Summary

Increments of fibre, sucrose and reducing sugars per cane were estimated for 12 varieties of sugarcane for successive periods in plant and ratoon crops. Sucrose production increased only as that of fibre and reducing sugars fell. Dry matter production per unit fresh weight of leaf blade was negatively correlated with an estimate of gram days of leaf per gram fresh weight of cane. In a further study the net assimilation rate of one variety was found to remain fairly constant over a period of six months at 0·55g/dm2/week. It is suggested that breeding should seek to reduce leaf area ratio while maintaining sucrose percentage cane.
