At a greater depth, branches are few or absent, and it is supposed that the deep
roots are for securing moisture. The roots do not branch or feed much in the

has begun it will cease. Johnson defines the period of germination as lasting ...

Wheat ordinarily contains from 10 to 15 per cent of moisture. Changes in the
moisture content of the air cause corresponding variations in wheat, and
consequently in its weight. Usually such fluctuations in weight do not exceed 6
per cent, but ...
