Plant proteins such as those from soybean are valuable sources of essential amino acids, but they lack the consistency and texture of meat because of their fibrous character.

Rapid determination model of the methoxyl group content in plant fibrous material was established by the integration of near-infrared spectroscopy and partial least squares (PLS).

The factors affecting fibrous roots size besides the planting vegetation, it has signal positive correlation to thickness of soil, thick soil is good to the growth and development of plant roots.
