Design of Plant Incubator under Microgravity Environment

For the research of the plant's biological effect under microgravity condition and the requirement of microgravity signal transduction, the seeding of Arabidopsis thaliana were cultured under microgravity condition. The plant incubator is mainly composed of cultivate unit, light unit, fixed unit and observational unit. The cultivate unit contains Unit1 and Unit2; the fixed unit contains infusion pump, check value and fluid reservoir; and the observation unit is mainly composed of a visible light camera and multispectral camera. Digital images of plant samples were collected, stored and transmitted in real time during the process of space experiments, and the biological samples were fixed and stored during the culture process. The biological effects of plants under microgravity condition will be studied after the retrieved capsule returning to the ground.
