Abstract Successful crop production depends initially on the availability of high-quality seed. Seed viability and vigour of four kenaf varieties during storage were investigated. Seeds of each variety were packed inside thick polythene bags and kept in Seed Stores under ambient conditions in two storage locations (Federal University of Agriculture, Abeokuta (FUNAAB) (29.8°C, 59.10 RH%) and Institute of Agricultural Research and Training, Ibadan (27.5°C, 64.68 RH%) for 240 days (8 months). Seeds were sampled during storage at 0, 60, 120, 180 and 240 days and tested for seed viability and seedling vigour index. Data collected on seed viability and seedling vigour were analyzed using ANOVA, mean separation using Duncan Multiple Range Test at 5% probability level and PROBIT analysis. The results showed differential responses in the two quality traits due to differences in storage location and varieties. Ibadan storage location provided more favourable conditions for higher seed quality compared to Abeokuta location while Ifeken 400 and Tianung had the best storage potential. The study showed that under ambient humid tropical conditions, storage period should not exceed 180 days (6 months) in order to maintain higher physiological quality with little or no cost. The PROBIT result revealed that the highest seed shelf life (longevity) of kenaf seeds of 8 to 9 months was derived for seeds of Ifeken 400 and Tianung stored in Ibadan and Abeokuta. The shortest shelf life of 6 months was estimated for Ifeken 100 stored in both locations.

Vigour Index

One of the most important basic needs for higher agricultural production is quality seed, characterized by high viability and vigour. Maintenance of seed viability and vigour from Harvest till the next growing season is of the utmost importance in a seed production programme. During seed storage, qualitative and quantitative losses of up to 20% have been reported in India. The poor seed quality may also be due to the poor storability which is very often being decided by the internal and external factors. In pulses, the major cause for seed deterioration during storage is bruchid damage. In this context, evolving an improved storage strategy to prolong the shelf life of seeds under ambient storage conditions with easily available cost-effective resources was carried out. The experiment was conducted at the Department of Genetics and Plant Breeding, Faculty of Agriculture, Annamalai University, Annamalai nagar. Freshly harvested seeds of black gram cv. ADT 3 were cleaned and graded using BSS, 8x8 wire mesh sieve. Then seeds were dried under sunlight to bring the moisture content to required level (8.5%). The seeds were treated with Thiram @ 2g kg-1, Neem oil @ 10ml kg-1 and Malathion dust @ 200 mg kg-1. Two hundred and fifty grams of seeds from all treatments along with control were packed in two containers viz. cloth bag and polythene bag (700 gauges) with three replication and stored in at ambient temperature (30o c – 35o c) and relative humidity of 52-80%. Seed samples were drawn from each replication at monthly interval for assessing the viability and vigour. Germination test was conducted in between paper method and seedlings were evaluated on seventh day for vigour index bruchid infestation. The untreated seeds recorded lower germination per cent and vigour index after seven months of storage. There was no bruchid damage on seeds treated with neem oil @ 10ml kg-1 and thiram @ 2g kg-1. It was concluded that the shelf life of black gram seeds could be increased by

Reduction in germination of crop seeds due to depletion of food reserves and decline in synthetic activity due to ageing has become a serious concern to groundnut growers who need adequate, high quality seeds to sustain groundnut production. Therefore, to stimulate farmers’ interest in groundnut production, an experiment was conducted to evaluate some groundnut varieties for their tolerance to seed ageing stress, with a view to recommending varieties that can be considered for production in tropical countries. Seeds of nine elite groundnut genotypes, sourced from The International Crops Research Institute of Semi-Arid Tropics (ICRISAT), Kano and three other genotypes sourced from local seed dealer in Ibadan, Nigeria were subjected to seed quality assessments in the seed testing laboratory of Institute of Agricultural Research and Training, Ibadan. The seed lots were subjected to accelerated ageing procedures of 42 °C temperature and 100% relative humidity for 24 hours. Twenty-five seeds of each genotype were drawn from each genotype in three replicates at 3, 6, 12 and 24 hours of ageing. The drawn samples were reassessed to determine their tolerance ability to ageing stress. Percentage germination was transformed using arc-sine before the data on preliminary seed germination and seedling vigour data and seed ageing data were subjected to analysis of variance (ANOVA) using SAS™ Means were separated using Duncan Multiple Range Test (DMRT) at 5% level of significance while k-means non-hierarchical clustering analysis was used to group the genotypes based on their response to the ageing. Result showed that seeds of the groundnut genotypes differ in their response to ageing stress factors. Seeds of ‘Samnut-24’, ‘Samnut-25’ and ‘Ex-Dakar’ (R) were found to be more tolerant to ageing stress while ‘Samnut 22’ and ‘Boro White’ were susceptible to ageing stress. Optimum ageing for 24 hours is recommended for testing seeds of groundnut varieties for storage tolerance

