The present investigation was carried out from July 2013 to July 2015, wherein 100 g of fresh quality seed of onion cv. GWO 1 was having high germination percentage and moisture content below 8 per cent. The treatment consisted of two storage conditions (C) viz., C1 (Ambient temperature) and C2 (Cold storage at 70C + 20C); two packing materials (P) viz., P1 = Cloth Bag and P2 = Polythene Bag (500 gauge = 125 µ), and five seed treatments (S) viz., S1 = Control, S2 = Carbendazim @ 2g/kg seed, S3 = Mancozeb @ 2g/kg seed, S4 = Thirum @ 3g/kg seed, and S5 = Neem leaf powder @ 10g / kg seed. After proper mixing or smearing the seeds as per the treatments, seeds were packed and stored as per treatments. Observations were recorded at 90 days interval on viability and vigour parameters. The results revealed that seed stored under cold storage (7±2 °C) and in polyethylene bags (500 gauge) noted significantly higher values for all the characters even after two years of storage. All the treatment combinations of seed stored under cold storage gave more than 70 per cent germination (As per ISTA standard) even after two years of storage, of which, seed treated with thirum @ 3g/kg seed was the best treatment. Therefore, it can be concluded that seed of onion can be stored up to two year in cold storage packed in polyethylene bag without or with seed treatment without deterioration in germination and seedling vigour.

The present investigation was carried out in laboratory of the Department of Seed Science and Technolo-gy, College of Agriculture, Junagadh Agricultural University, Junagadh from the April 2013 to April 2015, wherein two kg of freshly harvested quality seed of soybean cv. Gujarat Junagadh Soybean 3 having high germination percentage and low moisture content (below 8%) was taken for each repetition and for each combination of treat-ments. The treatment consisted of two storage conditions (C) viz., C1 (Ambient temperature) and C2 (Cold storage at 7oC + 2oC), and five seed treatments (S) viz., S1 = Control, S2 = Carbendazim @ 2g/kg seed, S3 = Mancozeb @ 2g/ kg seed, S4 = Neem leaf powder @ 10g/kg seed, and S5 = Neem Oil @ 5 ml/kg seed. The experiment was carried out using Completely Randomized Design (Factorial) repeated three times. After proper mixing or smearing the seeds as per the treatments, seeds were packed in cloth bag and kept in laboratory under two different storage conditions. Observations were recorded at 90 days interval on germination (%), root length (cm), shoot length (cm), seedling dry weight (g), seed vigour index I, seed vigour index II and seed moisture content (%). The results revealed that storage condition (C) and seed treatments (S) exhibited significant differences almost for the all the traits for germination and seedling parameters after 2 years of storage. The results of soybean seed stored in two different storage conditions showed that on an average, the seed stored under cold storage (70C + 20C) noted higher values for all the traits studied except seed moisture content after 2 years of storage. Among the seed treatments, on an average, after 2 years of seed storage, significantly (P<0.05) higher values were recorded by all the seed treatments over the control. However, seed treated with Mancozeb @ 2g/kg of seed recorded the significantly highest germination percentage (71.50 %) and it was at par with Neem leaf powder @ 10 g / kg seed (70.67%) and Carbendazim @ 2g /kg seed (69.67%) after 2 years of storage. The germination percentage noted in control treatment was 33.17 per cent after 2 years of storage. An ISTA standard for germination in soybean is 70 per cent. Most of the interactions effects were found significant (P<0.05) for all the traits studied.

