Abstract: Dried seeds of maize were carried on board recoverable satellite under space conditions of 176km to 354km from sea level.Various ultrastructure changes of maize cells of young leaves were observed,including plasmolysis,expansion of vacuoles and cell walls,proliferation of plasmadesmi,variations of grana disc and stroma thylakoids,breath of nuclear membranes and chloroplast,inscrease in number and enlargement of endoplasm reti culums and variations of other endomembranes.
