- Observation During maturation, total soluble carbohydrates decreased and the sucrose to hexose ratio increased.
- Observation The sucrose to hexose ratio increased during embryo maturation.
- Observation Raffinose family oligosaccharides accumulated during desiccation.
- Observation Raffinose family oligosaccharides rapidly degraded at germination onset.
- Observation Sucrose decreased with germination.
- Observation Hexoses increased with germination.
- Observation Pinitol appeared with germination.
- Observation Healthy somatic embryos had a fatty acid spectrum dominated by linoleic acid.
- Observation Zygotic embryos mainly contained oleic acid.
- Intervention effect Highly embryogenic lines responded similarly to PEG except in sensitivity to high concentrations.
- Intervention effect At line-specific optimum concentrations, PEG reduced embryo germination.
- Intervention effect At line-specific optimum concentrations, PEG increased maturation efficiency.
- Intervention effect Appropriate PEG concentration improved healthy germinants per initial embryonal mass and accelerated the process.
- Intervention effect PEG did not improve the poorly productive line.
