The Impact

Seed size may influence seed germination, and seedling vigor. Few investigations are available about the effect of seed size on barley seedling vigor in Jordan. The present study was designed to investigate the impact of seed size on germination percentage, seedling dry weight, seedling vigor index, and germination percentage after accelerated aging in barley. Three seed sizes i.e. large, medium, and small (having diameter of > 2.75 millimeter, 2.5 - 2.75 millimeter, and less than 2.5 millimeter, respectively) were tested in the experiment. Seed quality for different seed size categories was evaluated in the laboratory by measuring seed germination, germination after accelerated aging, as well seedling dry weight and vigor index. Results showed significant differences for large seeds in germination percentages, seedling dry weight and vigor index. It may be concluded that large seed size of barley showed best quality.

Salinity is a major abiotic stress limiting mungbean production worldwide including Indonesia. Since mungbean plant is very sensitive to salt condition, selection of salinity tolerant genotypes becomes important for mungbean improvement. The objective of this study was to evaluate the tolerance of eight mungbean genotypes to salinity at seedling stage under different levels. The experiment was arranged in a randomized complete block design with two factors (mungbean genotypes and salinity levels) and triplicates. Observation variables were germination percentage, vigor index, germination rate, hypocotyls length, epicotyls length, root length, number of root, seedling fresh weight, and seedling dry weight. The result showed that increasing level of salinity concentration inhibited the speed of germination, germination percentage, vigor index, normal seedling fresh weight, and number of lateral roots. Murai and Vima 1 were identified as tolerant genotypes, while Vima-2 and MLGV 0180 were identified as salinity sensitive genotypes at seedling stage. Currently, mungbean varieties with special characters, such as saline-tolerant is not yet available. The availability of saline-tolerant variety of mungbean is a cheaper and easier technology for farmers to anticipate the expansion of the saline area. The tolerant genotypes may be further tested at the later stage to obtain promising genotype tolerant to salinity that effectively assist mungbean breeding program.

The experiment was conducted to investigate the seed quality of Indian spinach for three months stored at different containers (Plastic pot, polythene bag and cloth bag) during 2013-2014 at Seed Technology Laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur. The initial moisture content of the seed was 9.89% with 75.00% germination. However, after two months, the seed had a different range of increased moisture content with reduced germination percentage depending upon the packing materials. Among the three containers, seeds stored at cloth bag absorbed more moisture (14.36%) from surrounding atmosphere followed by the moisture content, 12.67% and 11.50% of polythene bag and airtight plastic pot, respectively. Seeds stored at plastic pot, polythene bag and cloth bag exhibited 65.00, 64.00 and 50.00 per cent germination, respectively. Similarly, the fresh weight and dry weight of seedling and seedling vigor were also decreased. The seeds of plastic pot were good in term of germination capacity, fresh and dry weight and vigor index in comparison to those stored at cloth bag and polythene bag.Int. J. Agril. Res.

Effects of four different levels of NaCl (05, 10, 15, 20 dS/m) on the seed germination of cluster bean (Cyamopsis tetragonoloba L.) cultivars were investigated. Only distilled water was used in the control. The experiment was conducted in the Petri dishes under laboratory condition and laid out in CRD comprising five replicates. The results indicated that the germination index (GI), seed vigor index (SVI), germination stress index and seedling length (radicle and plumule) decreased with increase of salinity levels and germination percentage (GP) was reduced significantly at the highest level of salinity (200 mM). However, mean germination time (MGT) and time taken for 50% germination (T50) increased by increasing salinity levels. Correlation coefficient between all possible combinations was estimated and the results indicated that GP, GI, MGT, T50, and SVI had significant positive or negative correlation with each other.

The discharge of contaminated mining and industrial residues has become a major cause of environmental pollution. Seed is highly protective against external metal stresses. But they are highly sensitive during vegetative developmental process. In this study, germination was conducted in Macrotyloma uniflorum var. Madhu, in order to find out the effect of chromium toxicity on germination, growth and biochemical variations. The seeds were germinated in five different concentrations of chromium (25ìM, 50ìM, 100ìM, 150ìM and 200 ìM) solution. The hydroponically grown plants revealed the toxic phenotypic expression (root length, shoot length, seedling length, shoot vigor index, shoot fresh weight, shoot dry weight, root fresh weight and root dry weight) of plant after 3 growth stage (15 d, 30 d and 45 d). Similarly biochemical characteristics as well as antioxidant activities (Chlorophyll, carotenoid, carbohydrate, reducing sugar, catalase, proline content and peroxidase) were studied to see the toxic effect of chromium.

