Number of flowers
I take it as you mean with pollination the full process, i.e. from pollination up to capsules.
Then it nearly sounds like a perpetuum mobile. Flowers are a sink. And certainly the initial growth of the capsules also takes a lot of energy, though later on capsules of certain species have such a shape and green color they might be energy self sufficient, but not really a source? And mineral-wise they completely rely upon the roots. The more it gets pollinated the more flowers it produces and then again gets more pollinated and again more flowers I don't see that. Rather the opposite, after heavy pollination some skip the next flowering altogether, or with fewer flowers. The below photo is of Aerangis confusa, two separate plants, one with flowers, the other one only with seed capsules. Many of them are now in flower, but the ones who got pollinated last time have less flowers or skip altogether. This species has rather brown capsules from the onset and the ones in the photo still have a few months to go before opening. Also in the tissue it is brownish, no signs of chloroplasts. I guess they are brown not to entice pests. A number of species flower from the same location on the stem, but mostly after the previous inflorescence is only a stalk, I guess some light reaction. @Ray, sure orchids do flower when they are comfortable with their resources, some also flower as a last resource, this is very clear when a host tree, or host branch has died, all its resources are used to flower abundantly to escape its location. |

Is the production of fruits and capsules “budgeted” within the production of Inflorescences/Flowers? Or, if not, is it another X amount of energy that the plant needs to divert to produce seeds? ---------- Post added at 05:58 PM ---------- Previous post was at 05:57 PM ---------- What books can I read to soak up these things?

“Budgeted” is an interesting way of describing the concept that was rattling around in my head.
As far as the plant is concerned, I would think reproduction would include all of the above. |
