Natural Bast Fibers are strong, cellulosic fibers obtained from the phloem or outer bark of jute, kenaf, flax and hemp plants. 2.6.4 Bast Fibres. Jute fibre deteriorates quickly due to presence of [Orissa JEE 2004] A) High cellulose done clear. The two species differ in the quality of fibre they yield. Inheritance of fibre (bast) in jute (C. capsularis) is monogenic and recessive. Most bast fibers are quite strong and are widely used in the manufacture of ropes and twines, bagging materials, and heavy-duty industrial fabrics. Botanically, the fibers harvested from many of these plants are bast fibers; the fibers come from the phloem tissue of the plant. 2. Phloem (or bast) fibres are a common source of commercial fibres and are produced from several plant species, including Corchorus capsularis and C. olitorius (jute), Linus usitatissimum (flax), Boehmeria nivea (ramie) and others (Kirby, 1963).In these dicotyledonous plants, the commercial fibres are sclerenchyma cells with copious secondary wall thickening (Kundu, 1944; Fahn, … Jute is a herbaceous, little branched annual plant. We generated the bast transcriptomes of a deficient lignified phloem fibre mutant and its wild-type jute (Corchorus capsularis) using Illumina paired-end sequencing. They appear as wedge-shaped bundles of cells intermingled with parenchyma cells and other soft tissue. View Solution play_arrow; Download Complete Course. Bast fibres are long extraxylary cells which mechanically support the phloem and they are divided into xylan- and gelatinous-type, depending on the composition of their secondary cell walls. See also: The cell is defined as the fundamental, functional unit … The genus Corchorus is composed of approximately 100 species [ 2 , 3 ]. Phloem is composed of various specialized cells called sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells. Jute fibers are composed primarily of the plant materials cellulose and lignin. It is produced from flowering plants in the genus Corchorus, which is in the mallow family Malvaceae.The primary source of the fiber is Corchorus olitorius, but it is considered inferior to Corchorus capsularis. " The best fibres occur in the outer portion of the stem, interspersed with thin-walled tissues of phloem. Bast fibers are used for textiles, rope, and paper. bast fibres are also known as phloem fibre or skin fibres. B) Low cellulose done clear. It supports the conductive cells of the phloem and provides strength to the stem. The fibres consist of sclerenchyma bundles. The secondary phloic fibres, which are the derivatives of vascular cambium, are found lacking, though there is formation of secondary phloem pyramids from the cambial tissue. Commercially useful bast fibers include flax, hemp, jute, kenaf, ramie, and nettle. Fibre from C. olitorius, an upland species with long pods, is but little inferior. Extraction of Jute Fibers. Fibres are obtained from the stem of two species, i.e., C. capsularis and C. olitorius. A total of 34,163 wild-type and 29,463 mutant unigenes, with average lengths of 1442 and 1136 bp, respectively, were assembled de novo, ~77-79 % of which were functionally annotated.

Jute is an annual herbaceous dicotyledonous plant that grows to a height of 1.5–4.5 m. The stems are about 1–2 cm in diameter with few branches. A. Ramie Bast, also known as phloem fiber, is produced from the inner bark, or bast, portion of the stem of certain plants.
