In tetraploid cannabis (4n), the stem often expresses a compressed internodal architecture, where four distinct nodes initiate within the vertical space normally occupied by a single internode in diploid plants.
🔬 What is actually happening structurally
- Internode compression
Instead of elongating between nodes, the internode remains short, causing multiple node initiation events to occur at nearly the same vertical position on the stem. - Four discrete node origins
Each “stacked” node is a true node, not a split or mutation:- Each has its own axillary meristem
- Each can produce its own lateral branch, leaf set, and floral site
- Nodes may be radially offset (not perfectly opposite)
- Shared vascular convergence
All four nodes connect into a thickened vascular ring, which is why tetraploid stems often show:- Pronounced vertical ribbing
- Increased stem diameter
- Enhanced nutrient and water flow capacity
🌿 How this differs from a diploid node
| Diploid (2n) | Tetraploid (4n) |
|---|---|
| One node per side | Four nodes clustered |
| Clear internode spacing | Internode compressed |
| Two axillary meristems | Four axillary meristems |
| Predictable branching | Dense, stacked branching |
| Smooth stem | Ribbed, reinforced stem |
🌼 Reproductive implications
Because each stacked node contains a fully functional meristem, tetraploids often show:
- 🌸 Multiple floral initiation points at the same height
- 🌼 Clustered anther or pistil emergence
- 🧬 Larger floral organs
- 🧪 Larger pollen grains (often reduced total count)
This is why tetraploids are often described as “node-dense” rather than “fast-growing.”
🧠 Breeder interpretation (plain language)
Instead of spacing nodes vertically, the plant stacks four growth points into the same spot, creating a dense, reinforced junction capable of supporting more growth and larger reproductive structures.
🏷️ fo-SHO-style one-liner
Tetraploid structure compresses four true nodes into a single internode, stacking multiple meristems at one growth point and producing dense, reinforced architecture.
