Orchestrating organs? Roots and stems not always in harmony


Figure 1
Roots are often described as the forgotten parts of a plant, recalling the old saying ‘out of sight, out of mind’. And yet roots play vital roles in plant life, ranging from anchorage to nutrient absorption. Despite this, we know little about the timing and co-ordination of annual growth and development of roots in perennial plants. Thus, Thibeault-Martel et al. (Québec, pp. 667–674) have studied the annual pattern of root and shoot cambial activity and xylem formation in two gymnosperms, Abies balsamea and Picea mariana. At weekly intervals in the period May to November in three successive years, wood microcores were collected from roots and stems and were studied by standard histological techniques. In any one year, cambial activity showed the . . . [Full Text of this Article]
