Background: Accelerated ageing causes seeds to deteriorate that affect the seed quality of groundnut seeds. Seed deterioration will cause metabolic and chemical changes viz., lipid peroxidation autoxidation, leading loss membrane integrity enzyme activities. These are associated with reduced germination vigour. Methods: The cv. VRI 8 was subjected for accelerated at 40oC 100% RH upto 11 days ev...

Application temperatures and exposure environments are among the causes of premature antioxidant loss in polymer geomembranes. Therefore, over long term, degradation takes place which is reflected geomembrane properties. In this work, accelerated thermal ageing polyethylene was carried out a climatic chamber at 70℃ with 21% oxygen. The evolution tensile properties, puncture resistance, shore D ...
