Abstract

The invention provides a method for establishing the correlation between lignin content in cotton fiber and fiber quality. The traditional Klason method was improved to measure the lignin content in cotton fiber, and then the correlation and regression equation between lignin content and fiber length, specific strength and micronaire value were established. The evaluation method of fiber quality is enriched, and it has positive significance for guiding cotton breeding and production.

Description

1. Technical field [0001] The invention belongs to the field of biochemical analysis, and relates to a fiber quality detection and analysis method, in particular to a method for establishing the correlation between lignin content and fiber quality in cotton fibers. 2. Background technology [0002] Cotton fibers are formed by ovule epidermal cells through differentiation, protrusion, elongation, secondary wall thickening and dehydration maturation before and after fertilization. Scholars at home and abroad believe that mature cotton fibers do not contain lignin that forms the cross-linked structure of the cell wall. The method proves that mature cotton fibers contain lignin that forms cell wall cross-linked structures. It is also proposed that lignin is an important component of the cotton fiber cell wall and forms a cross-linked structure with polysaccharides in the cell wall, which affects the growth, strength, morphogenesis and resistance to biotic and abiotic stress of ...
