Changes in physical and physiological attributes of irrigated and rainfed groundnut seeds during storage

摘要

Changes in moisture content, germination, dry matter production of seedlings and vigour index were studied in rainfed and irrigated groundnut (Arachis hypogaea L.) during storage. Moisture content of seed increased with increase in storage period, while germination, dry matter production of seedlings and vigour index decreased with increase in storage period. The decrease in these parameters was slow in rainfed seed compared to irrigated seed. The rainfed seeds were stored upto 10 months with minimum seed certification standard of 70% germination, whereas the irrigated seed lost its viability within six months.
