| 520 | |a"During the past year, papers by Boughner and Kendall and Holmes and Robertson have been published on the subject of growing degree days and the growth of vegetation. It has been pointed out that the amount of growth in many plants is roughly proportional to the accumulated excess of the mean daily temperature over a threshold value of 42° F. We are further reminded that temperature is only one of the primary factors controlling the growth of plants, and that water supply, light and soil type are also important. In southern Ontario, however, where the light factor in spring is constant over the area and in most years there is an ample water supply for growth, temperature is usually the most important variable, and the response of vegetation to temperature is usually readily apparent"--Page [1]. |