Background: Onion (Allium cepa L.) is a major bulbous vegetable as well as condiment of family Alliaceae grown in India, originated in Iran and Pakistan. Seed pelleting is a mechanism of applying various materials to the seed that can enhance the seed quality with respect to physiological, physical and health attributes. Seed deterioration during storage is inevitable process; however seed pelleting can reduce the rate of deterioration. The leaf powders possess antioxidant, fungicidal and insecticidal properties that helps in maintaining the seed quality during storage. Methods: The present investigation was carried out in the laboratory of Department of Seed Science and Technology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during the seasons of 2016-17 and 2017-18. This experiment comprised of pelleted seeds with different botanicals carried out to determine the effect of seed pelleting and storage potential of pelleted seeds. Result: This experiment comprised of pelleted seeds with different botanicals. In all the treatments gum Arabica (5%) was used as the adhesive except control. The pelleted seeds with different material were stored at ambient conditions for nine months. Highest germination (81.75%), seedling length (11.20 cm), seedling dry weight (1.82 g), seedling vigour index- length (920.33), seedling vigour index- mass (148.90) and speed of germination (26.57) were observed in onion seeds pelleted with Azadirechta indica leaf powder + clay and Melia azadirechta leaf powder + clay. Among the storage periods, fresh pelleted seed (0 month) showed maximum values with respect to germination (86.50%), seedling length (13.38cm), seedling dry weight (2.02 g), seedling vigour index- length (1154.50), seedling vigour index- mass (173.52) and speed of germination (29.04).From the present studies, it can be concluded that onion seeds pelleted with Azadirechta indica leaf powder + clay and Melia azadirechta leaf powder + clay showed significant effects for enhancing seed quality during storage.

A trial was conducted to investigate the germination percentage and emergence potential of nine imported temperate forage germplasms at the National Animal Production Research Institute, Shika, Nigeria. The seeds consisted of seven grasses namely; Beefsteak plant (Fructus perillae), Sweet elephant grass (Pennisetum alopecuroides), Wild foxtail millet (Setaria viridis), Napier grass (Pennisetum purpureum), King grass (Pennisetum sinese), Chinese sorghum (Sweet sorghum) and Zea mexican schard (Purus frumentum) and two legumes namely; Chinese woad (Isatis tinctoria) and Chinese alfalfa (Medicago sativa). A laboratory germination test and pot emergence trial was carried out to ascertain their viability. The result of the experiment showed that Sweet elephant grass, napier grass and king grass recorded over 90 % germination and the least was 30 % in Chinese sorghum. Chinese alfalfa and wild foxtail millet had least germination percentage with 100 % Seed dormancy.Highest emergence rate, seedling length and seedling vigour indexwere observed in king grass than the other forage germplasms. The highest percentage emergence was obtained in king grass > sweet elephant grass > napier grass > Zea mexican schard > beefsteak plant > Chinese woad > Chinese sorghum, respectively. It was concluded that these forages can successfully be adopted as animal feed resources in Nigeria and therefore, recommended formulti-locational trials in all the ecological zones of the country.

This study aimed to assess the effect of genetic diversity on physiological quality of soybean seeds stored in cold chamber and under environmental conditions. Ten cultivars were assessed in a randomized factorial design (2x10). Factor 1 corresponded to two storage conditions and factor 2 to ten soybean cultivars, with four replications. The evaluated variables were total germination (G%), first count of germination (F%), percentage of abnormal seedlings (AS%), germination speed index (GSI), water content (WC), electrical conductivity (EC), dry matter of seedlings (DMS) and length of seedlings (LS). Data underwent ANOVA, followed by Scott Knott test, as well as multivariate analysis of genetic diversity. The results showed a higher physiological quality for seeds under cold storage. Half of the cultivars (FPS Júpiter, FPS Urano, FPS Antares, FPS Netuno and CD 250) presented high germination rates and seed vigor, being thus indicated as high-standard materials for further breeding programs. Besides that, storage environment had influence on the clustering of soybean cultivars. Moreover, cultivars had genetic dissimilarity for almost all assessed traits as G%, GSI, F%, AS%, EC, DMS and LS.

