Other claims from this paper (10)
- Observation Ripening seeds gained dry weight faster than fresh weight, lowering moisture to 60%.
- Observation Maturing seeds lost water without gaining dry weight.
- Observation Excised embryonic axes above 70% water failed to grow.
- Observation Embryonic axes acquired full growth potential at 55–50% seed water.
- Observation Axes could grow before acquiring desiccation tolerance.
- Observation As cells matured polysomes disappeared and free ribosomes appeared.
- Observation Mitochondrial matrices became optically empty and cristae less swollen with maturation.
- Observation Chloroplast grana disappeared as seeds matured.
- Observation Cotyledon cells showed similar maturation changes.
- Mechanism Authors interpreted structural changes as preparation for desiccation tolerance.
