Space exploration is
man’s greatest means to subdue his environment and accelerate development.
spinoff of the exploration has brought relief for mankind. If man is to survive
in space, the gravitational effects on the root of indigenous plants became our
concern. The project was carried out at the laboratory of African Regional
Center for Space Science and Technology Obafemi Awolowo University, Ile-Ife.
The indigenous seed used was okra. Image J application software and Microsoft
excel was used for data analysis.  Six
readings were taking at 30 minutes interval to determine the growth rate.  The research has shown the possible growth of
plant under variation of gravitational force. There was decrease in the value
of angle of Curvature comparing its value at each 30 minutes interval for
clinostat sample and 900 turned sample.  There are increases in the length per time
with 900 turned with the largest value of 0.283cm followed by 1g
sample (0.253) and clinostat experiencing the least growth of 0.218cm.  This implies that the root of okra will grow
faster in 900 turned position (while Gravitational force is acting
on it) than micro gravity position (Clinostat sample). It was discovered that
there are differences in the growth of the root of plants because of gravity
influence. It has been practically established that the gravitational variation
influences the growth of the root of plant. Plant under weak gravitational
force (micro gravity) has stunted growth in comparison with others under full
gravitational force (earth).
