Durian Seedlings - Week 5
Firm, plump, and healthy, which is a good sign. I don't see obvious signs of rot such as blackened tissue, mushiness, but fungal growth?.
A few observations:
- The seed coat has split naturally, which is normal during germination.
- The exposed inner tissue has a healthy orange-brown color and appears turgid rather than collapsed.
- The surrounding medium was left to fry out however is still quite most, which durian likes during germination, but prolonged waterlogging can cause the seed to rot.
- No presense of emerging radicle (root) or shoot yet, so it may be in the very early stages of germination.
- The orange seed part is healthy and wet.
- No rot, though there may be some form fungus becoming visible.
- Firm: Healthy. (y)
- Soft: Unhealthy. (N)
- There is more concern about this seed than the first two.
- Compared to the first week it seems to have lost it's sprout (root)
- The dark area on top looks different and may indicate dead tissue.
- No visible sprout is present yet, although some healthy orange tissue remains.
- Firm black tissue: May simply be damage or discoloration.
- Soft black tissue: Likely rot.
- Seed 1: Healthy.
- Seed 2: Healthy and growing.
- Seed 3: Uncertain, approximately 1–2/10 chance.

Final Thoughts - Referenced
Do not discard the third seed yet. It may still germinate successfully. Leave it in place for another week and monitor it closely. If the condition remains stable and a root emerges, it may survive. If it becomes softer, darker, develops mold, or produces an unpleasant smell, it is likely failing. The remaining orange tissue suggests it is not completely dead at this stage.
This one is unlikely to make it
