Figure 2From: Modelling microfibril angle variation in New Zealand-grown radiata pineIntra-stem variation in MFA predicted by (a) a modified logistic function with a linear relative height term, (b) a logarithmic relative height term and (c) a modified Michaelis-Menten function with a linear relative height term and (d) a logarithmic relative height term. Parameter estimates for the models are given in Table 5.Back to article page
