“…Minimum seed vigor was registered in a3b3 variant (priming with SA 0.75 mM + PEG 25%). These data are in accordance with the ones listed by Sharafizad et al, (2013). Control variants presented the highest values of measured characteristics while in medium to high concentration of PEG decreased significantly because the grains could not absorb this solution.…”

The present paper analyses the effect of pre-treatment with salicylic acid (SA) on germination and the growth of winter wheat seedlings in water stress conditions induced by polyetylene glycol (PEG). A two-factor experiment was conducted in a completely randomized projection. The first factor (A) included three levels: a1-distilled water -control; a2 -0.25 mM SA; a3 -0.75 mM SA and the second factor (B) included three levels: b1-distilled water; b2 -15% PEG and b3 -25% PEG. Biological material was represented by a DH winter wheat line. It were made observations on germination percentage (GP), root length (RL), cotyledons length (CL), seedling fresh weight (SFW) and vigor index (VI). After the analysis of the obtained results it can appreciate that the 25% PEG concentration played the main role for the significant decrease of the germination percentage (GP) and vigor index (VI). Also, seeds pre-treatment with 0.75 mM SA could be a way to improve germination characteristics in drought conditions.

“…reported that increasing SA concentration enhances ABA synthesis which can inhibit seed germination. Sharafizad et al (2013) reported that pretreatment of wheat seeds with high concentrations (1.2 and 2.7 mM) of salicylic acid, compared to a low concentration (0.7 mM), reduced hypocotyl length. Accordingly, Zadehbagheri (2014) reported that pretreatment with high SA concentration (3 mM) damaged seed germination and seedling growth of corn while lower concentrations improved them in stress conditions.…”

In order to investigate the effect of seed priming with ABA and SA on germination indices of sesame in saline conditions, an experiment with three factors and four replicates arranged in completely randomized design. The first factor was type of growth regulator as ABA and SA, the second factor was concentration of growth regulator including 10, 50 and 500 ppm and the third factor was NaCl salinity (0, 2, 4, 6 and 8 dS/m). Seeds were soaked for 6 hours in distilled water, ABA or SA solutions, after which the solution was eliminated and the seeds were dried, deposited in separate Petri dishes between two filter papers and watered. During a 10-day period, germinated seeds number were counted daily and at the final day, randomly selected seedlings were weighed (fresh and dry) and their plumule and radicle lengths were recorded. The results showed that salinity decreased germination rate (GR) and uniformity (GU), but 10 and 50 ppm ABA or SA supply induced higher GP and GU at 4 dS/m and above, more pronounced at 8 dS/m. SA with 500 ppm concentration; however, impaired seed viability. On the contrary, plumule and radicle lengths of seeds primed by 10 and 50 ppm ABA and SA tended to be lower at 0, 2, 4 and 6 dS/m and higher at 8 dS/m than non-primed control. Almost similar results were obtained for seedling dry mass, although the effects of SA were more drastic. Overall, the results suggest a considerable ameliorative effect of ABA and/or SA seed pretreatment on germinability of sesame seeds under salinity but seedling growth may be retarded which is probably an acclimation and temporary response to salinity stress.

“…Hundred healthy seeds for each treatment were selected manually by hand picking method. Various growth attributes such as Seed germination, Coefficient of velocity of germination (CVG), Germination rate (GI), Germination rate index (GRI), Coleoptile length, Root length, plantlet fresh and dry weight was calculated according to method given by Sharafizad et al(2013). In order to measured detail (CVG, GI, and GRI):CVG is characterized by speed and acceleration of germination and calculated from the following equation (Maguire, 1962).…”

In order to determine the effect of moisture content, storage time and pesticide (fungicide & insecticide) application in wheat variety Bezostaja -1, an experiment was conducted in Split-Split plot, randomized complete block design with three replications for two years at Ankara University. The main plots have three seed moisture levels viz. standard, standard +1.5% and standard + 3 percent at the time of disinfect application. The Split plots (sub plot) have treatments like seed storage time viz: 0, 1, 2 and 14 months and sub-sub plot was pesticide application and types and pesticide level. In this study two pesticides viz. Diaconazole (% 1), Chlorpyrifos -ethyl (% 25 w p) was used either individually or in combination. Various wheat characters which studied in present study are Coefficient of Velocity of Germination (CVG), Germination Index (GI), Germination Rate Index (GRI), Coleoptile length, Root length, Fresh weight and Dry weight. Result of study revealed that interactions between pesticides, seed storage and seed moisture content have significant effect (1%) on the various studied growth characteristics such as CVG, GI, GRI, Shoot length, root length, fresh weight and dry weight. Further, it was reported that the traits such as seed germination percentage, germination index, fresh weight and root length have very higher efficiency in the maintenance of seed for one to two months at the application of anti-fungal toxins with 9.5 % moisture Content. While minimum storage efficiency was reported when combination of pesticides (fungicide + insecticide) were applied at 12.5% moisture.
