Abstract
Seed ageing leads to decreased polyamine levels. Osmotic priming with polyethylene glycol resulted in marked invigoration of aged onion seed s, Allium cepa L. cv. Punjab Red-48. Priming-induced increases in the levels of polyamines, especially putrescine and spermidine, were relat ed to the improved seed vigor. The role of polyamines is discussed in relation to membrane protection and/or repair.
