棉纤维由棉胚珠表皮细胞分化生长而成,是研究细胞分化、细胞伸长等机理的良好材料。为了更好地研究它的分化和发育,人们建立了多种实验系统:离体胚珠培养系统、胚珠来源的单细胞悬浮培养系统、胚珠愈伤组织细胞来源的细胞悬浮培养系统,并对这些实验系统的特点对纤维细胞分化和生长,如培养基的配方、激素配比、pH值、抑制剂或促进剂的影响等进行了较为系统的研究。发现棉纤维的发育 Cotton fiber from cotton ovule epidermal cells differentiated from growth, is to study cell differentiation, cell elongation and other mechanisms of good material. In order to better study its differentiation and development, a variety of experimental systems have been established: in vitro ovule culture system, ovule-derived single cell suspension culture system, ovule callus cell-derived cell suspension culture system, and these experiments The characteristics of the system of fibroblast differentiation and growth, such as medium formula, hormone ratio, pH value, the effect of inhibitors or accelerators such as a more systematic study. Found that the development of cotton fiber
