Pretreatment of seeds of seven wild plant taxa (viz., Gaultheria hookeri C. B. Clarke, G. stapfiana Airy Shaw, G. semi-infera (C. B. Clarke) Airy Shaw, G. trichophylla Royle var. ovata Panda & Sanjappa, Lyonia ovalifolia (Wall.) Drude var. ovalifolia, Pieris formosa (Wall.) D. Don and Vaccinium glauco-album C. B. Clarke) in the family Ericaceae using Na-dikegulac (Na-DK) for 8 hours (4 + 4 h in two installments) before keeping in ambient storage condition (32±2 ºC) for different durations (0 and 20 days) slowed down the rapid loss of germination and reduced the time (h) required for 50% seed germination (T50). Concomitantly, the reduction of protein level as well as the activity of catalase of seed kernels during storage period was ameliorated to a significant extent in the chemical pretreated seed lots.

Opis:
This study examined the effects of storage temperature and pre-chilling on the germination of the seeds of Solanum macrocarpon – which according to literature has a seed viability of 63.33%. In our study, the seeds were sown in dry Petri dishes and placed in the refrigerator set at 4 °C for 1, 3, 5, 7 and 10 days. Another set of seeds was placed in incubators set at 25, 35 and 45 °C for 40 days before the germination experiment was carried out on a laboratory workbench. Results from the study revealed that while storage temperature had a significant effect on that the germination of seeds of this plant, pre-chilling of seeds and incubator treatments generally reduced seed germination. Thus seed germination in this plant is temperature dependent.

Opis:
The effect of various scarification method on breaking seed dormancy and germination enhancement in Annona muricata (Magnoliales: Annonaceae) was examined in this study via: mechanical scarification with sandpaper, file and stone; chemical scarification with 10, 25 and 50% H2SO4 for 5 seconds respectively; exposure to wet heat (hot water) for 1, 3 and 5 seconds; exposure to cold treatment by chilling in refrigerator of 4 ºC for 12, 18 and 24 hours; soaking in coconut water for 5, 10 and 15min and untreated seeds as the control. The results of the experiment showed that chemical scarification with H2SO4 at 50% for 5 seconds had significantly highest percentage germination (60%). This was followed by the seeds soaked in coconut water for 15 minutes (39.69). Seeds treated with 25% H2SO4 for 5 seconds had 30% germination. Other treatment were less or not effective. Untreated seeds had the least percentage germination (6%) with mean germination time of 40.20 and germination index of 0.27. The treatments that gave significantly higher germination percentages also produce low Mean Germination Time (30.01) and increased Germination Index (12.26). These characters shows that chemical scarification with H2SO4 at 50% for 5 seconds was the most effective treatment to break dormancy and enhancing seed germination in this species as revealed in this study.

Opis:
The maintenance of seed viability over long periods of time in genebanks is a key element in conservation of plant genetic resources. In this work, data obtained at the Bulgarian National seed Genebank from the routine task of monitoring seed viability from soybean were analyzed. Differences between initial, first and second germination test after 11 and 34 years of long-term storage were assessed among 182 accessions from Glycine max (L.) Merr. The samples were regenerated during 1978-1981 growing seasons. On the basis of experimental data, the seed storage characters - σ, P50% and P10% were determined allowing the prediction of seed storage life and the regeneration needs. Significant decrease in seed viability after 11 years of storage was not recorded in the investigated soybean accessions from the different regeneration years. When comparing the initial germination percentages with results from the second control test after 34 years of storage were found significant differences in the loss of seed viability among genotypes from different regeneration years. The frequency of odd results were most significant for genotypes regenerated in 1981 (0.691) in comparison with these from other regeneration seasons. The highest Ki value (2.09) was recorded for accessions from 1981 harvest year; where rate of seed deterioration (1/σ) was also highest (-0.044). The lowest values both for Ki and 1/σ were found for the groups of accessions harvested in 1978 and 1979. There was a wide variation between groups of accessions regenerated in different years in both the time taken for viability to fall to 50% and the time for seed viability reduction with 10%. The predicted mean safe storage time for Glycine max (L.) Merr. was 25.54 years. Total 76 accessions or 42,2% of analyzed accessions had significant decrease of germination after 34 years of storage and would need regeneration.

