Nutripriming with zinc sulphate and borax for early growth and seedling vigour in grain cowpea [Vigna unguiculata (L.) Walp] The experiment was conducted at Coconut Research Station, Balaramapuram with an objective to study the effect of nutripriming with ZnSO4 and borax on the early growth and seedling vigour and Zn and B content in grain : Anju B Raj, Sheeja K Raj, K. Prathapan, N.V. Radhakrishnan. The primary metabolism and associated biochemical changes occurring in seedlings emerging from primed and non primed seeds subjected to NaCl and polyethylene glycol (PEG) stressed conditions was analyzed to study the effect of halopriming on osmotic stress tolerance potential of green gram varieties with varied tolerance potential to NaCl and by:
Seed priming involves taking seed through the early stages of the germination process. In the above chart, the green line corresponds to a standard germination process: during the phase 1 (imbibition), under suitable temperature and moisture, seed takes up water. 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 by:
Agronomic biofortification by seed treatments is a convenient way to harvest improved yields of micronutrient-enriched grains. This 2-year field study was conducted to evaluate the effects of seed priming with zinc (Zn), boron (B) and manganese (Mn) alone and in combinations on stand establishment, grain yield and biofortification of bread wheat (Triticum aestivum L.). Seeds of wheat cv Cited by: 5. During seed maturation and germination, major changes in physiological status, gene expression, and metabolic events take place. Using chlorophyll sorting, osmopriming, and different drying regimes, Brassica oleracea seed lots of different maturity, stress tolerance, and germination behavior were created. Through careful physiological analysis of these seed lots combined with gene .

Several seed priming approaches including hydropriming, nutrient priming, hormonal priming, chemical priming, osmopriming, and redox priming can be effectively used under different environmental : Sadam Hussain, Saddam Hussain, Abdul Khaliq, Shafaqat Ali, Imran Khan.
To understand the molecular and biochemical mechanisms of osmopriming-induced salinity tolerance, the accumulation of proline, gene expression and activity of enzymes involved in proline.
Seed osmopriming treatment allowed wheat plants to maintain a greater relative growth rate during the drought period, resulting in higher dry matter and grain yield production relative to non.
ABSTRACT Osmopriming has a positive effect on the enhancement of seeds germination and seedlings growth, especially under stress conditions. This study investigated the effects of osmopriming with polyethylene glycol on alfalfa (Medicago sativa L.) seeds germination and seedlings antioxidant responses under drought stress.

Sunflower (Helianthus annuus L.) seeds show more germination at high temperatures (25–30°C) than at temperatures below 20° by: Osmopriming is the most common method of priming used by solutions with low osmotic potentials.
In this method many compounds have been used to achieve a solu-tion or known water potential and include salt salts such as NaCl, K 2HPO 4, KNO 3, MgSO 4, KH 2PO 4 and low molecular weight polymers such as glycerol and mannitol and largeAuthor: Alemzadeh Ansari, Sasan Aliniaifard.
From the present study it may be concluded that seed priming may enhance the seedling vigour of mungbean. Nutrient priming using phosphorous and osmopriming with mannitol were the most efficient priming treatments in this study. In further research work biochemical basis for the enhanced phenology of mungbean may be evaluated.
REFERENCES. Seed priming is a pre-sowing treatment which leads to a physiological state that enables seed to germinate more efficiently. The majority of seed treatments are based on seed imbibition allowing the seeds to go through the first reversible stage of germination but do not allow radical protrusion through the seed coat.

In both osmopriming and hormonal priming treatments, the highest number of tillers and productive tillers were from pre-germination.
The tallest plants from osmopriming were from mM treatment, while 50 ppm GA 3 had the tallest in hormonal priming. The highest tiller efficiency for osmopriming was from mM and and mM sodium chloride, while in hormonal priming it was ppm salicylic acid.
It integrates advances in the diverse and rapidly-expanding field of seed science, from ecological and demographic aspects of seed production, dispersal and germination, to the molecular biology of seed development. The book offers a broad, multidisciplinary approach that covers both theoretical and applied by: In leek seeds, Ashraf and Bray () reported that replicative DNA synthesis and nuclear DNA had occurred during osmopriming and germination of leek seeds.