The objective of this study was to evaluate the effect of controlled atmosphere (CA) on quality preservation of ‘Laetitia’ plums, mainly on internal breakdown, in order to determine the best CA storage conditions. Two experiments were carried out one in 2010, and another in 2011. In 2010, besides cold storage (CS; 21.0 kPa O2 + 0.03 kPa CO2), the fruits were stored under the following CA conditions (kPa O2+kPa CO2): 1+3, 1+5, 2+5, 2+10, and 11+10. In 2011, the fruits were stored under CS and CA of 1+0, 1+1, 2+1, and 2+2. The fruit stored under different CA conditions had lower respiration and ethylene production, better preservation of flesh firmness, texture and titratable acidity, lower skin red color, and lower incidence of skin cracking than the fruit in CS. In 2010, the fruit under CA with 2+5, 1+5, and 1+3 had a pronounced delay in ripening, although it exhibited a high incidence of internal breakdown. In 2011, the CA conditions with 2+1 and 2+2 provided the best delay in ripening and a reduced incidence of internal breakdown. The best CA condition for cold storage (at 0.5°C) of ‘Laetitia’ plums is 2 kPa O2 + 2 kPa CO2.

Forage grass seed quality is influenced by plant genetics as well as seed density, storage conditions, age of seed, and endophyte infection status. We used eight seed lots of tall fescue (three cultivars, with natural endophytes, endophyte-free, or novel endophyte) to test the effect of seed density on germination and seedling vigour. Seed lots were separated into nine density fractions using a cylinder air column. Thousand seed weight values were determined. Three runs of four replications of plots consisting of 25 seeds of each entry were seeded in greenhouse experiments to determine seedling mass at 8 weeks after planting. Early germination counts as well as laboratory germination tests indicated significant differences among weight classes in speed of germination as well as seedling vigour. The lightest fraction of seed clearly contained inferior seed, but higher density seed lots tended to have better germination and seedling vigour than lower density ones.

The continuous rise in global population demands more food production under limited land resources accompanied by climate change. More oversupply of quality seeds to meet ever-growing food demand is a highly challenging task. Seeds with low vigour level limit the growth and yield of crops at varied field conditions. Hence, an experiment was conducted to develop a technique for the fast and homogeneous growth of kabuli chickpea seeds. The priming treatments evaluated in the present study enhanced the various seed quality parameters of kabuli chickpea significantly when compared to control. Hydro-priming for 4 hours (at 20°C) and air drying for 72 hours showed better results compared to rest of the treatments both in fresh seeds which recorded higher first count (66.38%), germination (92.50%) root length (11.85 cm), shoot length (6.16), mean seedling length (18.01), dry seedling weight (747 mg), seedling vigour index-I (1665), higher speed of emergence (0.3992) and old seeds with higher first count (61.88%), germination (74.13%) root length (8.15 cm), shoot length (5.85 cm), mean seedling length (14.00 cm), seedling dry weight (611 mg), seedling vigour index-I (1056), higher speed of emergence (0.3814). The aged seeds have recorded 29 % increase in germination percentage in contrast to 8 percent increases in fresh seeds. Kabuli chickpea seeds could be subjected to hydropriming, an affordable, alternative, and eco-friendly technique for improving seed and seedling vigour of kabuli chickpea.

Hydration And Dehydration

Soybeans undergo rapid deterioration due to its chemical composition and unfavourable storage conditions. The objective of the research was to determine the length period of seed hidration and dehydration which is integrated with rhizobateri to viability and vigor of deteriorated soybean seed.  A completely randomized design with four replicates were used in this experiment. Seeds were treated with varied combination of hydration period in a rhizobacteria suspension and followed by dehydration time.  Data were analysed using the F-test and significant differences were further tested with Least Significant Difference at the 5% level. Results showed that the hydration and dehydration period of seeds in a rhizobacteria suspension improved viability and vigor of seed which have 59.5% initial germination percentage. The improvement was 12.28%, 0.56, 25.4% and 1.4 days for standard germination test, vigor index, first count test percentage and T50, respectively. The hydration for 60 minutes followed by dehydration for 60 minutes gave the best results on seed viability and vigor.
