“…It is very important to determine the right dose. As reported by several authors (Rybinski, 2002;Gladyszewska, 2009;Hernandez-Aguilar et al, 2009;Sacala et al, 2012) the laser irradiation leads to a lower frequency of very severe or milder injuries. Serious injuries can be prevented by various, mostly low doses of irradiation (Qing-he Li et al, 2012).…”

The aim of the study was to determine the effect of gamma radiation on barley (Hordeum vulgare L.) seed germination and changes of seed viability associated with aging. The seed samples of the variety 'Astor' were irradiated at the Jožef Štefan Institute, in the Reactor Centre at Podgorica near Ljubljana, in 2006. The samples were irradiated with three different doses: 0.1, 0.2 and 0.4 kGy. After the irradiation, the seeds were stored in a refrigerator at 4 °C. The percentage of seed germination was tested each year after irradiation until 2014, except in the second and the third year. The experiments were based on the Latin square design with 4 replications of each treatment, and were conducted in a greenhouse under controlled temperature at 20 °C. In all years, the samples irradiated with the highest dose (0.4 kGy) exhibited a significantly lower percentage of germination. The germination rate of the samples irradiated with 0.2 and 0.4 kGy decreased significantly with aging, when compared to the control and the samples irradiated with 0.1 kGy. In all years of testing, the percentage of germination of seeds irradiated with 0.1 kGy did not differ from the control, and in the fifth year after irradiation, it was even significantly higher than the control.

“…A positive effect of the laser light exposure on the content of sugars in sugar beet roots was observed in the studies conducted by, e.g. -Inyushin et al (1981), Koper (1994) and by Sacała et al (2012). Dobrowolski et al (1992) demonstrated an effect of laser light on the content of certain microelements in tomato fruits.…”

Due to the common trend towards limitation of excessive use of chemicals in agriculture, there is a growth of interest in methods of seed quality improvement that would be safe for the environment. These include methods based on the effect of various physical factors, such as laser light, magnetic field, seed treatment with magnetized water, electric field. The work provides detailed information on the impact of seed stimulation of these factors on germination, growth, development and yielding of horticultural plants. Summarizing the results of the study, it can be concluded that the application of physical factors in appropriate doses can be an effective way to enhance many plant parameters that increase their productivity. The beneficial effects of seed stimulation are mainly related to the first stages of plant life, i.e. – germination, emergence and growth of seedlings. In many cases, the enhancement of these features is also the result of the increase of plant yields. The increase of yield is even several dozen percent. The results of the study encourage the implementation of these physical methods of seed quality improvement into agricultural and horticultural practice.

“…On the other hand, excess of energy absorbed by seeds, may accelerate plant metabolism and finally result in its growth improvement. One of the positive effects of laser biostimulation is the increased concentration of photosynthetic pigments in leaves (Sacata et al, 2012). Investigated the effects of pre-sowing seed treatments with gamma ray on the germination, emergence and seedling establishment of wheat had positive results (Hegazi and Hamideldin, 2010).…”

The aim is to study the effects of physical seed priming on germination and yield of lemon balm. Laboratory and pots experiments were conducted as factorial based on completely randomized design. The treatments are magnetic field with 75 mT for 10 and 15 min durations; laser light with 2 mw.cm -2 for 20 min; ultrasonic wave with physiotrapy device for 20 min; cs-gamma ray for one hour in lead cell, and control that were applied on two landraces of lemon balm ('Karaj' , 'Esfahan'). Then in laboratory with use of special paper and pure water the seeds were cultured in petri-dishes and were putt in germinator with 19°C temperature for 8 days and were counted daily. Some parts of primed seeds were stored in normal condition for 6 months and were cultured in laboratory condition. All the primed seeds were farmed in pots. Three months later the plants were harvested in first blooming level and dry weight and essential oil percentage were measured. Results showed that the influence of various treatments on germination percentage and germination rate were significant. Magnetic field treatment (15 min) showed the highest positive effect on percentage (86%), and rate. The length and weight of seedling in magnetic field treatment were the highest in comparison with other ones. Considering physiological characteristics, the higher Leaf Area Ratio and Leaf Area Index were seen in magnetic field. Effect of different treatments on plant height, biomass dry weight and essential oil concentration was significant.