Aims: In an attempt to improve the yields of Citrullus lanatus’s wlêwlê oilseed cultivar, generally low due to the lack of good germination seeds, the effect of fruit age at harvest and fermentation methods were studied. The present study is a contribution to the improvement the African oleaginous Cucurbits seed production system by optimizing the date of harvest combined to seed fermentation methods through enhancement of seed germination and seedling vigor. Study Design: Seedling vigor was evaluated on farm trial using five completely randomized blocks represented by seedbeds constituting each, one replication. Place and Duration of Study: The trials were carried out from July to December 2020, at the experimental farm of the Nangui Abrogoua University in the district of Abidjan, southern of Côte d'Ivoire between 5°17' and 5°31' North latitude and between 3°45' and 4°31' West longitude. Methodology: Fruits from grown plants were harvested at five different times  20, 25, 30, 35 and 40 days after anthesis (DAA)] and seeds fermented following four methods  fermentation at ambient air (SFA); fermentation in a plastic bag exposed at ambient air (SFB); fermentation in plastic bag buried in 30 cm depth (SFD) and control or non-fermented (NF)]. Seeds from these 20 treatments (5 harvest time × 4 fermentation methods) were sown for viability tests in laboratory and seedling vigor in the field. Results: Analysis of variance (ANOVA) showed that delaying harvest time (from 20 to 40 DAA) significantly (P < .001) improved fruit weight (from 512.20 to 760.50 g) and its seed content (from 71.75 to 230.70 seeds/fruit), seed size (length: 10.69 to 11.42 mm and width: 5.31 to 5.90 mm) and weight (5.16 to 6.37 g) as well as their viability (from 67.75 to 89.50 %). Moreover, in spite of facilitating seed extraction, all three fermentation methods (SFA, SFB and SFD) significantly improved seed viability and seedling vigor compared to control (NF) seeds. The highest agronomic performance (seed viability and produced seedling vigor), was obtained with fermentation under closed and deep confinement (SFD), followed by the closed confinement (SFB) and then by the open environment (SFA). Positive interaction (harvest time × fermentation method) revealed that the best performance was achieved with later harvested seeds (40 DAA) and closed fermented seeds (SFD) which could provide a better seed quality. Conclusion: Agronomic performances (viability and vigor) are influenced by both harvest date and fermentation method. Late harvesting of the fruit (40 DAA) and fermentation in a very confined deep soil condition (SFD) ensures the production of high germination quality seeds.

An investigation was undertaken with main objectives to know the effect of desiccants on seed quality parameters of crop seeds during storage and to assess the benefit cost ratio of storage method (economics) in wheat with initial seed moisture content of 12.3 %, was carried out at Department of Seed Science and Technology, College of Agriculture, UAS, Dharwad. Quantity of desiccants stored per kilogram of seed in wheat seeds is 0.37 kg for zeolite beads, one kg for silica gel, calcium carbonate and control without desiccant in airtight container. The experiment was laid out in Completely Randomized Design with four treatments and five replications. Seed stored with zeolite beads recorded the highest germination (88.8 %) which was on par with silica gel (87.2 %) at the end of storage period. Lower seed moisture and hundred seed weight was observed in the seeds stored with silica gel at the end of storage period. Higher shoot length, root length, seedling vigour-I and seedling dry weight was observed in seeds stored with zeolite beads which was on par with Silica gel at the end of storage period. compared to control. Therefore, it can be concluded that the zeolite beads can safely be used for seed drying without impairment in seed quality.

<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>

Bird Damage

Thirty sorghum lines were evaluated under humid tropical conditions in Mayagüez, Puerto Rico in 1980. In order of importance, bird damage, seed molds, and rust were the major constraints to optimum yields and seed quality. Finches (Fringillidae) mostly Tiaris bicolor and black birds (Icteridae) mostly Quiscalus niger were the most common sorghum eating birds. Seed losses from birds varied from 0 to 97.3% depending on the sorghum line. The mean loss from birds over all lines was 50.7%. Only two sorghum lines, IS 7013 der (0%) and SC0414-12 (ADN 252) (3%) suffered less than 10% seed losses. Over all sorghum lines a strong positive correlation (r = 0.81**) was found between severity of bird damage and the length of the period between 50% flowering and 50% physiological maturity. A low correlation (r = 0.39*) was found between the 125-seed weight and the severity of bird attack. Twentyfive genera of fungi were found on sorghum seeds. Clean seed frequency (seeds without signs of fungi) was highly correlated with seed germination in in vitro tests (r = 0.89**). During delayed harvest, visible mold on seeds increased markedly. Significant losses in seed germination were found at 1 and 2 weeks delayed harvest. Seeds infected with Fusarium moniliforme and Curvularia lunata were 60% lower in viability than noninfected seeds. Phoma spp. and Nigrospora sp. were associated with 20 to 40% reductions in seed viability. Colletotrichum graminicola did not lower seed viability of infected seeds. Sorghum rust severity varied from 0.6 to 46.6% among lines. All but 6 lines showed rust severity of less than 15%. Over all lines there was no significant correlation between rust severity and yield. Six rust susceptible lines (15 to 46.6% rust severity) yielded 63.8% ± 22.6 g/m2, whereas 6 of the most resistant lines (rust severity of less than 3%) yielded 126.6 ± 46.4 g/m2. Based on pest resistance, rapid grain fill and yield, IS 12610 der, IS 12661 der, and SCO(414-12) (ADN 252) appear to be excellent candidates for further testing at Mayagüez. In avoiding seed pests, sorghum lines appeared to benefit from a rapid germination and emergence, a comparatively long vegetative growth period, and a short uniform grain filling period.

