“…With further growth of the shoot lateral buds are initiated in the axils of the leaves, but in many species only develop very slowly (Williams, Sharman & Langer, 1975). However with time this main shoot dominance is lost and the laterals (tillers) commence to grow rapidly, firstly as parasites for carbon and mineral nutrients from the main shoot and subsequently as independent units.…”

Summary This review reports on the processes associated with carbon transfer and metabolism in leaves and growing organs and the role of long‐distance transport and vascular links in the regulation of carbon partitioning in plants. Partitioning is clearly influenced by both the supply and demand for photosynthate and is moderated by vascular connections and the storage capacity of the leaves and pathway tissues. However there appears to be little more than circumstantial evidence either that short distance transfer of carbon within either the source or the sink, or that long‐distance transport in the phloem, are limiting photosynthesis or growth directly. Although individual biochemical and physiological processes relating to photosynthesis and growth may be well understood, the factors primarily responsible for the control of carbon partitioning in plants have not been clearly identified. There is a need for a greater understanding of organ initiation and development (source and sink formation and potential size), the clear identification of whether growth is sink or source limited (including possible sink‐controlled photosynthesis) and a detailed assessment of the role of storage in buffering developmental and environmental changes in sink and source activity. Also more information is needed on the role of hormonal and nutritional factors in regulating source and sink activity (organ interactions not directly associated with carbon transfer).

“…In the cereals (Evans & Wardlaw, 1976;Wardlaw, 1987), as in other species (Brouwer, 1983), there is a short period following germination when the root is the major sink for seed reserves, but this dominance is lost as the shoot is exposed to light and the leaves become the major source of carbon through photosynthesis. With further growth of the shoot lateral buds are initiated in the axils of the leaves, but in many species only develop very slowly (Williams, Sharman & Langer, 1975). However with time this main shoot dominance is lost and the laterals (tillers) commence to grow rapidly, firstly as parasites for carbon and mineral nutrients from the main shoot and subsequently as independent units.…”
