Semantic priming refers to a tendency that language processing is facilitated in case that words are semantically related to each other due to a language user’s knowledge and prior experience. Hence, semantic priming can be considered as a tool to assess language processors’ implicit index of semantic relatedness. The purpose of the present study is to investigate 1) whether teenaged EFL learners will show semantic priming effects on gender category perception, 2) whether there are any different effects between immediate and delayed prime conditions, and 3) whether there are any different effects between gender stereotype and suffixtype words. As a result, semantic priming effects were observed in general. Delayed prime condition showed stronger effects than immediate prime condition and feminine suffix-type of words showed robust effects than any other types.

Background: The present study assessed the response of kenaf (Hibiscus cannabinus L., Jangdae) seed to NaCl and the effects of polyethylene glycol (PEG) on kenaf seed germination and vigor. Methods and Results: Seed germination ranged from 11.3% to 58.8% after 24 hours of immersion in NaCl concentrations from 0% to 0.5%. The priming treatments had lower electrical conductivity (EC) values for the seeds than for the control and a deteriorated palisade layer. Priming in 10% PEG for 48 hours increased the germination upto 96.3% in H2O solution and 98.8% in 0.3% NaCl solution compared to that of the control (78.8%). Germination synchronization, and shoot and root growth of the primed seeds were greater than those of the control. The T50 of the control in H2O and 0.3% NaCl solution was 22 and 28 times, respectively. After priming, nine times was sufficient to reach T50 in both solution. The mean number of days to germination (MDG) decreased from 1.43 days for the control to 0.55 days for 0% PEG in H2O solution and from 1.57 days for the control to 0.56 days for 0% PEG in 0.3% NaCl solution. The dry weight after the 10% PEG treatment was higher than that of the control. Conclusions: Taken together, 10% PEG treatment for 24 hours is recommended for kenaf seed invigoration before planting.

The main objective of this study was to increase the germination percentage of kenaf seeds with less number of times under non-saline and saline conditions. Therefore, the first goal was to assess the response of kenaf seeds to NaCl. The second goal was to evaluate the effects of KNO3 on kenaf seed germination. The germination percentage exhibited a decreasing tendency in germination rate. Plant dry weight was approximately 0.2 g in all treatments at 5 days after germination. As time passed, the electrical conductivity (EC) value of hydro-priming (HP) consistently increased by 8.7 mS/cm at 24 hours of immersion. However, seeds primed with KNO3 showed no difference in EC values even as times passed. Regarding the priming effect, priming in 100 mM KNO3 concentration for 12 hours increased germination up to 85% in H20 solution and in 0 mM KNO3 concentration upto 73.8% under 0.3% NaCl solution, compared to that of Control. Germination synchronization, shoot length, and leaf unfolding of primed seeds were greater than those of the Control. In addition, main root and hair roots appeared more rapidly in the treated seeds and were more abundant compared to that of the Control. The T50 (times to reach 50% of the final germination percentage) of the Control in both H20 and 0.3% NaCl solutions was 18 and 22 hours, respectively. However, when treated KNO3 priming (0 to 100 mM) in H20 and 0.3% NaCl solution, 9 hours was sufficient to reach T50. Primed (hydro-priming and KNO3) seeds had a lower MDG (mean days untill germination; 0.6-0.62) compared to that of the Control (1.13-1.31) in H20 and 0.3% NaCl solutions. Regarding dry weight of plants after priming, an increasing tendency after the priming treatment in the H20 solution was observed. Furthermore, no significant difference in plant dry weight under 0.3% NaCl stress was observed between the Control and primed seeds. Taken together, the results suggest that 50-100 mM KNO3 priming for 24 hours optimize seed germination rate in less number of times of exposure with great vigor. Therefore, it is recommended for kenaf seed invigoration before planting.

In nine commercial watermelon cultivars, the effects of osmotic seed priming were evaluated for seed viability and seedling growth at different germination temperatures and field conditions. Generally, primed seeds showed improved germination rate and reduced time for emergence at different germination temperatures, as compared to untreated seeds. In particular, priming effect on seed germination was significantly high at 15℃, which is an environment normally resulting in poor germination. Depending on the watermelon cultivar, germination rate under low temperature (15℃) was improved by up to 15~66% in primed seeds, as compared to untreated seeds. However, priming effect on germination was gradually reduced as the temperature reached to its optimum level for seed germination. Seed priming tended to improve the viability, fresh weight, and dry weight of watermelon seedlings, but its effect on seedling stage was not large, as compared to untreated seeds. Primed watermelon seeds showed improved emergence rate and facilitated germination in the field, but their seedling growth after 30 days from germination was not significantly affected. Our results indicated that seed priming can greatly improve the seed germination at poor temperature conditions in the watermelon.

