This tissue is usually one to several layers thick, with cells walls of uneven thickness due to uneven lignification.
2.
In ruminant nutrition, depending on the extent of lignification of the cell wall, pectin is up to 90 % digestible by bacterial enzymes.
3.
This white crystalline solid is a metabolite in conifers, serving as an intermediate in cell wall lignification, as well as having other biological roles.
4.
"' Hyperhydricity "'( previously known as vitrification ) is a hydration, low lignification, impaired stomatal function and reduced mechanical strength of tissue culture-generated plants.
5.
The references consulted do not agree as to whether the fruit is a nucule or achene, the difference between the two ultimately depends on the size of the pericarp and the extent of its lignification.
6.
In apparent opposition to the ascetic ideal, science has succeeded merely in demolishing the ideal's " outworks, sheathing, play of masks, [ . . . ] its temporary solidification, lignification, dogmatization " ( ?5 ).
7.
They will observe the lignification of the stems as they turn from being flexible and green to hard, woody and brown ( for many varieties but not all ) indicating that vine has completed its work in developing its " offspring " grape clusters and has started to store carbohydrates and resources for its next growing season.
