Abstract
Lignin presents important functions for plants as resistance, conduction and defense. In additions, this compound developed support for plants to grow up against the gravity. The lignin has many positive characteristic that can influence the plant life and this has open great interest to study the lignification process in cells, and the industrial process from the forest technology industrial. Through the biotechnology techniques as calogenesis and suspension cell, different growth regulator concentration were tested. 2,4-D (2,4-dichlorophenoxiacetic acid), for example, has been considered the most important phytoregulator in the regulation of the lignification in callus and in suspension cells in the different culture medium and with several kind of plant. The lignification process, that involve different steps on lignin formation, includes the pre-corismic and phenylpropanoids ways, and has been researched in the callus and suspension cell conditions. All those tools can be viable for the study of the lignification process.
