Respiratory scaling is one of the most pervasive phenomena in biology providing a mechanistic insight into various growths spanning from herbs to trees. On the other hand, large parts of physiologists probably predict incongruence of whole-shoot respiratory scaling between determinate growth of bamboo-shoots by intercalary meristem and indeterminate growth of tree-shoots by secondary meristem. To explore empirically the effects of these meristems on respiratory scaling of the shoots, we measured 83 growing whole-bamboo-sprouts before leaf expansion, and 22 whole-bamboo-shoots with leaves, and then compared the respiration of these bamboo-sprouts and -shoots with our prior data of 254 tree-shoots from seedlings to giant trees (Mori et al. 2010). Astonishingly, we observed unpredicted consistent scaling exponents of bamboo-sprout: 0.841 (95%CI: 0.814 – 0.881), bamboo-shoots: 0.839 (95%CI: 0.783 – 0.899), and tree-shoots: 0.839 (95%CI: 0.818 – 0.857) in models of simple power function between respiration rate and mass of shoots on log-log coordinates. Thus, the whole-shoot growth traits and leaves did not alter the converged value of the exponents. The results imply the convergence of whole-shoot respiration i.e. energy flow of individual shoots. Thus, the converged energy flow of individual shoots may underpin a neutral relationship even within diverged species characterized by determinate and indeterminate growth.
