality of snap bean seeds stored in different types of packages and storage conditions. Eight genotypes comprising six lines and two controls were analyzed. It was applied a completely randomized block design with four replicates in a factorial scheme (8×2×2×7).Seed storage was performed in permeable and impermeable packages under controlled and uncontrolled conditions. The physiological seed quality was evaluated by means of germination and vigor tests. The different types of package and storage conditions influenced the physiological seed quality. Under controlled storage conditions, the permeable and impermeable packages were more efficient in controlling the physiological quality of snap bean seeds.

Seed quality may be affected by several factors, including permeability, color, and lignin content in the seed coat. This study aimed at evaluating influence of lignin content in the tegument of seed samples of six different soybean cultivars, in which half of each sample was inoculated with the fungus Aspergillus flavus, on the physical and physiological quality, and on the seed health, during 180 days storage period, under cold chamber with controlled conditions of temperature and RH. For that, at each interval of 60 days, samples were removed, and the physiological quality of these seeds was assessed by means of moisture and lignin contents; and by tests of seed health, germination, and electrical conductivity. The moisture content of seeds remained constant during all storage period. In the seed health test, it was found that inoculation was efficient, once the minimum incidence of the fungus in the inoculated seeds was 85%. In the germination test, there was a trend of reduction on percentage germination with the increase in storage period. However, there was an increase on electrical conductivity of seeds assessed. It was concluded that there is no interference of the lignin content in the seed coat on the resistance to infection by the fungus Aspergillus flavus, even after seed storage for a period of 180 days.

Relevance. Biological features (morphometric indicators, viability and germinating power) of Poterium polygamum seeds found in natural communites of the Stavropol Territory have been studied. The conservation of wild-growing plant species in the natural population and the rational use of their potential are relevant.Methods. Years of study — 2013–2021. The subject of the study is Poterium polygamum seeds. Seeds were collected in 2013. Studies were carried out according to the methods of studying seed material. Freshly harvested seeds and seeds of different shelf life were germinated in petri dishes at a temperature of 18–20 °C.Results. The collected seeds of Poterium polygamum are quite large. The length of the seeds is 4–5 mm, the width is about 2.5 mm. The mass of 1000 pieces of seeds on average was 10.59 grams. Complete absence of viability of freshly harvested Poterium polygamum seeds was revealed. After three months, seed viability was 97%. This is a shallow physiological rest associated with the post-harvest maturation period. During the storage of seeds, their high germination was established — from 70 to 100%. The duration of seed storage is 8 years. The largest number of germinated seeds and their germinating power were noted in the third year of their storage (100%). Seeds germinated on the third or fourth day. The differences between the viability of seeds and their germinating power are not great. In the eighth year of storage of Poterium polygamum seeds, viability and germinating power were slightly reduced. The storage period of seeds, in which they retain the ability to germinate and the germinating power, is long. It has been found that the wild species Poterium polygamum belongs to plants with a high (70 to 100%) viability. This species is regularly resumed in the natural population. The revealed biological features of Poterium polygamum seeds can become the scientific basis during the reconstruction of degraded natural grass stand and in selection work.