Poor germination and labor intensive thinning of seedling after sowing are major deterrents in Setaria viridis production. Seed priming has the potential to improve the seedling emergence and economic feasibility by combined with seed coating for optimizing mechanized growing technologies to small cereal crops. The objective of this study was to determine the effective seed priming conditions on the improved germination in the laboratory. Seeds were hydro primed with distilled water for 6, 12, 24 hours and osmoprimed with PEG8000 (-0.15 MPa and -0.3 MPa), KCl (1% and 2%), KH2PO4 (0.5% and 1.0%), KNO3(1.0% and 3.0%), CaCl2 (1.0% and 3.0%) solutions for 6, 12, 24 hours at 15℃. Our results demonstrate that treating S. viridis seeds with PEG -0.3 MPa solution for 12h increased to maximum germination percentage to 97%, whereas the lowest germination percentage observed in seeds which treated with by CaCl2 1.0% for 24h and KCl 1% for 6h. Priming reduced the mean germination times (MGT) of all priming treated seeds statistically comparing to control. There was significant interaction between treatment and time. Further studies for field performance of primed seeds are needed.

This study was conducted to affirm the potential of seed priming techniques for optimizing mechanized growing technologies to maintain production of sustainable small cereal crops. Seed priming conditions were preliminary tested in laboratory. Sorghum seeds were hydroprimed and osmoprimed comprising a total of 33 treatments of different priming combination along with control. Seed primed in aerated solution of distilled water, PEG8000 (-0.15 MPa and –0.3 MPa), KCl(1% and 2%), KH2PO4 (0.5% and 1.0%), KNO3 (1.0% and 3.0%), CaCl2 (1.0% and 3.0%) solutions for 6, 12, 24 hours at 15℃. Maximum seed germination percentage, germination rate and reduced mean germination times (MGT) were observed when the seeds primed by CaCl2 1.0% for 24 h, whereas the lowest germination percentage observed in seeds which treated with KNO3 3% solution. Priming improved the MGT, germination index, and germination rate of all primed seeds statistically comparing to control. The MGT reduced by increase of treatment time. Further studies for field performance of primed seeds are needed.

The current study investigates the syntactic priming effects on sentence processing in Korean(L1) and English(L2) production through a measure of production time. The purpose of this study lies in investigating whether the priming condition facilitates the production process both in processors’ L1 and L2 production. Participants are 32 Korean native speaking (L1) university students who speak English as a second language(L2). The target structures were dative alternate structures: prepositional vs. double object dative structures in English and canonical(DAT-ACC) vs. scrambled(ACC-DAT) dative structures in Korean. The experimental paradigm involved the repetition of an auditory stimulus, followed by picture descriptions. The production time was measured by E-prime. As a result, while syntactic priming effects were observed both in L1 and L2 production, the syntactic primed condition did not reduce the production time in L1 utterances. However, the time was reduced in L2 utterances with failing in reaching to the statistically significant effects.

This study was carried out to select new pelleting binder and material for seeds from Fraxinus rhynchophylla Hance and Alnus sibirica Fisch. ex Turcz. The optimum treatments of the various concentrations and species of priming agents to improve seed germination of both woody medicinal plants were also estimated. Germinability was increased when the seeds of Fraxinus rhynchophylla Hance was soaked in -1.0 MPa of PEG6000 solution at 15℃ for 4 days significantly, the optimum treatment for improving germination of Alnus sibirica Fisch. ex Turcz was observed when the tested seeds was soaked in 100 mM of KCl at 15℃ for 4 days. The influence of physical and chemical properties of pelleting solid materials, the mixture of gypsum, diatomaceous earth, dalma ceramic and vermicuolite (6:1:1:1 ratio) were found as the best pelleting materials for Fraxinus rhynchophylla Hance and Alnus sibirica Fisch. ex Turcz. seeds. To satisfy the requirements of absorption and compatibility for multi-layer seed pelleting, SGPA (Starch-grafted cross-linked polyacrylates) hydrogel was prepared using starch, acrylonitrile, ceric ammonium nitrate, nitric acid, methyl alcohol and potassium hydroxide. The resulting SGPA hydrogel showed high water absorption but not plant compatibility. It suggested that seed pelleting using pelleting materials and SGPA hydrogel (multi-layer coating) after priming agent treatment is to increase germinability and seedling growth and it can reduced irrigation labours and can also save seed.

Direct seeding is increasingly being practiced by rice farmers under both rainfed and irrigated conditions. The trend is the outcome of a scarcity of labour required for transplanting, simplicity and additional benefits associated with direct seeding. Flooding slows seed germination, imposes fatalities and delays seedling establishment in direct-seeded rice. This study describes responses of contrasting rice genotypes subjected to flooding or low oxygen stress during germination and discusses of tolernace shown by certain cultivars. In expt, two tolerant('Khao Hlan On', 'Khaiyan') and two intolerant('IR 42', 'IR 64') genotypes were used for growth and survival measurements. To compare effects of priming, pre-germination and germination on anaerobic tolerant and intolerant lines. Length of the longest shoot was measured in seedlings grown under either a control or in flooded soil, and plant survival was calculated based on the number of seedlings that emerged from floodwater. All measurements were 21 d after sowing. Tolerant and intolerant genotypes had the same seeding survival under normal soil conditions. But survival of intolerant genotypes were lower than tolerant genotypes. Growth of tolerant genotypes were faster than intolerant genotypes. Among the treatment, treatment 3 was greater. Because treatment 3 emerged first from water. Among the after days 1, 3, 5, survival was highest in after day 1. The other side, To late seeding over time, survival decreased.
