Pathways from large axons were designed not only to attract glial cells, but also to induce them to form myelin internodes of appropriate size for the axon.
In each step, all apices and internodes are transformed in parallel by their respective productions.
Mean values between medium and low treatments did not differ between any pairs tested for height, number of internodes, number of internodes with branches, and dry mass (Table 1 and 2; P [is greater than] 0.
Bamboo canes are effectively smooth, uniform cylinders (although some are prismatic in cross section, such as Chimonobambusa quadrangularis) between 3 and 6 in (8 and 15 cm) in diameter, with alternating nodes and internodes, like all other canes.
The probability of congruence depends on the length of in-ternodes between bifurcations or speciation events and the effective size of the ancestral populations in the internodes of the species tree.
At the end of each growth trial we measured: (1) plant height; (2) length of three internodes beneath the most recent fully expanded leaf; (3) area, fresh mass, dry mass, and petiole length of three top-most fully expanded leaves; (4) total number of leaves; (5) total number of internodes; (6) number, internode number, mass, and length of branches; (7) total leaf area and dry mass; (8) petiole dry mass and length; and (9) root dry mass.
