wheat gave maximum value for growth and yield parameters. Pre-sowing seed treatment of mung been cultivar of K in pyridoxine solution significantly enhanced leaf nitrogen, phosphor and potassium concentrations at different growth stages, and seed protein concentration at harvest . In our knowledge, responses to seed. Wheat plant density, spikes, biomass, and yield all increased as seed size and seeding rates increased. Averaged across all other factors, the use of higher seeding rates and larger seed sizes improved yields by 12 and 18%, respectively. Accordingly, grain yield was more highly correlated with seed size than with seeding rate effects.
of results about the seed vigor in the wheat culture. Thus, the goal of this work was to evaluate the effect of the vigor level of wheat seeds, submitted to different sowing densities, on seedling emergence, tillering and the yield performance of the culture. Material and Methods The experiments were developed during the harvest. Effect of Seed Size and Density on Winter Wheat Performance Larry D. Robertson Winter wheat is the most important crop in Kan sas, seeded annually on approximately million acres. Any production practice 'that influences yield of this crop is important Little work has been done in Kansas on selection of wheat seed or on the influence.

Within a genotype, seed that has a higher protein content and/or is larger will produce more vigorous seedlings and sometimes higher yields. Spring and winter wheat seed collected from five cultivar trials grown at several different locations were used to determine the relative effect of genotype and environment on seed protein and seed size.
Seed were obtained from a N fertility experiment, sieved into seven size classes, and analyzed for protein. Seed protein content varied from approximately 8 to 16%. Within each seed lot the largest seed had approximately a % higher protein percentage than the smallest seed.
In growth chamber experiments seedling vigor was significantly increased by seed weight and percent protein. Therefore, sowing large seed should help reduce soil erosion by producing plants with greater ground cover. Similarly, large seed should increase the amount of forage for producers who sow winter wheat early as a prelude to grazing livestock.
Key words:Triticum aestivum, forage, seed size, soil erosion control, seedling vigorCited by: enriched soil, seed protein content had little effect on seedling growth. The beneficial effects of seed protein content are more clearly expressed under stress conditions and are more evident when plant growth depends on the nutrients available from the seed.
During initiation of germination, temperature influences the expression of the protein effect. Based on size, the seeds are classified as very large, large, medium, small and very small. This variation is due to flow of nutrients into the seed at the mother plant. Since seed coat and embryonic axis are the first to develop in a seed within a pod and accumulation of food reserve is occur later one.
Within a genotype, seed that has a higher protein content and/or is larger will produce more vigorous seedlings and sometimes higher yields. Spring and winter wheat seed collected from five cultivar trials grown at several different locations were used to determine the relative effect of genotype and environment on seed protein and seed size, and these factors were related to the dry weight of seedling shoots (vigor).
The effect of seed protein content on seedling vigor has been studied in many species, such as wheat, barley and oats 4,12,13, Effect of seed size on seedling vigor and forage production of winter wheat.

Other studies about the role of seedlings vigor on other plant`s characteristic showed that seed size was effected the stand establishment and total yield of wheat (Guillen-Portal et al., ; Stougaard and Xue, ; Lafond and Baker, ).
Harvesting after full physiological stage causes reduce seed yield and seed quality of wheat (PUCARIĆ & UJEVIĆ ). There are many ways of characterizing seed quality, but the main indicators of quality are seed size and seed efficiency. These two seed quality traits of wheat are in positive correlations with seedling vigor and growing in the.

The advantages of large seeds may be better expressed in moisture-stress environments, where planting depths also play a. Four greenhouse experiments were conducted to study the influence of seed size, protein content and cultivar on seedling vigor of wheat measured as seedling dry weight at 20 days.
The simple and partial correlation coefficients among the variables were all positive and significant. No significant interaction occurred between seed size and genotype.
Seed sizes were smaller than mm, mm, mm and bigger than mm. The seed density of each group was seeds m The trial was performed according to. Seed characterization. From each seed lot, seed size was determined by counting the number of seed per kg and converting average seed mass into mg seed − protein and oil content were quantified by non-invasive, time-domain proton-nuclear magnetic resonance (1H NMR) as described previously (Horn et al.,Snider et al., ).Briefly, chemometric algorithms were developed for.
Grain yield was similar at a seeding rate of 50 and seeds m It was higher when 4 and 2 g N m-2 were applied at active tillering and jointing, respectively (4–2N), than when no N was applied at these stages (0–0N).
However, it was not influenced by N application rate at anthesis. Grain protein content was similar at 50 and seeds m It was higher in 4–2N than in 0–0N. A series of seed priming experiments were conducted to test the effects of different pretreatment methods to seed germination, seedling growth, and seed yield traits in maize (Zea mays L.).Results indicated that the seeds primed by gibberellins (GA), NaCl, and polyethylene glycol (PEG) reagents showed a higher imbibitions rate compared to those primed with water.
seedling establishment at the transcriptome level remains unknown. Here, we report that wheat seeds produced under different nitrogen levels (N0, N, N, and N) showed signiﬁcant differences in seed vigor and seedling establishment.
In grain yield and seed vigor, N0 and N treatments showed the minimum and maximum, respectively. N EFFECT ON WHEAT GRAIN QUALITY / Int.
Agri. Biol., Vol. 4, No. 4, Grain Vigor Final germination percentage. The most important vigor evaluation test is germination percentage of seeds. wheat yield under dry land condition (Paul and Choudhury, ).
According finding above, seed priming has positive effect on germination, emergence, seedling growth and yield in wheat. Dell-Aquila and Tritto () reported that primed seeds emerged 12h earlier than non primed seeds. This may be due to increase in activity of. seeds coated in this way resulting in slow adoption of seed coating technology in agriculture.
The present study analyzed the effects of seed coating on germination, which seed coat composition can enhance germination rate and early vigor and why, the effects of seed coat on germination and seed physiology, and which influence seed coats. In germination stage, decreased wheat (Triticum aestivum L.) seedling growth (mg per seedling) as affected by drought and salinity stresses is a well-known heterotrophic seedling growth can be defined as a product of two components: (1) the weight of mobilized seed reserve (WMSR; mg per seed), and (2) the conversion efficiency of utilized seed reserve to seedling tissue (mg.Abstract.
Seed size and weight are important criteria for determining seedling vigour and stand establishment. Evolution of seed dry weight of wheat (Triticum aestivum L.) during germination and early growth was examined because poor stands are often associated with the depletion and exhaustion of seed laboratory experiments were conducted on filter paper and in soil at three.Introduction.
In India, Wheat (Triticum spp.) is the second most important winter cereal after rice that contributes substantially to the National food security by providing more than 50% of the calories to the people who mainly depend on it. 1 Drought adversely affects plant growth and development, seed germination, 2, 3, 4 seedling growth, 5 enzyme activity, 6 DNA, RNA, protein synthesis 7.
