In order to evaluate the effect of seed priming on some effective physiological parameters on seed germination of pea (Pisum sativum L.) under chilling stress, a factorial experiment was conducted in completely randomized design with four replications. Treatments were consisted of priming treatments (hydropriming, halopriming, osmopriming and no priming) and temperature (3, 6, 9, 12 and 15 ˚c)....
background & aim: because of seed germination ability of medicinal plants seed is low and, generally exposed to problem. priming is one of the techniques that help seeds to be germinated faster and uniformly. experimental: a laboratory experiment was carried out on germination and growth improvement in heracleum persicum desf. by seed osmo-primming in seed technology laboratory ...
To evaluate the interaction of Cd and SA on seed germination of Safflower (Carthamus tinctorius L. cv. Soffe), this experiment was carried out as a factorial based on CRD with four replications in 2012, in Yasouj University seed lab. Factors included of four levels of seed priming with SA (0, 0.3, 0.6, and 0.9 mM) and eight levels of cadmium nitrate (0, 5, 10, 15, 20, 25, 30 and 35 mM). In all ...
Hormonal priming to overcome drought stress and aging damage in groundnut seed (Arachis hypogaea L.)
Groundnut seed priming was performed with an aqueous solution of gibberellic acid (GA3) (0, 50, 100, and 150 ppm for 18h) and accelerated aging (96 h) was done prior to drought stress (-0.4, -0.6, and -0.8 MPa), then recovered. Investigated traits were germination percentage, mean germination time, germination rate, vigor index, plumule length, radicle length, seedling length, malondialdehyde c...
In order to investigate the effects of priming methods on the improvement of seed germination indices and seedling growth of Lallemantia (Lallemantia Iberica) under different salinity levels, two factorial experiment in a randomized complete block design were carried out in the seed technology laboratory of Agricultural Sciences and Natural Resources University of Khuzestan in 2018-2019. In the...
Background & Aim: Because of seed germination ability of medicinal plants seed is low and, generally exposed to problem. Priming is one of the techniques that help seeds to be germinated faster and uniformly. Experimental: A laboratory experiment was carried out on germination and growth improvement in Heracleum persicum Desf. by seed osmo-primming in Seed Technology Labora...
تاثیر هیدروپرایمینگ بر ویژگیهای جوانهزنی و رشد گیاهچه گلرنگ (Carthamus tinctorius L.) تحت تنش خشکی
Priming is an effective method to improve seed viability that might be resulted to increase of seed germination percent and germination rate under stress conditions, such as drought stress. So, in this research the effect of seed priming on seed germination characteristics of safflower were evaluated under drought stress. A factorial experiment based on completely randomized design (CRD) with t...
The effect of different pre-sowing seed treatments and sowing dates on germination and rootstock quality of ber was assessed to standardize a combination which could yield optimum germination and quality rootstock. Of the fourteen pre-sowing treatments, highest seed germination and best seedling growth was obtained in T10 x D2 (seed soaking in water for 48 hours followed by 6 days storage in mo...

For the purpose of evaluating the effect of chitosan on seed germination and some biochemical characteristics of the milk thistle herb in the conditions of salinity, an experiment was conducted as factorial in a completely randomized design (CRD) with three replications in the Laboratory of Seed Science and Technology of Shahed University, Tehran in 2015. Experimental factors comprised salinity...
