Results and Prospects of Studying the Gravitationally Sensitive Systems of Plants under Conditions of Space Flight

Based on systematic studies of the impact of space flight factors on higher plants, carried out for many years both aboard orbital research stations and in the ground laboratories, we have formulated the means of solving the problem of the interaction of mankind with the plant life. The principal feasibility of the growth and development of higher plants (arabidopsis, peas, and wheat) under conditions of space flight is established, including the generative stage (arabidopsis). It is proved that the factors of space flight destabilize the macro- and microstructures of higher plants and their cellular organelles, which is an unambiguous response of cells to the changing conditions of their existence.
