A study of carbohydrate metabolism in the roots of pea and maize showed that the differing ability of these spp. to grow at low temp. was associated with the maintenance of adequate sugar supplies to the root tip. In maize, reducing the ambient temp. to 2 deg C caused a sharp and continuing fall in the soluble sugar content of the growing tip, while in pea there was only a temporary reduction in sugar content lasting <24 h.
