Abstract
Trifolium repens has two types of root, one derived from the seed and the adventitious roots derived from the stolon nodes. It has been suggested that these two systems have different potentials for supporting growth. This paper presents a comparison of plants grown on single seedling or adventitious roots and demonstrates that although the shoot: root ratios for the two types differ this may be explained by differing shoot morphologies. Comparison of the lamina: root ratios for the two types of plant produced no statistically significant differences and it is proposed that the two types of root system do not differ in their relationship with leaf growth. A mechanism for large diameter ‘tap’ root formation is suggested.
