Observations in Java and Ghana have shown that sugar-cane (Saccharum officinarum) varieties may considerably differ in outward appearance of the leaf spindle. In some varieties the leaf spindle is comparatively ‘closed’ (POJ 2878), in others ‘open’ (Ghana 1). Likewise the differences in length between successive leaves, which are not yet full-grown, may be comparatively large (POJ 2878) or small (Ghana 1). Investigations recently carried out in Ghana confirmed the supposition that these differences are partly caused by differences in growth distribution. By refining an old but still suitable observation technique it was further possible to obtain new information about the course of the elongation processes in leaves and stems of sugar-cane.
