Results and prospects of studying the gravitationally sensitive systems ofplants 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 a nd in the ground laboratories, we have formulated the means of solving the problem of the interaction of mankind with the plant life. The principal fe asibility 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 fli ght destabilize the macro-and microstructures of higher plants and their ce llular organelles, which is an unambiguous response of cells to the changin g conditions of their existence.
