“…Earlier it was suggested that all the fibres in jute including the first-formed protophloic fibres are secondary in origin from cambium, and therefore secondary phloic in nature (Kundu 1956;Kundu et al 1959). Later studies, however, unequivocally confirmed the presence of two types of fibresprimary phloic fibre (PPF) that develops from procambium in the protophloem region through cell division and modification, and secondary phloic fibre (SPF) that develops from cambium by the activity of fusiform and ray initials (Maiti and Mitra 1972;Maiti 1980;Mitra 1984;.…”

Bast fibre development in jute (Corchorus spp.) is a complex process that involves the differentiation of secondary phloic fibres (SPF) from the cambium followed by lignification of the fibre wall. We have identified a unique radiation-induced bast fibre-shy mutant of dark jute (C. olitorius L.), which is concurrently defective in the differentiation of SPF and secondary xylem (wood) but develops lignified fibre cells. It displays the most unusual phenotype with stunted growth and abnormal leaf shape, matures earlier, yields significantly less bast fibres and wood, and produces poorer quality fibres than its parental wild-type. Cambial activities in the mutant and the normal type were monitored by estimating the fibre content that entails the total number of fibre cell bundles (FCBs) in an entire transversal section. The results show that a multifold reduction of bast fibre yield in the mutant is related to development-specific loss of cambium function along the length of the stem from to top to bottom. Since lignification of the fibre wall in the mutant is not only normal but also developmentally uniform, cambium function may be unrelated to the lignification process during bast fibre development. Lignin does not influence bast fibre strength and fineness. The architecture of the mostly triangular FCB wedges, which is governed by a balanced growth between radially elongating FCBs and tangentially expanding ray cells due to development-specific activation of the fusiform and ray initials of the cambium, conditions fibre fineness. Our study shows that mutation could specifically impair the cambial activity by rendering those initials that differentiate the SPF and secondary xylem nonfunctional.

“…The ultimate cell has considered as "natural composite" since it is composed of ultrafine fibrils with oriented alpha cellulose and less ordered amorphous region that reinforcing the matrix of hemicellulose and lignin. Due to presence of uronic acid in hemicellulose, jute fiber behaves as acidic and reducing medium (Kundu 1956). …”

Over the years, technologies had used for development of various textile products to meet the consumer demands in different fields as per their end-use specifications. The market sustainability of the each new product mainly depends on the raw material as well as functionality. A functional finishing decides the end-use of the products as well as enhances the life of the products. Jute is one of the important natural cellulosic fibers and mainly used for sacking and packaging, rather than it has many advantageous properties. Similar to cotton, jute fiber has the potential to impart different functionality by different chemical finishing for its diversification. This paper reviews the functional finishing on jute textiles with special reference to softening, crease resistant, fire retardant, and hygiene for the satisfaction of the consumer's demand are reviewed.

“…Recently the genus has been reclassified within the family Sparrmanniaceae [9]. It has been reported to originate from Indo-Burma and Africa [10] and is natural inhabitant of the tropical and subtropical regions of the world. The genus Corchorus, is endowed with about 215 species, subspecies, varieties and land races (Global Biodiversity Information Facility 2008), 1 out of which only 50-60 species are important [11,12].…”

Tossa jute (Corchorus olitorius L.) is an important lingo-cellulosic bast fibre-crop. It provides biodegradable and environment friendly fibre next to cotton, in terms of usage, global consumption, production, and availability. Narrow genetic diversity of the crop is the major hurdle, which is a demand at priority for any crop improvement programme. In the current investigation 138 jute genotypes of C. olitorius were characterized with ten jute specific SSR markers. A total of 23 alleles were amplified with an average of 2.3 alleles per locus and the PIC value ranged from 0.13 to 0.76 with an average of 0.455. The un-weighted pair-group method with arithmetic average cluster analysis of the 138 jute genotypes depicted a dendrogram using DARWIN, which divided the genetic resource into three major clusters. The study indicated the utility of SSR primers for providing useful and high levels of polymorphism for individual plant genotypes even with a narrow genetic base. Based on cluster analysis the most divergent genotypes identified were OIJ 167 (from Indonesia), OIM 058 and OIM 059 (India), however based on the agronomic traits as maximum plant height, basal diameter and fibre weight they were OIJ 245, OIJ (153 and 161) and OIJ 040, respectively.
