- ItemSECONDARY ROOT AND STEM GROWTH IN A CHILEAN MATORRAL SHRUB (COLLIGUAYA-ODORIFERA-MOL)(1978) AVILA, G; ARAYA, S; RIVEROS, F; KUMMEROW, JThe annually produced xylem of an individual shrub of C. odorifera Mol. (Euphorbiaceae) was analyzed for 4 consecutive years (1972-1975). In addition to the primary growth, secondary thickening growth in stems and roots contributed to about 20% of the biomass produced. A survey of the shrub''s bark biomass (all tissue peripheral to the vascular cambium) showed that contributions to biomass by bark in smaller branches and roots (diameter < 0.5 cm) were 56 and 90%, respectively, while in larger stems and roots (diameter > 0.5 cm) bark contributions to the dry wt were 22 and 53%, respectively.
