Abstract
High-temperature accelerated ageing (at 30deg C and 100% RH) of sugar beet (Beta vulgaris L. cv. Loke) seeds resulted in radual loss of dry weight, viability and vigour of seeds, and lowering of mitochondrial respiratory rate and activities of cytochrome c oxidase and malate dehydrogenase in mitochondria. Protein composition in mitochondria showed marked changes with ageing of seeds; low-molecular weight heat shock protein (LMW HSP) 22 increased from 0 d to 30 d of ageing, and then decreased from 30 d to 90 d of ageing. It was found that changes in mitochondria activity and LMW HSP 22 content were closely correlated with seed vigour during accelerated ageing of sugar beet seeds.
