The stem consists of internodes spaced between the nodes, with attached leaves. The number of nodes and internodes is equal to the leaf number, all three having a common origin in the phytomer. Shoots of temperate grasses have compacted or untelescoped nodes (without internode elongation), which, until elongation after floral initiation are positioned below the […]

In most of the Dicotyledons and Gymnosperms after the completion of primary growth of axis in length and diameter, further enhance in diameter takes place due to the formation of secondary tissues. In the stelar region a cambium ring is produced which gives rise to secondary xylem and phloem, and in extrastelar region the cork […]