<p>ABSTRACT<br />Information of seed quality during storage can be determined through the actual storage and storability vigor estimation. This study aimed at comparing effective accelerated aging method<br />between physical and chemical, and studying the seed deterioration during storage in ambient (T =28-30 0C, RH=75-78%) and AC (T =18-20 0C, RH =51-60%) condition with three levels of initial moisture content (8-10%, 10-12%, and 12-14%) for 20 weeks. The final objective of this research<br />was to develop model for storability vigor of papaya seed. Two experiments, accelerated aging and seed storage were conducted at Seed Laboratory, Department of Agronomy and Horticulture, Bogor Agricultural University from October 2015 to May 2016. A completely randomized design with nested factors and four replications was applied to both experiments. The results showed that physical accelerated aging using IPB 77-1 MMM machine was more effective than chemical accelerated aging using IPB 77-1 MM machine for papaya seed. The viability of seed stored in AC condition remained high until the end of the storage period, whereas it declined at 16 week storage period in the ambient condition. The viability of seed with initial moisture content of 12-14% declined faster than that of initial moisture content of 8-10% after 18 week storage periode. The model used to estimate the storability vigor of papaya seed accurately was the equation y = a + b expcx where y : storability vigor estimation, x : aging time and a,b,c : constant value. Simulation of storability vigor estimation with constant value of a, b, c and input of aging time can estimate storability seed vigor in actual storage.<br />Keywords: accelerated aging, IPB 77-1 MM machine, IPB 77-1 MMM machine, seed storage, simulation</p><p>ABSTRAK<br />Informasi mutu benih selama penyimpanan dapat diketahui melalui penyimpanan secara aktual dan pendugaan vigor daya simpan.

Seeds of native forest species for food and seedling production have a growing demand that impacts the need for studies involving seed storage in order to maintain good levels of germination quality. Thus, scientific analyzes that explore the physiological potential of the seeds of these species are necessary, especially for the pink pepper (Schinus terebinthifolia Raddi.), a species used as an alternative source of income for traditional communities and which has been arousing interest due to the consumption of its fruits as a condiment in the national and international market. This work aimed to assess the physiological quality of pink pepper seeds according to the storage period and seed size. The seeds came from a rural settlement, a pioneer in the extraction of pink pepper, in the state of Rio de Janeiro, Brazil. The seeds were evaluated for moisture content, germination, first count, length and dry weight of the germinated seedlings, during the period of time that they remained stored and the size of the seeds. The results allowed to conclude that: i) the germinative percentage of the stored pink pepper seeds decreased over the months; ii) the moisture content of the seeds decreased over the months evaluated iii) the different sizes of seeds did not show differences in germination and storage time and iv) values of length and dry weight of the seedlings did not differ according to the period of storage.

An experiment was carried out at Germplasm Centre and Plant Biotechnology Lab, Department of Horticulture, PSTU to evaluate the growth, seed yield and quality of hybrid F1 chilli (cv. Sonic) crossing male line (LTSL-004-M) and female line (LTSL-004-F) along the viability of productive seeds influenced by NPK fertilizers during the period from November 2015 to October 2016. Ten different treatments of NPK fertilizers were used. Result showed that all the characteristics except primary branches and1000 seed weight were influenced significantly due to the application of NPK fertilizers. The tallest plant (69.88 cm), more leaves plant–1 (2491.33), highest number of secondary branches plant-1, tertiary branches plant-1 (5.00 and 88.00, respectively), number of flowers and hybrid fruits plant–1 (1533.00 and 12.33, respectively) and weight of seeds (4.03 g plant–1) along with required more time (54.67 days) for flowering were obtained from the application of 145 kg N ha–1, 175 kg P ha–1 and 96 kg K ha–1 (T4) which produced the highest final seed yield of chilli (4.03 kg ha–1). Application of T5 and T9 showed the highest number of primary branches (2.33). In seed viability characteristics T9 treated seeds showed the highest germination (100, 97.33 and 94.97%) at 1st, (1 MAH - Month After Harvest), 2nd (2 MAH) and 3rd (4 MAH) observations, respectively. The T3 treated seeds performed well in respect of Seed Vigour Index (SVI) at 1st and 2nd observations (8.00 and 7.48, respectively) but T9 treated seeds showed the highest SVI (6.32) at 3rd observation. Above indicating all characteristics were lowest under only recommended doses of NPK T1 as control treatment except days to first flowering. The observations suggested that production of hybrid chilli seeds could be enhanced by applying T4. While seeds of chilli treated by T9 in field level showed long time viable. Application of 145 kg N ha–1, 175 kg P ha–1 and 96 kg K ha–1 may be suggested for seed production of chilli and 110 kg N ha–1, + 175 kg P ha–1 + 115 kg K ha–1 for keeping the long time seed viability.
