Seed Germination and Their Photon Emission Profile Following Exposure to a Rotating Magnetic Field

A multitude of experiments have applied magnetic fields to plants or seeds and found a variety of different and sometimes contradicting results. A magnetic field generating device called the Chrysalis resonator has been shown to influence the brain activity of human participants, the photon emissions from bacteria, mammalian cell cultures and water. In this experiment sunflower seeds (Helianthus annus) were allowed to begin germination and then exposed to either the field generated by the Chrysalis resonator or a sham condition. Their growth and photon emissions were taken over the next 5 days. It was found that the seeds showed less germination 48 hours after exposure and significantly higher photon emissions when 3 seeds were measured together in a dish, but not if 2 seeds or 1 seed were measured. There were no significant differences in the photon measurements from the water the seeds were germinating in. These results may indicate that the seeds became more sensitive to the presence of neighbouring seeds. The photon emissions results were also significantly impacted by external weather conditions.


Introduction
The characteristics of magnetic field treatments previously used to treat plants are highly variable, and so are the results [1] [2]. Some consistent findings seem to be reduced growth when high frequency (GHz) magnetic fields such as from cell phones or Gunn generators (produce fields in the microwave frequencies)

Seed Germination Preparation
Sunflowers (Helianthus annus) were obtained from the gardening section of a local department store (subtype, Russian mammoth). For each trial, 108 seeds were split between two solutions of 25 mL of a 5% bleach solution, submerged for 5 minutes and then washed with tap water. The seeds were put into 100 mm petri dishes with 10 mL of President's Choice spring water for germination, with 18 seeds per dish. In each trial there were three 100 mm dishes in each condition. Three trials were completed of this experiment.

Rotating Magnetic Field Device
The magnetic field device used in this experiment is known as the Chrysalis resonator. It is one model of many that produces a magnetic field around 110 Hz.
In this model the exact peak frequency of the magnetic field was 113 Hz. The magnetic field has a strength of approximately 0.75 Gauss, or 75 μT. A description of a similar model of this device has been previously published [31] and can also be found in the patent (Canadian Patent No. CA 2631215). Briefly, the magnetic field is generated by cylinders that rotate within the device at about 3000 -4000 rotations per minute when the device is on. The cylinders inside the device are arranged in a circle and contain puck magnets, these rotating puck magnets are responsible for generating the magnetic field.

Procedure
After the seeds were placed into their dishes, they were placed directly on the Chrysalis resonator for 1 hour to either be exposed to the field or to the sham condition (field OFF but with the fan running). Both conditions were complete on the same day with an hour between exposures. When not being exposed and during germination, the seeds were placed on flat surfaces in the dark. Starting 24 hours after exposure, daily measurements were taken for five days to determine if each seed had begun to germinate and to measure the length of the root/stem that had emerged from the shell. Statistical analysis of the length measurements were complete only on the seeds that had begun germination.
After taking growth measurements, photon measurements were taken on a photomultiplier tube (PMT). The PMT was model DM0089C, which is most sensitive to photons of wavelengths between 280 to 630 nm. For preparation, 6 seeds were picked from each condition that were within a range of seedling length measurements that had been taken that day (Table 1). These were then put into three 35 mm dishes; in the first dish there was one seed, in the second dish there were two seeds and in the third dish there were three seeds. Each of these dishes contained 0.5 mL of fresh spring water, this was to reduce the amount of stress that may have been occurring by measuring these seeds. Additionally, there were 35 mm dishes measured that contained 1 mL of spring water from the dishes of germinating seeds. The PMT was housed in a black-painted wooden box that was covered in black towels. The seed dishes were placed on top of the PMT aperture. Samples were measured three times for one minute intervals at a sampling rate of 50 Hz. For statistical analysis, the average of the second and third recording was used. The first recording was not used to reduce the effect of light pollution. An example of a recording can be seen in Figure 1, from this the mean of all the points was computed as well as the standard deviation of all the points.

Germination
Seeds were germinated in 100 mm petri dishes, with 18 seeds in one dish. The percent number of seeds in each dish that germinated were calculated for each day for both the magnetic field exposure and sham condition. The average was taken of the three dishes in each condition. There was a significant interaction between day of measure and the field condition [F(4, 16) = 4.51, p = 0.013; pη 2 = 0.53; Figure 2]. There was a significant decrease in the proportion of seeds which germinated for the magnetic field condition compared to the sham condition. Paired t-tests for each condition showed the interaction comes from difference in slope between day 1 and day 2 for the two conditions ( Figure 2), evident in the disparity between the t-statistics (Table 2). This indicates that the effect on germination rate wasn't evident until the day 2 measurement, which was taken 48 hours after exposure.
Length of seedling was then measured for the seeds that had germinated. There was no significant difference between the field exposed of sham exposed seedlings [F(4, 16) = 0.45, p = 0.770; Figure 3].

