“…a considerable increase of treatment effect when working with stressed seeds (Brizzi et al , 2011. This behavior was confirmed in a recent review regarding the use of homeopathic preparations in experimental studies with abiotically stressed plants (Jäger et al 2011), whereas in healthy plant tests the effects were less pronounced ). The first general conclusion we can make on the germination results reported here is that the As 45× treatment induced a marked stimulating effect, in terms of an overall reduction in the number of non-germinated seeds (−26.6%).…”

This study concerns the biological effects and physico-chemical variations of extremely diluted solutions (EDS) as a function of aging-time. The biological efficacy of As 2 O 3 at the 45th decimal dilution/succussion (As 45×) was tested in a wheat germination model. Ten trials were carried out from 0 to 12 months after treatment preparation, using wheat seeds (Triticum aestivum L.) of the Pandas variety. Seeds were pre-treated by poisoning with 0.1% As 2 O 3 solution to reduce germination, to allow a better evaluation of treatment effects. The outcome variable was the number of non-germinated seeds after 96 h. The As 45× treatment aged for less than three months did not show a significant effect on wheat germination, whereas when aged for longer (3-12 months) the effect became significant. Concerning the physico-chemical characteristics, specific conductivity of As 45× aged from 0 to 12 months was measured, using nine samples for each date. The results showed a clear increasing time trend of specific conductivity, more evident when considering the last three measurements, which correspond to more than six months of aging. The physico-chemical behavior of EDS strongly supports the significant biological effects observed in a wheat model.

“…Since several experiments demonstrated that diseased plants normally have a more marked reaction to treatments at low or high dilution level than healthy ones [3], we decided to use an isopathic approach, as performed in other plant model systems [8,17]. According to isopathy, the same substance causing the disease can be used in low doses or high dilutions to treat the disease itself [18]: in our experimentation preliminary stressing of pollen grains with sub-lethal doses of arsenic trioxide was carried out in order to reduce germination rate, followed by treatments with the same substance at low and ultra-high dilutions.…”

Introduction: This study deals with the effects of extremely low doses or high dilutions of pharmacological compounds on in vitro pollen germination of kiwifruit (Actinidia deliciosa). Material and Methods: The biological efficacy of As₂O₃ at the 5th and 45th decimal dilution/succussion level (As 5x and As 45x) was tested on pollen previously stressed with As₂O₃ 150 or 200 μM. The outcome variable was the pollen germination rate, as detected blind after 3 h 30 min by an Axioplan microscope. Results: A directionally consistent recovery of germination percentage was observed in both As 5x and As 45x after stressing with As₂O₃ 150 μM. When pollen was stressed with As₂O₃ 200 μM only as 45x induced a general and significant germination increase. Conclusions: Our results suggest that both treatments might partially remove the inhibitory effect caused by the stressor. Similar effects were observed on the same model using weak extremely low frequency magnetic fields (ELF-MFs) mediated through water. Although preliminary, the findings seem to indicate the in vitro pollen performance as adequate to study the effects of physicochemical subthreshold stimuli (extremely low doses or high dilutions of pharmacological compounds, weak ELF-MFs), mediated through water.
