Viability and vigour of ageing winter wheat grains

The viability and vigour of ageing winter wheat caryopses of the cvs. Grana and Jana were tested. Viability was determined on the basis of germination capacity and rate, and vigour on the basis of the over-all activity of hydrogenases in the sprouts, exudate conductometry, analysis of sprout growth,...

description The viability and vigour of ageing winter wheat caryopses of the cvs. Grana and Jana were tested. Viability was determined on the basis of germination capacity and rate, and vigour on the basis of the over-all activity of hydrogenases in the sprouts, exudate conductometry, analysis of sprout growth, oxygen uptake and mitochondrial protein content in the sprouts. What is called energy (or rate) of germination and over-all dehydrogenase activity in embryos and sprouts and the electroconductivity of exudates were found to be very good measures of the vigour of ageing caryopses. The latter two indices of vigour should be determined at a strictly defined moment of swelling and germination. Good measures of caryopse vigour are also respiration during swelling and at the beginning of germination and mitochondrial protein content in the sprouts or seedlings. There is a high correlation between the vigour of ageing grain and its bioenergetic indices.
