Seed priming (controlled hydration followed by drying) is used to alleviate high temperature inhibition of germination and improve seedling emergence of lettuce (Lactuca sativa L.) and other species. However, seed priming can also reduce the longevity of seeds during dry storage. Alternative drying methods [i.e., slow drying or moisture content reduction (MCR) before drying] can extend seed lon...

chamomile (matricaria recutita) is a highly valuable medicinal and aromatic plant of asteraceae family and its anthodia used frequently in pharmaceutical and cosmetic industries. the aim of this study was the evaluation the effect of drought stress induced by polyethylene glycol 6000 (peg) on germination percentage, germination rate, plumule and radicle length of four improved cultivars of germ...

the effects of priming treatment using five osmotic solutions (peg, manitol, kno3, kh2po4 and combination of two salts) in six osmotic potentials (-1 to -1.5 mpa) was studied on germination percentage, rate and uniformity of melon seeds. the best results were obtained with high concentrations of kno3 and lower concentrations of manitol. mean germination time of melon seeds in 19°c was preceeded...

A series of experiments were conducted in laboratory at The University of Agriculture, Peshawar to determine the optimal duration and maximal concentration of zinc (Zn) and phosphorus (P) for priming wheat seed. The seeds were soaked through a range of durations (0, 12, 18, 24, 36 and 48 h) and tested for germination as surface dry and dried to original moisture (12%). Seed soaked for 18 h resu...

in arid and semi arid, seedling emergence and establishment are key stages for final plant density in chickpea production. drought stress, especially at the end of the growing season, is one of the factors which decrease a main part of chickpea grain yield in these areas. therefore the aims of this study were assess to the effects of hydro priming and hormonal priming by gibberellin and abscisi...

Screening and identification of tolerant genotypes using osmotic materials under in vitro culture could be rapid, easy, even accurate. In this research, three Iranian landraces Cucurbita sp. included Tanbal Ajili (Cucurbita maxima Duch.), Razan pepo L.), Balghabakhi moschata Duch.) seeds were cultured ¼ MS medium. After germination, plantlets transferred to media containing mannitol PEG 6000. M...

Priming of legume seeds before sowing was performed by Roman farmers in order to increase the germination rate and synchronize germination, as reported naturalist Gaius Plinius Secundus. Several centuries later, this technique is still used for a wide range species. However, measure be successfully production, it necessary find solution successful storage primed seeds. The potential soybean det...

Cadmium (Cd) is considered one of the most toxic heavy metals to living organisms, being very persistent in soil and non-biodegradable, thus posing a long-term hazard plants humans. In recent years, application different molecules at seed level, known as chemical priming, has been studied method improve stress tolerance plants. present study, we tested effect hydro-priming proline priming lettu...
