Seed Vigour

High planting seed mass and total nutritive reserves (oil and protein) have a positive impact on early seedling vigor. With treatment of any good Biological molecules helps to grow seed fast and vigourously.

Biological molecules helps seed to accelarate to physiological process to ignite seed germination.

Seeds developed under moisture stress, nutrient deficiency, extreme temperatures, etc. often result in light, shriveled seed or collectively called poor-vigor seed. Application of Biological molecules helps.

Seed vigor is a quantitative character controlled by multi-genes. Genetic and quantitative trait locus (QTL) analyses on seed-vigor trait in model plants, such as Arabidopsis and rice, are mostly concentrated on related morphology traits, whereas few physiological traits have been researched and prooved that external application of Biological molecules play vital role.

Primed seeds imbibe and revive metabolic activities soon after sowing resulting in increased germination rate, higher germination uniformity, faster emergence and vigorous seedlings. Moreover, pre-sowing seed priming leads to crops growing faster and yielding higher due to development of tap root & fibrous root in enough quantity.

Germination rate and seedling vigour index values increased with the increase of seed size suggesting the selection of larger seeds for good stand establishment.

During germination externaly applied Biologicals helps, the fats are hydrolyzed into fatty acids and glycerol by lipase enzyme. Fatty acids are further converted into acetyl – COA by the process of ? - oxidation. The acetyl COA is further converted into sucrose via glyoxylate cycle and is transported to the growing embryonic axis.

The germination potential and seedling vigour was significantly more in the large and medium size than the ungraded and smaller ones respectively. First count germination, plumule and radicle length, speed of germination, dry matter production and seed vigour index positively correlated with seed size.