Healthy Seed

Seed perform a vital role in agricultural sector for crop production as well as seed business. Scarcity of healthy seed hinder not only the crop production but also the quality of seed. Storing of healthy seed with proper storing condition is one of the suitable methods to maximize production however, healthy seed also lose its quality during seed storage. Seed remains viable for long time if the seed stored by maintaining seed moisture content, storage temperature with storage container. So, this experiment was carried out to observe the quality parameters of jute seed during long term storing. To find out the storage effect an experiment was conducted on march, 2020 at seed laboratory, Jute Agriculture Experimental Station, Jagir, Manikganj, Bangladesh during the period of January 2016 to March, 2020. Plastic pot was used in this experiment as a storage container to store jute seeds. Three tossa jute (C. olitorius L.) varieties viz., O-795 (V1), O-9897 (V2) and OM-1 (V3) were used in this study. Result revealed that storage period and jute variety showed significant effect on different seed quality parameters. The highest seed germination, field emergence, seed vigour and the lowest 1000-seed weight, moisture content were recorded in T5 (2019-20) treatment. On the other hand, the lowest seed germination, field emergence, seed vigour and the highest 1000-seed weight, moisture content were recorded in T1 (2015-2016) treatment. Furthermore, seed germination, field emergence, seed vigour was negatively but 1000-seed weight was positively correlate with moisture content. Results revealed that extended storage period caused the decreasing seed quality and seed can be stored for three years in plastic container without hampering the seed quality.

The use of pre-sowing organic hydration-dehydration techniques to improve quality and performance of organic seeds has already been lacking in the literature as well as in the organic farming regulations of different countries. Hence, this study was conducted to investigate the effects of organic hydration (hydropriming and organic priming) and dehydration treatments on germination and early seedling growth in organic tomato seeds. Following each priming treatment, the seeds were surface dried and divided into two sub-groups. First part of the seeds was taken to the germination tests immediately while the second part was dried back until the original seed moisture content was reached before the germination tests were set up. Then, responses of organic tomato seeds to organic hydration and dehydration treatments were observed on the bases of viability (normal germination rate) and different vigour parameters such as mean germination time, germination index, seedling dry weight and seedling vigour index. When the overall data were assessed, the best results were obtained from the hydropriming and organic priming with 250 ppm seaweed extract solution followed by both dehydration treatments in organic tomato seeds. Consequently, these results suggested that hydropriming and organic priming could be used both in seed and seedling industries to improve organic seed quality and performance. Furthermore, the results indicated that the addition of these organic hydration-dehydration protocols to the current procedures of the regulations of organic tomato production could be a useful strategy.Key words: Lycopersicon esculentum, Ascophyllum nodosum, hydropriming, organic priming, seed viability, seed vigour

Abstract. Efendi M, Handayani A, Lailaty IQ. 2019. Short Communication: Seed germination of twelve Indonesian begonias for conservation. Biodiversitas 20: 1192-1197. Knowledge of seed quality is essential when seeds are stored for the long term. A preliminary study on Begonia seed conservation was conducted, to characterize morphology and germination testing on native Begonia from Indonesia. As many as 12 species of Indonesian Begonia were observed for the characteristics of fruit and seeds. Later, we tested the level of seed viability at different levels of fruit maturity. The experimental design used a Completely Randomized Design (CRD) with two factors. Data analysis was performed using the Statistical Tool for Agricultural Research (STAR) program and further testing the Duncan Multiple Range Test (DMRT) at a 5% significance level. Generally, all seeds were barrel-like in shape, the smallest size in B. muricata (252.42 µm length), and the largest size in B. areolata (up to 451.42µm length, while the operculum 28.48 µm-104.9 µm length). Most Begonia seeds start germinating in the second and third weeks after sowing. B. scottii, and B. verecunda, as well as B. longifolia, showed germination in the second week, while other species tended not to be simultaneous. Dry seed germination was higher than seed wet for eight weeks. B. longifolia and B. scottii had the highest germination in wet seed treatment: while in the dry seed treatment, the highest germination was showed by B. areolata and B. muricata.
