One of the ways in which grasses respond to varying conditions is by adjusting the growth rates of their different component parts relative to their overall growth rate. When plants are grown in constant conditions, increasing age brings about a decline in the growth rate of the leaf lamina component and an increase in the growth rate of the root component relative to the plant growth rate. Variations in temperature, photoperiod and in the daily amount of radiant energy received by the plant do, however, influence the distribution pattern of growth within the plant.
