Objectives - Investigation of the conditions for reproducibility of  
dwarf pea shoot growth stimulation through homeopathic potencies of  
gibberellic acid.
Methods - 4 batches of pea seed (Pisum sativum L. cv. Früher Zwerg;  
harvests from 1997, 1998, 1999, and 2000) were tested regarding their  
reaction to gibberellic acid 17x and 18x (compared to unsuccussed and  
succussed water (1x) as controls) in 8 independent randomized and  
blinded experiments. Pea seed was immersed for 24 h in watery  
solutions of homeopathic potencies or controls, and cultivated under  
controlled laboratory conditions. Pea shoot length was measured after  
14 days. Two systematic negative control experiments assessed the  
stability of the experimental set-up.
Results - The systematic negative control experiments yielded no  
significant effects and confirmed the stability of the experimental  
set-up. 2 out of 4 seed batches reacted to the homeopathic treatment  
(p < 0.05). Seed batch 1997 showed a reproducible reaction to  
gibberellic acid 17x (shoot length stimulation of +11.2%, p = 0.007),  
and seed batch 1998 showed a significant varying response (increase/ 
decrease). Seed batch 1997 differed from the other 3 batches by an  
increased glucose and fructose content, and reduced 1000 kernel  
weight. Meta-analysis with data of earlier experiments is in  
accordance with the results of the present experimental series.
Conclusions - We identified ‘seed quality’ as a possible trigger  
factor for successful reproducibility in homeopathic basic research.  
Premature harvesting as a possible key factor for responsiveness of  
dwarf peas to homeopathic potencies of gibberellic acid is our current  
working hypothesis to be tested in future experiments.
