Stages of silk production 

Sericulture. This is the term used to describe the process of gathering the silkworms and harvesting the cocoon to collect the materials. ... 

Thread extraction. ... 

Dyeing. ... 

Spinning. ... 

Weaving. ... 

Finishing.

Process of silk production

The process of silk production is known as sericulture. ... Extracting raw silk starts by cultivating the silkworms on mulberry leaves. Once the worms start pupating in their cocoons, these are dissolved in boiling water in order for individual long fibres to be extracted and fed into the spinning reel



Major diseass in sericulture

Major silkworm diseases are viral such as nuclear polyhedrosis (Bombyx mori nucleopolyhedrovirus; BmNPV), cytoplasmic polyhedrosis (Bombyx mori cytoplasmic polyhedrovirus; BmCPV), infectious flacherie (Bombyx mori infectious flacherie virus; BmIFV), densonucleosis (Bombyx mori densovirus; BmDNV); bacterial such as


Importance of sericulture

GRAFT OR BUD UNION Author:- S.Hemanth

Physiology of graft (or) bud union formation   Article by:- S.Hemanth A. Characteristics of a functional graft union  Mechanical strength  Initially some sticking together of scion and stock is achieved by intercellular adhesion at first and intermingling of callus subsequently, but ultimately it is the interlocking of xylem fibers (wood) that results in a strong, permanent graft union.  Translocation   The structural integrity of the graft union not only holds the grafted plant together, but it is the reestablishment of anatomical and functional continuity between xylem and phloem that allows for translocation of water and minerals by the xylem, and conduction of carbohydrates and other organics by the phloem.    B. Sequence of graft union formation  Necrotic plate  The necrotic plate is a layer of desiccated, crushed cell walls at the cut surface of both stock and scion. Suberin (a waxy material) and pectin...