Abstract Crop performance is seriously affected by high salt concentrations in soils. To develop more new seed pre-sowing treatment technologies it is crucial to improve the salt tolerance of seed germination. Here we isolated and identified the strain Bacillus sp. MGW9 and developed the seed biostimulant MGW9 (SB-MGW9) by the strain. Effect of seed biopriming with SB-MGW9 in maize (Zea mays L.) under saline condition were studied. The results showed that the Bacillus sp. MGW9 has the characteristics of salt tolerance, nitrogen fixation, phosphorus dissolution, indole-3-acetic acid production and the like. Seed biopriming with SB-MGW9 enhanced the performance of maize during seed germination under salinity stress to improve the germination energy, germination percentage, shoot/seedling length, primary root length, shoot/seedling fresh weight, shoot/seedling dry weight, root fresh weight and root dry weight. SB-MGW9 biopriming also alleviates the salinity damage to maize by improving relative water content, chlorophyll content, proline content, soluble sugar content, root activity, activities of superoxide dismutase, catalase, peroxidase and ascorbate peroxidase, decreasing the malondialdehyde content. Especially, the field seedling emergence of maize seeds in saline-alkali soil can be improved by SB-MGW9 biopriming. Therefore, maize seed biopriming with SB-MGW9 can be an effective approach to resist the inhibitory effects of salinity stress and promote seed germination and seedling growth.

Laboratory, greenhouse, and field studies were conducted to determine the allelopathic potential of lantana and Siam weed on the germination and growth of five crops. Emergence and dry weight of bioassay species were affected when lantana or Siam weed debris was present on the soil surface or incorporated into the soil. However, presence of Siam weed on the soil surface did not affect dry weight of rape. Emergence and dry weight of crops (except emergence of spinach) were not affected when crops were grown in soil samples collected from beneath field-grown lantana. Dry weight of Chinese cabbage and chilli was reduced when these crops were grown in Siam weed-contaminated soil. Germination of Chinese cabbage, chilli, and rape decreased progressively when exposed to increasing concentrations of aqueous lantana extract. However, the lantana extract at full strength (66.7 g L−1) did not reduce germination of spinach and cucumber seed. Siam weed extract, when applied at full strength to seed of spinach, Chinese cabbage, rape, and chilli, reduced germination by 10, 12, 21, and 19% of control, respectively. Full-strength extract of lantana and Siam weed decreased seedling length and fresh weight of all crops.

Abstract Nanotechnology is an emerging field of science widely exploited in agriculture in recent years. In this investigation, application of nanotechnology in agriculture via application of some nano-particles (nano-iron and nano-silicon) have been investigated in seed priming of dragonhead. Seeds were subjected to pre-hydration treatments by factor nano-silicon dioxide as; (S1) 0 mM or distilled water, (S2) 1 mM concentration and (S3) 2 mM concentration and and factor nano-iron oxide as; (F1) 0 Mm or distilled water, (F2) 1 mM concentration and (F3) 2 mM concentration. Germination percent, root fresh weight, shoot fresh weight, root length, shoot length, dry weight of the seed residue, root dry weight and shoot dry weight were measured. Analysis of variance showed significant variation for the main effect of nano-silicon dioxide as well as nano-iron dioxide in root length and dry weight of the seed residue. The interaction effect of nano-silicon × nano-iron priming treatments were significant in all of the measured traits except germination percentage and root fresh weight. The highest germination percentage was recorded in S2-F3, S3-F1 and S3-F3 while the root fresh weight was high in S2-F3 and treatments S1-F1 following to S2-F3 and S3-F2 produced the highest shoot fresh weight. Also, S2-F3 has the highest root length (16.1 cm) and the highest shoot length (18.4 cm). The best treatment combination suitable for obtaining of high values of germination characteristics of dragon-head was identified as S2-F3 (1 mM nano-silicon dioxide plus 2 mM nano-iron dioxide).
