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.

Abstract In order to study the plant growth regulator, using salicylic acid (SA) on germination and growth indices for laboratory research in crop year 2014-2015, which was conducted at the research center Safiabad-Dezful, Khuzestan province. The treatments included four levels of priming with salicylic acid {control (distilled water), 0.7, 1.2, 1.7 mM} in a completely randomized design in three replications. The results showed that the control treatment reduced the decrease in germination time. The highest percentage of germination and related characteristics of the control (distilled water) was obtained. Seed vigor and seedling vigor index were reduced in high concentrations of salicylic acid. The germination percentage of an average daily germination, seed vigor and seedling vigor index had a positive and significant correlation with the daily germination rate showed a significant negative correlation. The results of comparison of treatments showed that the treatment concentration of 0.7 mM salicylic acid highest (22.3 days) and control (distilled water) lowest (0.3 day) had mean germination time. Effects of priming showed the highest mean daily germination (15.44) related to the control and the lowest (2.97) related to the concentration of 7.1 mM salicylic acid. Also, the results showed that the 1.7 mM salicylic acid treatment had the highest number of germinated seeds per day (0.3880) and control treatment had the least number of germinated seeds per day (0.6467). The highest vigor index was observed in control treatment with seedling length of (8.15 cm) and the lowest vigor index was observed in 1.7 mM salicylic acid treatment with seedling length of (1.54 cm). The highest seedling vigor index was observed in control treatment (33.58) and the lowest seedling vigor index was observed in 1.7 mM salicylic acid treatment (17.20). The coefficient velocity germination rate in control treatment was highest (3) and in the 1.7 mM salicylic acid treatment was lowest (0.15). The correlation coefficient between vigor index and seedling vigor index has the highest value (98%). There was a positive correlation between germination percentage and mean daily germination and there was a negative correlation between germination percentage and daily germination speed.

Corinne Kraus, Ute Knobloch, Scherer Waltraud, Peter Christian Endler Interuniversity College for Health and Development Graz / Castle of Seggau, Austria Background In 1926, an influence of a homeopathically prepared high dilution of silver nitrate on the growth of coleoptiles of wheat seedlings was described (Kolisko 1926). Later, in an extensive series of experiments, wheat was observed under the influence of extremely diluted agitated silver nitrate (10e-23, “24x”). Stalk lengths clearly indicate that development is enhanced by the probe silver nitrate 24x as compared to control (Scherer et al. 2015). A preliminary experiment was performed in early autumn 2015 on stalk growth of wheat seedlings treated with (not potentized) dilutions of silver nitrate 10e-6 to 10e-10 (“6e to 10e”), compared to potentized silver nitrate 6x to 10x (N = 100 per group). A clear, albeit not statistically significant trend was observed of 6x-stalks being longer (23.4 + 16.2 mm) than 6e-stalks (13.0 + 10.9 mm). Objective The aim of this study was to investigate the influence of diluted versus potentized low dilutions of silver nitrate (10e-2 to 10e-10) on wheat germination. Method The experiments were performed in late autumn 2015 on wheat grain (Triticum aestivum L., Capo variety). The grains were observed under the influence of aqueous solutions 10-2 to 10-10 part per weight of silver nitrate, either diluted in steps of 1 : 10 in distilled water by mere pipetting (probes “2e – 10e”), or diluted and agitated in steps of 1:10 (to create potentized probes “2x – 10x”). Untreated distilled water (“w”) served as an additional control. All probes were applied blindly. 100 grains were observed per treatment group in each of the groups resulting a total of 2,000 grains. Grains were placed in glass dishes, probes were added and dishes were covered with lids and placed in drawers . The following endpoint criteria were defined: K1 = visible emergence of sprout material, K2 = lifting of the operculum and emergence of the sprout and W1 = development of three roots.   Result Germination rates K1 of seedlings treated with “w”-probes (blue), with “e”-probes ranging from 2e to 10e (black) and with “x”-probes ranging from 2x to 10x (red) at the measuring points 20h, 24h and 28h (from left to right for each of the probes). In K1, K2 and W, there is an obvious increase of germination rates from the high to the lower concentrations of silver nitrate, both in the “e” and in the “x”-groups and observable at 20h, 24h and 28h (p < 0.01). In contrast, germination rates of the two „w“-probes are practically alike (p > 0,05) When “e” and “x”-data are compared, germination rates are higher under the influence of “x” than under the influence of “e” (p < 0.01 for the pooled “x”-values compared to the pooled “e”-values with regard to K1 as well as K2 as well as W). Conclusion: A significant difference was found between wheat grains treated with mere dilutions compared to grains treated with potentised dilutions. References 1.

