Linear correlation of diameter with diameter growth and height growth gave correlation coefficients of + and + respectively.

El Verde. The significance of this finding that tree diameter is related to sub- sequent growth, is that it indicates which part of the stand is responsible for most of the increment. However, with this information alone one might logically cut all small trees in an effort to increase growth (leaving the rapid-growing large trees). This practice might increase growth to some extent but it would be undesirable silviculturaily because it makes no pro- vision for replacement of mature trees when they are cut. - 65 - January 1943.
