" As for germination rate, the inhibitory effect was not statistically significant for duration of exposure up to 30 minutes, a distance from the cell phone as close as 5 cm and with exposure to two different cell phone brands. On the other hand, significant decline in number of germinated seeds compared to control group was observed when cell phone was used in the (non-talking) status than in the (talking) status (p = .006). A logistic regression was performed to ascertain the effects of different variables on the likelihood of germination. According to the model, seeds exposed to cell phone brand B were .8 times less likely to germinate than those exposed to cell phone brand A. In addition, seeds exposed to cell phone in the non-talking status were .714 times less likely to germinate than those exposed to a talking cell phone. Concerning the effect on embryonic stem length, distance from cell phone, cell phone brand, and cell phone status (talking/non-talking) had statistically significant inhibitory effects on embryonic stem length of exposed seeds as determined by one-way ANOVA (p = .001, .000 and .007 respectively). A linear regression was performed to ascertain the effects of different variables. According to the model, distance from cell phone and cell phone brand negatively predicted embryonic stem length (B= -.218 and -.636 respectively). Cell phone brand was stronger predictor than distance from cell phone (p = .000 and .007 respectively)."
