Science research ». Environmentally friendly gardening. Plant health. International Journal of Agricultural Research, v. Indeed, the sowing of mixed seeds of a species may result in a non-uniform stand establishment, what may lead to heterogeneity in the plant vigor and size Mishra et al. Tree growth, biomass and productivity of wheat under five promising clones of Populus deltoids in agrisilviculture system. International Journal of Ecology and Environmental Sciences, v.
Distinct seed sizes have different levels of starch and other energy reserves which may be an important factor to improve the expression of germination and initial growth of seedlings Shahi et al. How seed size and water stress affect the seed germination and seedling growth in wheat varieties? Current Agriculture Research Journal, v. Germination depends on the ability of the seed to use reserves more efficiently Bewley et al. Seeds: physiology of development, germination and dormancy. New York: Springer, Germination characteristics and mobilization of seed reserves in maize varieties as influenced by temperature regimes.
Journal of Agricultural and Rural Development, v. Effect of seed size and drought stress on germination and seedling growth of naked oat Avena sativa L. Bulgarian Journal of Agricultural Science, v. However, these results vary widely between the crop species and the germination and growth environment. In general, large seeds have a higher seedling survival rate, higher growth and better field performance than small seeds, under non-stressful environments Ambika et al. Review on effect of seed size on seedling vigour and seed yield.
Research Journal of Seed Science, v. Mechanisms of salinity tolerance. Annual Review of Plant Biology, v. Water shortage and salt excess in the soil at the sowing time cause delayed and reduced seed germination, unequal seedling emergence and unsatisfactory stand establishment Steiner et al. Drought tolerance of wheat and black oat crops at early stages of seedling growth.
Effect of delayed emergence on corn grain yields. Journal of Plant Nutrition, v. Drought and salinity affect germination by creating highly negative water potentials, thus preventing the seed water uptake. However, the negative effects of drought and salinity on seed germination and plant establishment can be alleviated or potentiated with the use of different seed sizes.
Research results have reported that the effects of seed size on germination and seedling growth under water and saline stress conditions are still controversial and inconclusive. Germination, seedling growth and relative water content of shoot in different seed sizes of triticale under osmotic stress of water and NaCl. African Journal of Biotechnology, v. On the contrary, Pereira et al. Influence of seed size and water restriction on germination of soybean seeds and on early development of seedlings.
Journal of Seed Science, v. On the other hand, Soares et al. Limede et al. Effects of seed size and sowing depth in the emergence and morphophysiological development of soybean cultivated in sandy texture soil. Australian Journal of Crop Science, v. However, the effects of seed size on the germination and growth of peanut seedlings under stressful environments are still unknown.
Thus, this study aimed to investigate the effects of seed size on the seed germination and initial growth of peanut Arachis hypogaea L. Peanut Arachis hypogaea L. The harvest was manually performed at days after sowing, and the plants were air-dried at room temperature for 96 h. The seeds were extracted by hand, weighed and then separated into three size classes: i small seeds, with mass of 0.
To compare the effects of salt or water stress on germination and seedling growth, the seeds of each size class were exposed to The osmotic potential of polyethylene glycol Plant Physiology, v. The concentration of NaCl to obtain the osmotic potential of Soil and water: physical principles and process. New York: Academic Press, As a control, a solution with osmotic potential of 0.
Four replicates of 25 seeds from each size class were evenly distributed between two sheets of paper towel moistened with distilled water control , PEG or NaCl solutions of Thiram was added to the solutions at a concentration of 0.
Effect of salt and osmotic stresses on the germination of pepper seeds of different maturation stages. Brazilian Archives of Biology and Technology, v. Seeds were considered germinated when the primary root was longer than 5. Germinated seeds were recorded at 5 days first germination count test and 12 days total germination percentage after starting the test Brasil BRASIL.
The shoot and primary root length were measured in 10 normal seedlings randomly obtained after the total germination count 12th day using a meter scale, with results expressed in cm. The results were expressed in mg seedling To determine the root:shoot ratio, the obtained root dry matter was divided by the shoot dry matter. The data of germination percentage, seedling length and dry matter production were used to calculate the seedling vigor and salt or drought tolerance indices.
Vigor determination in soybean seed by multiple criteria. Crop Science, v. The analyses were performed using the Sisvar software, version 5. Sisvar: a computer statistical analysis system. The percentage of canola seeds that emerge to form plants is typically 50 to 60 per cent, but some growers have achieved 90 per cent in some fields. This article provides tips to strive for 75 per cent emergence and give each seed a better chance to contribute….
Enter seed size into canola calculator As you pick up canola seed, look at the thousand seed weight for each lot and run that through the seed rate calculator at canolacalculator. This will indicate the seeding rate required to hit your target stand. What is the ideal target stand for yield and profit?
