Pinus radiata seedlings were raised from seed and grown in perlite culture at five levels of N (urea) supply: 100, 20, 5, 0.5 ppm, and no N. Increasing the N supply above 0.5 ppm N both increased the growth rate and changed the distribution of dry matter within the seedlings. With increasing levels of N there were: (1) greater stem basal diameters in proportion to heights; (2) greater numbers of branches; (3) greater weights of branches in proportion to stem weights; (4) greater weights of shoots in proportion to root weights. The concentrations of N in the shoots and roots of seedlings in the 20 ppm N, 5 ppm N, and 0.5 ppm N treatments were very similar. Forest Sci. 23:64-68.
