F.  aThe physiology of growth subterranean cloverbI seedling growth and the patern of growth at the shoot apex.  c1970  aThe shoot of Trifolium subterraneum L. is spirodistichous, with a divergence agle of 160graus and a phyllotaxis index of 2. The vegetative plant is defined quantitatively in terms of lengths of successive leaves, leaf areas, and dry weights of the leaves and all major plant parts for a 29-day growth period. The selected environment gave very high values of net assimilation rate (3.0 mg cm-2 day-1 for early growth). The properties of the shoot apical system are further defined in terms of volumes of meristematic and very young parts. The picture is extended by linking it with fresh weight data for the leaves.1 aBOUMA, D.  tAust. J. Bot.gv.18, p.127-148, 1970.
