Abstract

On average, 50 per cent of maize pollen grains can be kept viable and almost 30 per cent remain fertile for up to a year when the water content on a fresh weight basis is reduced to about 30 per cent of the original and the pollen is stored at — 76 or — 196 °C. Over this period no significant difference was found between storage at either temperature.