Opis:
This study was carried out in Harrabot village of Tarkughat VDC, Paundi and Majuwa village of Sundarbazar Municipality of Lamjung district during 2015/2016. Thirty households (10 HH from each village) who were involved in seed production were purposively selected for survey. The respondents’ knowledge was gathered through focus group discussions and household surveys, using a pretested semi-structured questionnaire. Seed routine test was carried out in the Agronomy lab of Lamjung Campus. Results revealed that the dominant features of farming in the study areas were small land holdings, fragmented and sloping land with rainfall-dependent farming. Land distribution pattern was 12.93% marginal land, 16.35% upland and 70.72% irrigated lowland. Farmers grew rice, maize, mustard and pulses as major crops and fruits, vegetables, potato and flowers as minor crops. Major cropping pattern were Rice-Mustard-Maize, Maize-Rice-Fallow, Rice-Fallow-Rice etc. Nutrient-poor soils, low pH, farmers' poor access to inorganic fertilizers, soil-depleting cropping patterns, lack of technical knowledge on crop management, soil erosion and degradation are major challenges. Insects, diseases and weeds were major biotic constraints, while lack of irrigation, drought and lack of technical support were major abiotic constraints of rice production. Sukhadhan-2, Sukhadhan-3, Sukhadhan-4, Sukhadhan-5 and Sukhadhan-6 were planted in rain-fed lowland, whereas Ramdhan, Sunaulo sugandha, Loktantra, Sabitri and Makwanpur-1 were grown in irrigated lowland. Seed producers used 39.07% of the land for seed production with 4.78 tons ha-1 of seed productivity. Most of their produced seed was send to Sundar Seed Coop Ltd., Paudibazar, while some seed were stored in their home by using local containers such as earthen pots, plastic drums, metal bins, Dali, Kotho, Bhakari etc. The tested seed quality parameter in the lab showed that the average moisture, purity and germination percentage of the seed samples were 13.87%, 94.13% and 96.72%, respectively.

The effect of cryopreservation on seed germination and seed vigour, and seeds with different moisture regimes have been studied to find out if they are a good candidate for LN by storing seeds in liquid nitrogen (196 °C) for 24 and 72 hours from three rice seed cultivars, namely Lisem, Manen, and Mapok. For all the three cultivars studied, cryopreservation did not decrease germination percentages or seed vigour and it also appears that seed moisture content ranging from 10% to 18% is not a determining factor for the survival of seeds up to 72 hour storage of the seed in LN.

In the present investigation the seeds of Pigeon pea (Cajanus cajan (L.) Millsp) were treated with different doses of gamma radiation (05KR, 10KR, 15KR, 20KR, 25KR, 30KR, 35KR, 40KR, 45KR, and 50KR) and concentration of Ethyl Methane Sulphonate (05mM, 10mM, 15mM, 20mM, 25mM, 30mM, 35mM, 40mM, 45mM, and 50mM) for studying seed germination, seedling height, (shoot and root), seedling injury, seedling vigour index, and seedling survival of plants at 30th day. The seed germination percentage was decreased with increased in the concentration/doses when compared to control. The LD50 (Lethal dose) value was determined based upon the seed germination percentage. The 50 percentage of seed germination and reduction was observed in 20KR of gamma rays and 25mM of EMS and it is considered as LD50 value for both the treatments. The decrease in seed germination was more prominent with gamma rays than that of EMS treatments. The seedling parameters of gamma rays and EMS treated seedlings were progressively decreased with increase dose/concentration in all mutagenic treatments when compared to control. The maximum seedling parameters were observed in 05KR of gamma rays and 05mM of EMS. Minimum seedling parameters were observed in 50mM of EMS and 50KR of gamma rays respectively.

In recent years, the demand of chilli has tremendously increased due to its attractive market price and multifarious used in cooked and processed forms. At present people are much concerned about the fruit quality and yield. Therefore, attention is being paid for development of genotypes having high yield potential with desirable fruit quality characters in a short period of time. For this purpose, seeds of chilli were mutagenised with ethyl methane sulphonate (EMS) and diethyl sulphate (DES) to determine their mutagenic sensitivity in M1 generation. The increasing concentration of EMS and DES decreased in morphological and yield characters. The spectrum of mutation and induced variability for various quantitative traits were observed in M1 generation such as germination (%), plant height, primary and secondary branches per plant, days to first flowering, fruit length (cm), fruit girth (cm), total number of fruits per plant, number of seeds per fruit, seed weight per fruit (g), 100 seed weight (g) and pericarp: seed ratio showed variability in chilli with the effect of EMS and DES. The percentage of chromosomal abnormalities in different mitotic stages was significantly higher than that of the control in all the treatment concentrations.

