Four lots of trees were outplanted and grown for their first season at Davis, California, in 1963. Three lots were evergreens (1- and 2-year-old Schinus polygamus and Melaleuca linariifolia), and one was deciduous (Fraxinus holotricha). The average seasonal growth can be described as second-degree polynomials plus pure sine curves. The three lots of evergreen trees had similar average growth, with variations in the constants of the polynomials and variations in the periods and time of peaking of the sine components. The average seasonal growth of the deciduous lot was much less, with the coefficient of the second-degree term in the polynomial trend practically zero. The sine component was also different from all the other lots and was statistically insignificant.