ABSTRACT Wild piquin pepper fruits are consumed and traded because of their flavor, nutritional and pharmaceutical properties. The heterogeneous germination of its seeds has caused pregermination treatments to be unstandardized. Because of that, our goal was to evaluate pregermination treatments of piquin pepper seeds from a wild plant from the municipality of Victoria, Tamaulipas, Mexico, consisting of immersion for different periods (2, 24, 48 h) in solutions with variable concentrations of the growth regulators naphthalene acetic acid (NAA; 0.1, 1.0, 2.5 mM), salicylic acid (SA; 1.0, 5.0, 10 mM), gibberellic acid (GA3, 1.0, 5.0, 10 mM), indole-3-butyric acid (IBA; 1.0, 2.0, 3.0 mM), the commercial product Biozyme (Bioz) containing minerals and growth regulators (Bioz; 0.5, 1, 2%), and sulfuric acid (H2SO4; 2, 5, 10%) in a completely randomized design, using distilled water as the control. For each treatment, we measured the imbibition ratio, germination percentage, time to obtain 50% germination (T50), and coefficient of variation of germination time (CVt). Our results showed that the imbibition was similar in the control and the treatments, but it differed between treatments. The highest imbibition recorded in 48 h was 87%. The highest germination percentage (79.2%) was achieved with 2 h immersion in 2% Bioz, followed by 1 mM NAA (62%) and 5 mM SA (56%). T50 and CVt were 10-26 d and 0-39%, respectively. According to our results, we concluded that the pregermination treatments we assayed improved the physiological potential for the germination of piquin pepper seeds.

In this study, the effect of five different levels of salt (NaCl) on the germination of Phaseolus vulgaris L. seed was investigated. Laboratory experiment with completely randomized design comprising three replicates in Petri dishes was conducted at Gaziantep University Vocational School of Higher Education in Nurdagi to determine the salt effects on common bean germination. The germination of the cultivar (Tegmen) was studied using distilled water (control) and under osmotic potential of 0.3, 0.6, 0.9, 1.2, and 1.5 MPa NaCl. The results indicated that the Mean germination time (MGT), Germination index (GI), Coefficient of velocity of germination (CVG), Germination percentage (GP), and Seed vigor index (SVI) varied between 3.13 and 3.78 days, 6.88 and 3.93, 0.156 and 0.153, 90 and 60%, and 867.0 and 290.3, respectively. Significant differences were found among NaCl treatments in terms of GI, GP, and SVI. All the examined parameters were decreased with increasing NaCl concentration, except MGT. The max and min GI, GP, CVG, and SVI were observed at the control condition (0.0 MPa) and highest osmotic potential (1.5 MPa) of NaCl, respectively. Correlation coefficient between all possible combinations was estimated and the results indicated that MGT, GI, GP, CVG, and SVI had significant positive or negative correlation with each other.

Vriesea incurvata is a native bromeliad from Brazilian Atlantic Rainforest and commercialized as an ornamental pot plant. The morphological characteristics of its floral scape may also indicate it as a new product to use as a cut flower. However, its postharvest behavior was unknown. This study was conducted to determine its vase life by applying distilled water (control) and solutions containing sucrose (50 g L-1), salicylic acid (50 μM), and citric acid (50 g L-1) for periods of 8 and 24 h. Floral scapes maintained in solutions showed vase life greater than 16 days when compared to the control (distilled water). However, solutions with sucrose evidenced the best behaviors related to the maintenance of physiological and aesthetic features during the vase life of the floral scapes. It is concluded that solutions with sucrose, salicylic acid, and citric acid applied for 8 and 24 h extend the vase life of the V. incurvata floral scapes. Sucrose applied for 8 h promotes the maintenance of color, brightness, and turgidity; improves water balance, and reduces the relative fresh weight losses of floral scapes throughout the vase life, extending their longevity up to 24 days.

Seed priming is known for its promoting effects on seed and seedling properties under stress conditions such as salinity, temperature and drought stresses. Poor plant stand establishment is a common problem for marigold production. Therefore, an experiment was conducted to investigate the effect of different seed priming techniques on calendula seed germination and seedling enzyme activity. For this purpose, different seed priming techniques: hydropriming (distilled water, 24 and 72 h), osmopriming (0.02% or 0.04% KNO3 for 24 and 72 h) and hormonal priming (100 or 500 mg L-1 GA3 for 24 and 72 h) were assessed. Seeds without any treatment were considered as control. Compared with control, 100 mg L-1 GA3 and distilled water for 72 h showed the highest promoting effects on germination percentage. The highest vigor index (525.75) was related to hydropriming (for 24 h) treatment. Also, the maximum root length was found with 0.02% KNO3 for 72 h. Catalase significantly increased in the primed seeds. The highest CAT activity and total soluble sugars were found in the seeds primed with 100 mg L-1 GA3 for 72 h. Moreover, the enzyme activity was significantly higher in the distilled water and KNO3 treatments compared with the untreated seeds.
