The guanidine-dependent variant of poliovirus type I was shown to survive in soil and on tomato plants for 60 and 25 days, and in the roots, stems, leaves for 15, 20, and 8 days, respectively. Extrapolation of the significance of these results indicates that the decline of concentration of the indicator virus in the soil and on the vegetables and its increase and decline in the root system, stems, leaves, and in tomatoes is of exponential nature.
I型脊髓灰质炎病毒的胍依赖性变种在土壤和番茄植株上分别存活60天和25天，在根、茎、叶中分别存活15天、20天和8天。对这些结果重要性的推断表明，指示病毒在土壤、蔬菜上的浓度下降以及在根系、茎、叶和番茄中的增减呈指数性质。
