lignification

It is still an open question whether the cellulose constituents of the lignocelluloses are progressively condensed -- with progress of 'lignification' -- to the unsaturated or lignone groups.

Then the root tips get tucked into the ground, a process that triggers so-called lignification in which the roots start to harden and grow thicker and thicker.

· Bamboos differ from grasses in the long life-span of the culms (hollow stalk), their branching and lignification (development of woody tissues).

The plant develops as a series of shoots, bulbs and stem tubers connected by brown wiry rhizomes which are strengthened by lignification of the inner cortex.

Studies on the lignin and cellulose contents of fedder crops and effect of lignification of cellulose digestion.

A number of experiments conducted with grafting of the herbaceous growth of trees in advance of lignification has resulted wholly in failure with both soft wood and hard wood trees.

These grafts sometimes remained quite green and promising for a period of a month but lignification progressed in the stock without extending to the scion.

Speculation would introduce the idea that lignification relates to a hormone influence proceeding from the leaves of a tree and that the leafless scion does not send forth hormones for stimulating the cells of the scion to the point of furnishing enzymes for wood building.

It will be thus seen that there are no changes of any essential kind in the chemical composition of the bast fibre throughout the life-history of the plant, confirming the conclusion that the 'incrustation' view of lignification is consistent only with the structural features of the changes, and so far as it has assumed the gradual overlaying of a cellulose fibre with the lignone substance it is not in accordance with the facts.

He saw their proportions, the distances between the single parts, the degree of lignification, the intensity of colour, etc., varying with the varied conditions, yet never concealing the identity of the species.
