Radish Seed

<p>Glucosinolates (GS) are amino acid derived secondary metabolites present specifically in Brassicaceae family. The effect of altitude (2800 m - 4000 m) on GS contents and seed quality characteristics in radish (Raphanus sativus L.) was investigated. The total GS in radish seed was 147.5±21.5 μmol/g DW, which included five aliphatic and four indolic GS compounds. Increasing altitude was related linearly to increase in total GS contents (R2 = 0.759). Among individual GS, glucoraphanin and glucoraphenin showed consistently increasing trend with altitude. Increasing altitude is related linearly to increase in 100 seed weight (R2 = 0.266) and seed yield per plant (R2 = 0.849). A steady decreasing trend was observed in seed moisture content (R2 = 0.831) and siliqua length (R2 = 786) with increasing altitude. Altitude of plant origin was positively correlated with GS contents (r = 0.900, p≤ 0.01), seed weight per plant (r = 0.919, p≤ 0.01) and geometric mean diameter (r = 0.661, p≤ 0.01), and negatively correlated with siliqua length (r = -0.880, p≤ 0.01), moisture content (r = -0.884, p≤ 0.01) and seed vigour index (r = -0.547, p≤ 0.01). Our results indicate that the concentration of GS in radish seed and seed quality traits can be significantly increased by growing plants at higher altitude.</p>

ABSTRACT The feasibility of extending the storability of fresh hot pepper seeds, by modifying the storage atmosphere, using the respiration inhibitors and seed desiccants was examined. Halogens such as chlorine, bromine and iodine and methanol, ethanol and potassium permanganate were used for a period of 22 months under accelerated ageing conditions of high seed moisture and temperature. The various seed quality parameters - viability, vigour, speed of germination, seedling dry weight, and moisture content were evaluated. In the untreated control, decreased seed viability was observed within 10 months of storage. However, iodine and chlorine were proved effective in retaining high seed viability up to 90.7 and 88.0%, respectively, even after 22 months of storage. Chlorine treatment was able to retain the seed vigour (904.0), iodine (766.4), KMnO4 (754.4) and methanol (566.7) whereas the value of vigour index in control was 72.0. Chlorine and iodine were on par in their ability to maintain the speed of seed germination (25.2 and 24.8, respectively), followed by KMnO4 (20.2). Seedling dry weight was proved as a parameter not sensitive in estimating the seed quality since even after 22 months storage of seeds at atmospheres of chlorine, iodine, KMnO4 and methanol did not show any differences. KMnO4 sharply reduced the seed moisture content from 9.83 to 7.89% providing better storability over the control.

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.

Time Of Harvest

Trials on the cultivars Canyon and Gallatin 50 in 1978 and Cascade in 1979 were run in North Queensland to examine ways of improving seed quality of snap beans. The trials concentrated on the maturation period, since this is a critical period for the development of seed quality. We found that seed quality was poor when the crop was cut at the stage when the leaves had fallen and all the pods were dry, or if the plants were cut at any stage and allowed to dry on the ground in single rows. This poor seed quality was associated with high pod temperatures during seed maturation. Cutting the crop before leaf fall, at a seed moisture content close to 50% (20-40% of pods dry) and windrowing immediately in 5 or 10 rows to 1 windrow gave low pod temperatures during seed maturation and high seed quality. Seed harvested and threshed directly off the crop was of good quality provided the seed moisture content in the crop had fallen to less than 25%.

Abstract Several physical properties of three safflower cultivars (IL-111, LRV51-51 and Zarghan279) at moisture contents of 10, 15, 20 and 25% were determined and compared. All the linear dimensions, geometric mean diameter and sphericity of safflower seeds increase linearly with increase in seed moisture content. The values of geometric properties were higher for IL-111cultivar than the LRV51-51 and Zarghan279 cultivars. The values of the bulk densities decreased, whereas the thousand seeds mass, true density and porosity were increased with increase in seed moisture content. All the gravimetric properties for the three cultivars of safflower were significantly different (p<0.05). The values of the terminal velocity for all cultivars were significantly increased as the moisture content increased. The terminal velocity for the three cultivars of safflower were significantly different (p<0.05). On the two different surfaces, the coefficient of static friction of the IL-111 cultivar was significantly greater than that of the other cultivars. The static coefficient of friction was higher on plywood and lower for galvanized steel. The values of the angle of repose increased with increase of the moisture content. The values of the angle of repose for Zarghan279 cultivar were higher than the IL-111, LRV51-51 cultivars.

The present investigation was carried out in laboratory of the Department of Seed Science and Technology, College of Agriculture, Junagadh Agricultural University, Junagadh from August, 2013 to June, 2015, wherein two kg of freshly harvested quality seed of mungbean cv. GM 4 having high germination percentage and low moisture content (below 8%) was taken for each repetition and given the treatments. The experiment was carried out using completely randomized design (CRD). After proper mixing or smearing, seeds were packed in 500 gauge polythene bags and kept in laboratory under ambient condition. Observations were recorded at bimonthly 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 indicated that all the treatments exhibited significant difference for all the traits studied except shoot length after two years of storage. The Indian Minimum Seed Certification Standards in mungbean for germination percentage is 75 per cent. Looking to the germination percentage and Seed vigourindex I and II, among all the treatments, T1 (Neem Seed kernel powder @ 5 g/kg seed), T2 (Neem seed kernel powder @ 10 g/kg seed), T3 (Neem Cake @ 5g/kg Seed) and T4 (Neem Cake @ 10g/kg Seed) recorded the higher values for these traits and can be recommended as a seed treatment before storage for maintaining the seed germination and seedling vigour for more than two years.

An experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during April 2013 to June 2013 to study the effect of three storage containers (tin container, polythene bag and cloth bag); and five storage periods (0, 15, 30, 45, and 60 days) on the seed quality of soybean. The experiment was laid out in Completely Randomized Design (CRD) with four replications. The soybean seeds stored in tin container showed maximum germination capacity with high germination index, highest seedling growth, seedling dry weight per plant and vigour index. The seeds stored in cloth bag had the lowest seed quality during the testing period. The highest 1000-seed weight, moisture content, electrical conductivity, abnormal seedlings and number of dead seeds were recorded in cloth bag; where the equivalent lowest values were recorded in tin container. The moisture content, 1000-seed weight, electrical conductivity, number of abnormal seedlings and dead seeds were increased with the longer period of storage. In addition, germination index, seedling growth, dry weight per plant of soybean seedling, and vigor index decreased with the increase in storage period. Among the three containers, tin container was the best and the cloth bag was the worst storage container for soybean seed storage for long period.
