Abstract: SUMMARY1. The effect of ageing on seed viability, seedling growth and cellular damage was studies in Triticale seeds (2 n=56) of various ages. Old seeds generally showed reduced viability, slow growth rate accompanied by variable amount of chromosomal damage.2. No linear relationship could be found between the period of ageing and deleterious effects but after an initial lag period effects increased in later year significantly.3. To a treatment with EMS old seeds showed greater sensitivity than the fresh ones. Positive relation was found between chromosomal aberrations and loss of viability on one hand and period of ageing and chromosomal damage on the other.4. The death of embryo causing the loss of viability is regarded to be due to production and accumulation of nuclear damage in which respiratory waste products, normal metabolites, etc. play a direct role.5. It is indicated that effects have taken place during the period of ageing and are present before the onset of germination.
