Description T-8353
Seeds are fundamental to agriculture and natural ecosystem. Fundamental knowledge about
mechanism underlying seed development, germinability, dormancy and storability is required to
improve seed performance. Since the success of crop production relies heavily on high quality
planting material, the Government of India enacted Seed Act in 1966, so that all seed sold should
conform to the minimum standards of physical and genetic purity, germination, moisture content
and seed health. These seed quality parameters, known as Indian Minimum Seed Certification
Standards, have been notified for more than 95 crops viz. cereals, pulses, vegetables etc. and
compiled in “Indian Minimum Seed Certification Standards” by N. S. Tunwar and S.V. Singh,
published by the Central Seed Certification Board, Ministry of Agriculture and Cooperation,
Govt. of India, New Delhi in 1988. However, no such standards of seed quality parameters are
available for medicinal crops which have high commercial value. Seed testing protocols are also
not available, which is a pre-requisite for testing the seeds and also for recommending minimum
limits of germination (Parihar, 2006; Parihar and Kumar, 2006). Seed testing protocols are
regularly updated by ISTA (International Seed Testing Association) on the basis of research
work done globally through publication of research papers. The latest International Rules for
Seed Testing (ISTA 2009) contain seed testing protocols for a large number of plant species
cultivated all over the world and it forms the basic reference book for all kinds of seed testing
activities and also for the international seed trade. Keeping in view the above, the present
research work was undertaken on two medicinal crops senna and muskdana.
