internode, the part of the stem between nodes. The internode length varies between different vine varieties and with growing conditions. It is shorter with weak shoots, low temperatures, water stress, mineral deficiencies (especially of nitrogen), and the position along the shoot (with the nodes closest together at the base and the tip). Shoots on vigorous vines have long internodes, and are large in diameter. Measured lengths vary from about 1 mm to 350 mm/13.6 in but commercially used cuttings usually have internode lengths between 50 and 150 mm.