Opis:
Green revolution increased the food production enormously to feed the geometrically growing population. In India, the availability and affordability of fossil fuel based chemical fertilizers at the farm level have been ensured only through imports and subsidies. Dependence on chemical fertilizers for future agricultural growth would mean further loss in soil quality. The possibilities of water contamination and unsustainable burden of the fiscal system. The Government of India has been trying to promote an improved practice involving use of biofertilizers along with fertilizers. These inputs have multiple beneficial impacts on the soil and can be relatively cheap and convenient for use. The agricultural chemicals like pesticide and weedicides were being used to save the standing crop from the attack of pests and to boost crop production. At the same time the excess use of chemical fertilizers degraded the soil properties. In this context, the farmers are expecting for the cheapest and eco-friendly alternative for getting higher yield. Biofertilizers is only the alternative way to get more production without harmful to environment. So the effect of different doses of biofertilizer (Rhizobium) on germination studies of Fenu-greek seed germination percentage, seedling growth, fresh weight and dry weight, chlorophyll, protein and soluble sugar content has been studied in the laboratory condition. There parameters increased to application when biofertilizer compared to control.

Chromium is one of the most common toxic metals present in the environment that induces various toxic effects in plants. A pot experiment was conducted to determine the effects of chromium on germination percentage, seedling growth, chlorophyll ‘a’, ‘b’ and proline content of Sesbania sesban (L.) Merr. The seedlings were treated with different concentrations of control, 0.10, 0.25, 0.50, 0.75 and 1.00 g kg-1 of chromium. The parameters such as germination percentage, root and shoot length, seedling fresh weight dry weight, chlorophyll ‘a’, ‘b’ and proline content of leaves were measured. Our results indicated that a significant inhibitory effect was observed at all levels of chromium compared to control. Increasing the concentration of chromium to 1.00 g kg-1 showed a significant decrease in seed germination, shoot and root length, fresh weight, dry weight and chlorophyll ‘a’ and ‘b’ content of plant. While proline, catalase and peroxidase contents were increased by increasing Cr concentration. It was also noted that accumulation of chromium in the roots was much higher than the shoots of the seedlings under treatment.

Salt stress is one of the most severe environmental factors that reduces and limits growth and development of plants. Abiotic stresses such as heavy metals, salinity, drought, temperature, UV-radiation, ozone causes drastic yield reduction in most of the crops. Especially salt stress affects around 20 of NaCl on germination and seedling growth of Zea mays L. Seeds of Zea mays were germinated in glass Petri- 100 × 15 mm diameter lined with blotting paper. Ten seeds were placed in each petri-dish. Petridishes were irrigated with 25, 50, 75, 100, 125, 150, 175 and 200 mM concentrations of NaCl. A control was moistened with ten milliliters of distilled water. The germination percentage, water absorption of the seeds, water uptake percentage and the growth parameters were observed. The results obtained showed that the inhibition of the germination percentage, germination rate, water uptake, growth and biomass accumulation of the seedlings were observed to decrease with increasing NaCl concentrations. At the highest level of stress both plumule and radical decreased significantly. The salt stress decreased seed germination, biomass and growth of maize seedlings due to ion toxicity, decrease osmotic potential and oxidative stress.

To compare the effect of NaCl, CaCl2 and their combinations on germination and early seedling growth stages of Lycopersicum esculentum L., were studied under pot experiments 2008. Results indicated that significant increases were recorded in percentage of germination, seedling fresh and dry weights, seedling length, water content, catalase activity and photosynthetic pigments (chlorophyll a, b and total chlorophylls as well as carotenoids) under the low level concentration (20 mM) of NaCl or CaCl and their combination (1:1). On other hand increasing salt concentration in nutrient solution caused significant decrease in all of these parameters. The great reduction occurred under high salinity level of NaCl (50 mM). Meanwhile, peroxidase activity increased significantly with increasing salinity levels from 20 mM to 50 mM of both applied salinity types. Besides, peroxidase activity under NaCl salinity showed a marked increase followed by NaCl + CaCl2 (1:1) and CaCl2 at 50 mM.