Photon-Seed
Initial results indicated no significant effects, however there was a large variability between the average number of photons between the different replicate of experiments [F(2, 17) = 15.2, p < 0.001, Ω 2 = 19.3%; Figure 4], as well as large differences in the standard deviation of the number of photons [F(2, 17) = 27.0, p < 0.001, Ω 2 = 24.8%; Figure 4]. In both variables, Tukey's post hoc test determined that the second replicate was significantly higher than the first and third replicate (p < 0.05).  .

Error bars represent SEM. Figure 3. The length of seedling over the 5 days of germination in the dark. Seeds begun germination at Day 0 and were subsequently exposed to one of the conditions. Error bars represent SEM.   Due to this large variability between replicates, two statistical methods were used for further analysis. The first was entering weather variables into the dataset, to see if controlling for any of these removed the variability. Second, within-subjects z-scores for each replicate were used as well to confirm any results found with the weather variables.
Weather variables included in the dataset were the daily and hourly average of temperature, relative humidity and AP index. Also included were the hour of day (in Eastern Standard Time) the measurements were taken and the day of year the replicate began. Using a series of multivariate analysis of covariances (MANCOVAs) it was determined that most of the significant covariates were from the between subjects analysis (between the three replications) and not the within subjects analyses (within each single replication) ( Table 3). Temperature and humidity explained the most variance when using the values for the hour of photon measurement, whereas the AP index explained the most variance when using the daily average values (Table 3). A regression analysis was used with all of the weather variables and the mean number of photons. The only variable that entered as a predictor was the daily average AP index [F(1, 17) = 32.4, p ≤ 0.001, r 2 = 0.648; Table 4].     Figure 6]. Paired t-tests showed that none of the groups were significantly different in the Sham condition (p > 0.05) but that in the Field + vibrations condition, the 3seed was group was significantly greater than the 2 seed and the 1 seed group (p < 0.05). These are the same differences found between groups as was found in the residual analysis for the standard deviation of photon recordings.

Photon-Water
There were no differences between the sham and field condition in the photon emissions measured from the water the seeds had been germinating in (p >

Discussion
Exposure to the dynamic field of the Chrysalis resonator (and its vibrations) caused approximately a 15% decrease in the number of seeds that germinated.
This appeared in the measurements 48 hours after exposure, while there was no difference in germination 24 hours after exposure. Delayed effects of magnetic field exposure on germination have been previously reported [14] [15]. In a recent study involving seed germination and magnetic fields [15], authors found greatest differences between the magnetic field and sham groups at 96 hours after exposure. Decreased germination is an effect previously found with high frequency man-made fields [3] or environments that reduced the background intensity of the Earth's static magnetic field [7]. Is it possible that these two broad categories of magnetic field treatments are reducing a developing seeds coherence or connection with the Earth's magnetic field? The phenomenon of this type of coherence has already been demonstrated in humans [32] [33] [34], where  Figure 6. Z-scores of the standard deviation of recording of photon emissions per second per cm 2 (assumed diameter of 2.5 cm for PMT aperture) between the number of seeds measured each replicate. Error bars represent SEM. The interaction in photon emissions with number of seeds was evaluated with two different statistical techniques. When using residuals that had controlled for weather variables, the interaction was significant both in the mean photons and standard deviation of photon emissions over the measurement period. However, when using the within subject z-score methods, only the standard deviation interaction remained significant. This indicates that this variable demonstrated the greatest change from exposure to the dynamic condition of the Chrysalis resonator and that the changes in SD would be seen to a lesser extent in the mean values.
Photon communication in biological organisms has been demonstrated many times [17] [18]. For example, it has been found that germinating radish seeds that had been exposed to gamma irradiation could influence the germination rate of other radish seeds that had never been exposed (Kuzin & Surbenova, 1995 in [35]). Indicating a potential for seed to seed communication through photon emission; when the seed germination rate was altered, these seeds may have been influenced by nearby seeds' through biophoton emission. Biophoton signalling has been previously implicated in the start of germination [30], in this experiment, the resonator may have altered the biophoton signalling of the seeds and as a result interfered with their germination.
In the present experiment, we found altered biophoton emission, but only when three germinating seeds were measured together, and not when one or two seeds were measured. There are several phenomena that could explain this result. The first is signal to noise ratio, where all of the seeds had altered biophoton emission, but three seeds were needed for the PMT to be able to detect the difference between conditions. Another explanation for the results is that the increased photon emissions of the three seeds measured together was the result of a stress reaction in the seeds due to overcrowding. It has been previously demonstrated that changes in population density of biological organisms can alter their biophoton emission [16] and also influence the growth of organisms nearby [18] [23]. This could imply that the resonator induced the germinating seeds to be hyper sensitive to the presence of other seeds nearby. This may also explain the decrease in germination that was found, in that it was a response to increased population density, which could also explain why the decrease in germination was found 48 hours after the beginning of germination and not 24 hours after. There is an increased likelihood that the plants would be able to sense the presence of surrounding seeds at that time, either by their individual biophoton emission, physical contact or seed leachates.

Conclusion
This experiment demonstrated that the Chrysalis resonator can affect the germination of sunflower seeds as well as their biophoton emissions. Further re-
