The film was exposed to radiation from the sample and then developed to obtain a microradiograph. When the microradiograph of the grain was examined under a microscope, [sup.137]Cs was found to have accumulated around the plumule and radicle, suggesting that [sup.137]Cs was not incorporated into the newly developing tissue itself but instead accumulated in the surrounding meristem tissue.
The full set of microradiograph and histology figures appears in the supplementary material (in Supplementary Material available online at https://doi.org/10.1155/2017/7910432).
