Description

Technical Field

[0001] The invention relates to a sample box used for space exposure experiments of rice seeds and Arabidopsis seeds. Background Art

[0002] Arabidopsis and rice are commonly used model organisms in biology. In space biology research, seed samples are light in weight and small in size, have no special life support requirements, can be carried in large quantities, and can be used for basic and applied research on space biological effects and genetic variation after returning. They are commonly used test biological materials. However, in the past, when using plant seeds for space exposure at home and abroad, scientists usually carried out it according to their own feasible payload resources, especially for breeding purposes. Samples were just randomly packaged in cloth bags, etc., because the local environment of each flight could not be controlled, so these methods were not conducive to comparing the experimental results of different batches of flights. With the exposure platform of my country's space station about to be put into orbit, in order to meet the needs of experimental samples in a limited environment, unify and ensure the sample loading environment, and provide the accumulated space radiation dose for each space exposure, it is necessary to develop a standard sample box suitable for the space station exposure radiation biology device, with rice seeds and Arabidopsis seeds as test organisms.
