The early spring growth of timothy was found to be negatively associated with the fructose concentration in the tertiary shoot. A positive correlation between spring growth and N fractions was established, the water insoluble N fraction being most closely associated with spring growth. While it is generally accepted that high production following a period of stress requires an adequate carbohydrate source, evidence is presented to show an internal source of nitrogenous material for rapid synthesis of new protoplasm may be of greater importance.
