C. follicles. is a complex process that involves the differentiation of secondary phloic fibres (SPF) from the cambium followed by lignification of the fibre wall. Topics similar to or like Bast fibre. Bast fibers are obtained from the outer layer of the plant fiber and in the form of fibrous bundles and comprise one-third of the weight. INTRODUCTION. is a complex process that involves the differentiation of secondary phloic fibres (SPF) from … The bast fibers can be used to make textiles that are 100% hemp, but they are commonly blended with other fibers, such as flax, cotton or silk, as well as virgin and recycled polyester, to make woven fabrics for apparel and furnishings. Our study shows that mutation could specifically impair the cambial activity by rendering those initials that differentiate the SPF and secondary xylem nonfunctional. Bast fibre (also called phloem fibre or skin fibre) is plant fibre collected from the phloem (the "inner bark", sometimes called "skin") or bast surrounding the stem of certain dicotyledonous plants.It supports the conductive cells of the phloem and provides strength to the stem.
