LifeStage: Sporophyte concept has been removed

[mdoering]

The original life stage vocabulary had 2 root entries for life stages of all plants & algae: the haploid gametophyte and diploid sporophyte:
https://en.wikipedia.org/wiki/Sporophyte

Any other plant life stage should be a subclass of these 2. Seedling for example is a sporophyte phase. But a seedling, the plant right after germination of a seed, only applies to seed plants (spermatophytes) and not to algae, ferns or clubmosses.

[mdoering]

If the life stage vocabulary is supposed to be rich we should also add subclasses for gametophytes:

• Prothallus
• Protonema
• Thallus

Thank you - this is very helpful. Is this a correct representation?

Gametophyte
├── Prothallus
├── Protonema
└── Thallus

Sporophyte
├── Seedling

Should the following be children of Sporophyte?
Fruiting
Flowering
Gametophyte
Vegetative

[mdoering]

Fruiting and Flowering yes, Gametophyte is covered and Vegetative I am not sure what is actually meant with that in the context of a life cycle. Vegetative reproduction can happen in parallel to flowering/fruiting, e.g. in strawberries. Would you also want to add sexual reproduction as a life cycle stage? I can't see how that concept fits in here.

[CecSve]

Right, thanks.

No, I don't think sexual reproduction should be part of this. So:

Gametophyte
├── Prothallus
├── Protonema
└── Thallus

Sporophyte
├── Seedling
├── Fruiting
├── Flowering
├── Sapling

Remove Vegetative, but check the effect on mappings first (most likely not widely applied).

[mdoering]

while we're at it, add sapling to sporophytes
