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.

This study aimed to assess the effect of different drying forms, environments, and storage periods on germination and sanitary quality of quinoa seeds cv. BRS Syetetuba. Seeds were submitted to drying in forced air circulation chamber at 30, 40, and 50 °C and in a suspended tray, in full sun, until they reached ±12% of moisture content. The observed drying data were adjusted to 10 mathematical models. The storage for 360 days was continuous in three different environments. Seeds were evaluated at 0, 6, and 12 months for germination, first count of germination, moisture content, and sanity tests. The experimental design was completely randomized, in a split split-plot scheme with four replicates. Among the studied models, Midilli was efficient in describing the drying curves of quinoa seeds. The storage environment influenced the loss of seed quality more than the drying temperature. The increased storage period caused a decrease on fungal seed incidence.

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.

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 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.

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.

<p>Watermelon seed being an oily seed is prone to rapid deterioration of its quality, hence maintaining quality during storage is germane. The study therefore investigated the effect of crude plant powder, storage containers and storage duration on the seed quality of two varieties of watermelon seeds. Seed lots each of 100 g of each variety were treated with 10 g of four crude plant powders of clove basil leaf, red chilli pepper fruit, garlic, neem leaf and a synthetic fungicide. All samples were stored in three storage containers (envelope, tin and glass bottle). Treated seeds were stored under ambient conditions for 180 days. Germination and seedling vigour were determined at 180 day time course after storage. Data were subjected to mean separation using Duncan’s Multiple Range Test. Significant differences were observed in the quality traits examined in water melon due to differences in variety, seed treatment, storage container and storage period. ‘Kaolak’ was the best in storage in terms of seedling vigour and viability. Glass bottle was identified as the best storage container in maintaining seed quality of water melon throughout the storage period. The use of organic materials especially neem and clove basil leaf powder proved much better for maintaining germinability and seedling vigour and extension of seed longevity than inorganic material.</p>

The experiment was conducted at the Seed Laboratory, Regional Agricultural Research Station, Bangladesh Agricultural Research Institute, Jamalpur in 2013 to study the effect of seed moisture content and storage containers on seed quality of soybean genotypes. Three genotypes of soybean (AGS 191, ASET 93 and Shohag), four initial seed moisture content (6, 8, 10 and 12%) and two types of storage containers (polythene bag and glass jar) were included in the experimental treatment. Seeds of soybean genotypes was stored at ambient condition were temperature ranged from 15.97 to 29.37 0C, relative humidity ranged from 75.21 to 86.23% and rainfall ranged from 0.00 to 425mm during the whole storage period. Seed moisture content (%), germination (%) and vigour index were recorded at 50, 100, 150 and 200 days after storage (DAS). Result showed that final seed moisture content increased with the increase of initial seed moisture content. Genotype AGS 191 showed the highest germination (%) and vigour index. Seeds stored in polythene bag or glass jar showed similar performance for germination (%) and vigour index. Highest seed moisture content significantly reduced the germination and vigour index errespective of containers. The results indicate that soybean seed can be stored safely for at least 200 days maintaining >80% germination and high vigour when stored in polythene bag or glass jar with 6-8% initial moisture content at ambient room temperature and relative humidity.

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
