Abstract
In 1972, switchgrass (Panicum virgatum) grown in the field at Madison was harvested at early anthesis. Shoots were separated into the individual parts at 0600, 1200, 1800 and 2400 h on 3 days. Diurnal trends were clearest in the inflorescence, leaf blades, and the upper sheaths and internodes, but were not always statistically significant. Contents of non-reducing sugars, total sugars and starch tended to increase from 0600 to 1800 h, then decrease to until 2400 h. Diurnal changes in the content of reducing sugars was small in all plant parts. Basal sheaths and internodes tended to increase in starch and total non-structural carbohydrates from 0600 to 2400 h. Sugars were probably being translocated from the upper leaves to these sink areas all day, but particularly after 1800 h. Results indicated that grazing in the evening might be advantageous particularly in terms of herbage energy content
