priming is one of the seed enhancement methods that might be resulted in increased seed performance (germination and emergence). the objective of this research was to evaluate effect of priming on seed emergence and yield under wide ranges sowing dates in cotton. treatments were combinations of 6 sowing dates and 2 seed treatments (control and primed seeds). hydropriming method was used; seeds ...

This study was conducted to study the effects of different priming methods on germination rate and percentage under salinity stress and to determine the stability of primed seeds. In order to accomplish this, three different experiments were conducted separately, including the experiment of water uptake, the experiment of salinity stress, and the experiment of storability of primed seeds. Primi...

to answer this question that if osmopriming improve germination indices in salinity-affected seeds of pinus eldarica medw., a factorial experiment in randomized completely design was carried out with three replications. osmotic treatments were applied in 5 levels (-2, -4, -6 and -8 bar for 72 hours and non-primed) by polyethylene glycol (peg) and salinity treatments in 8 levels (0, 40, 80, 120,...

Seed priming is a commercially successful practice, but reduced longevity of primed seeds during storage may limit its application. We established a series of experiments on rice to test: (1) whether prolonged storage of primed and non-primed rice seeds for 210 days at 25°C or -4°C would alter their viability, (2) how long primed rice seed would potentially remain viable at 25°C storage, and (3...

Seed priming is one of the most important techniques used to improve seed germination under biotic and abiotic stresses. For this purpose, germination and seedling growth characteristics of primed seeds of Tall wheatgrass (Agropyron elongatum (Host.) P. Beauv) were evaluated under drought and low-temperature condition. A factorial experiment was conducted on the basis of randomized completely b...

Seed priming is a successful practice to improve crop establishment under adverse environment. However, reduced longevity of primed rice (Oryza sativa L.) seeds during storage limited the adoption of this technique. Present study investigated the effect of temperature, relative air humidity (RH) and oxygen on the longevity of primed rice seeds in a range of 60 days storage. In addition, the bio...

effect of seed priming on germination and seedling growth of sesame investigated under controlled conditions. the primed seeds with znso4 had the maximum germination percentage whereas the highest germination rate was observed in hydro-primed seeds. the treated seeds with peg showed the best growth of the seedlings and rootlet. the complementary field experiment was conducted to evaluate the ef...

A laboratorial study was carried out to investigate the effect of NaCl priming on seed germination and seedling growth of canola. Canola seeds were primed with 1% NaCl solution for 24 hours, at 20°C. Then primed and non-primed seeds were irrigated with seven different saline solutions consisted of 0 (control), 0.25, 0.50, 0.75, 1.00, 1.25 and 1.50% concentrations of NaCl. Results indicated that...

The Ellis-Roberts seed viability equation is accepted as an accurate predictor of seed longevity over a range of storage temperatures and moisture contents (MC). One application of this model is to identify different combinations of seed MC and temperature that can result in similar seed storage lifetimes. The present study was conducted to determine whether the reduction in storage life of pri...
