Abstract

The aim of this work is the statement if an initial subjecting corn seeds to the magnetic field stimulation influences on differences in a distribution structure of modulus of longitudinal elasticity of stacks of corn sprouted from this seeds. Often applied in ecological problems Gini coefficient was used to a compare the modulus of elasticity. The usage of confidence intervals was proposed to determine the significance differences of modulus of elasticity to state about influence of magnetic field stimulation to corn seeds. Confidence intervals were constructed by the bootstrap method.
