From: Node frequency alters stem biomechanics and hydraulics in four deciduous woody species
Modulus of elasticity (MOE), modulus of rupture (MOR), stem density, and xylem-specific hydraulic conductivity (Ks) varied with node frequency. Each point represents a stem sample. Node frequency was associated with MOE (F1,143 = 7.00 P = 0.009), MOR (F1,143 = 4.63 P = 0.033), stem density (F1,143 = 27.38 P < 0.001), and Ks (F1,143 = 6.54 P = 0.012). For MOE, MOE, and Ks, there were no interactions between species (P > 0.05 for node*species term), but for stem density, there was a significant interaction between species (F3,143 = 3.74 P = 0.013). Lines are included to assist with the visual interpretation of patterns in the data. Species are indicated with different symbols within each panel and species abbreviations are included in Table 1
