In the present paper, one of 3/2th power laws is derived theoretically based on the assumption that growth goal (W) in this ρ-logistic growth quation is constant. This theoretical solution includes all growth stages of the plant stand regarding the full-density curve, and gives (w/w₀{(ρ/ρ₀)∧β+δ}=1, δ=w₀/Wc. Here, w is the mean plant weight, w₀ is the initial value of w, ρ is the stand density, ρ₀ is the initial stand density, Wc is the goal value of w and β is the power of the 3/2th power law. This equation is called the axpanding 3/2th power low. If we assume δ→0 in this equation. We obtained the normal formula for the 3/2th power law, and w(t) equation for the 3/2th power law is solved by substituting the ρ(t) formula of the previous paper into the nomal formula for the 3/2th power law. This equation is as follows: w=w₀f exp(β(t-t₀)∧m/α). Here w₀f is the initial value of w for the 3/2th power law, and t₀, m and α are the constants. On the other hand, the expanding formula for w in the previous paper again yielded the same way by use of this expanding 3/2th power law as growth goal (W). Furthermore, This w can be used as new growth goal (W) in the ρ-logistic growth equation, and the solution of the ρ-logistic equation under this new growth goal represents the w-ρ curve for all growth process in the plant stands. A result which supports the assumption obtained by fitting this solution of the growth equation to SPURR et al., data.
