Ratio of GA:ABA affects early germination (vivipary). 

With high levels of ABA, seeds remain dormant.

Grasslands   Grasslands are found on every continent except Antarctica, and cover about 16 per cent of the Earth’s surface.  They develop where there is not enough precipitation to support forests, but enough to prevent deserts forming.

The rate of sedimentation is dependent upon the applied centrifugal field (cm s-2), G,

that is determined by the radial distance, r, of the particle from the axis of rotation (in cm)

and the square of the angular velocity ω, of the rotor (in radians per second):
