Seed Vigour and Invigoration

Abstract Seed vigour is an important aspect of seed quality. It a quantitative trait which responsible for overall performance in terms rate and uniformity germination, seedling growth, emergence ability under unfavourable environments post storage performance. controlled by genetic factors, initial quality, production environments, harvesting conditions. tests provide more sensitive index per se than the germination test. Efforts have been focused on developing novel or improving existing methods estimation different crops. The are tools routinely used in-house quality control programs, especially field vegetable Some treatments can improve vigour, although treatment effects evident sub-optimum optimum growing This chapter deals with aspects its plant growth discusses physiological biochemical parameters to understand underlying mechanisms.
