Utilization of spaceflight technology on medicinal plant study

Abstract

Utilization of spaceflight technology will benefit the modernization of Traditional Chinese Medicine study. Many countries, such as USA or Russia, have conducted extensive experimental research with plants in the regenerative life-support system in space stations as well as the research on breeding or chromosomal aberration after spaceflight. The space botany is still in its preliminary stage in our country. Research has mainly been focused on breeding under space-environment. In addition, many experiments have been conducted with the spaceflown plants to investigate the growth, development, biochemical and physiological changes, as well as the inheritance and variation. Little has been done with regard to the facility development to contain the spaceflying seeds and no research has been reported on plant growth in spacecrafts. Medicinal plant study has certain characteristics and advantages in our country where small biological vessels are developed for the spaceflown seeds, which are then distinguished to microgravity group and radiation exposed group with analytical instrument. However, research has been carried out in medicinal plant breeding or inheritance. In future research, more effort should be directed to the study of medicinal plants as an important link of a future biological life support system as well as to the health care of astronauts by.
