  Comparative structural, functional and biochemical investigations of first true leaves of 7-day Arabidopsis thaliana (L.) Heynh. seedlings under conditions of slow horizontal clinorotation (2 prm) and station control are performed. Formation of central vacuole is fasted by clinorotation, partial volume of chloroplasts in a cell and summary length of photomembranes are increased under clinorotation. Their photochemical and change reactions through out more intensively. The results of our calculations indicate that stress stimulation of seedling growth takes place under clinorotation conditions.
