The shoots growing above the branches of dragon fruit seedlings are leaf buds or flower buds, with more leaf buds.
The dragon fruit is a climbing succulent. The plant has no main root, and the lateral roots are distributed in the shallow surface soil layer, while there are many aerial roots to climb and grow. The rhizome is dark green, stout, up to 7 meters long and 10-12 centimeters thick. Ribs flat, wavy edge, stem nodes at the growth of climbing roots, can climb on other plants to grow, each section of the stem node depression with small spines.
Because of the long-term growth in desert areas, the leaves have degenerated, photosynthesis function by the stem. Inside the stem is a large number of thin-walled cells full of viscous liquid, which facilitates the absorption of water during the rainy season.
Extended information:
Aerial roots grow because the dragon fruit itself is not upright enough to be hard. It can't absorb sunlight in all directions like a tree can, and when the aerial roots are born and attached to surrounding objects, it allows the stem to stretch and absorb sunlight better.
