Does a plant continue attracting pollen after fertilisation?

What I mean is:

The ovules have all been fertilized by pollen grains.

The seeds are forming.

Does the stamen still produce pollen?

Do bees and other pollinating creatures still visit the flowers and deposit pollen? If so, what happens to this pollen?

Thanks.

 

Hard questions SimonZ - but here goes.

Pollen is produced in a time period, irrespective of what is going on.
For example, if I cut all the female flowers off my courgettes the male flowers would carry on producing pollen

I think bees (I stand to be corrected here) leave a scent on flowers they have visited so that they don't waste their energy visiting again if there is nothing to be gained.

Pollen which is not used is just wasted. It's as simple as that.
Think about the human reproductive system..

 

Thanks for your answer. I am studying this subject and appreciate any help!

 

Off at a tangent, but I always panic when the male flowers on Sweet corn start shedding pollen - female silks nowhere to be seen, and then within 24 hours there they are!

But I think the pollen stops before the cobs are fully fertilised (probably doesn't matter than much in the wild, but the cook certainly doesn't like partially pollinated cobs appearing on the dinning table!) so I plant successively in an up-wind direction in the hope that later tassels may pollinate the earlier crop's silks as their male flowers stop producing pollen. I'm probably only fooling myself ... but ...

 

I know what you mean about the male pollen running out before all the silks are fertilized Kristen. It appears in such showers to begin with and I shake some into a poly bag for later use. It seems to work and get all the cobs fully fertilized. You might want to give it a try next year.

 

Not heard that one before, thanks! Nobel prize here I come!!

 

I think flower fertilisation is a fairly complex subject, and its well above me.

All I know is that some plants are self fertile and some arn't, if a plant is self fertile its capable of producing seed even if the flower gets pollen from other flowers on the same plant.
If its not self fertile it will need another plant of the same species to pollinate it.

Flowers have all different kinds of ways of making sure they don't pollinate themselves, usually the pollen is shed before or after the female bit has become receptive :D

 

Thanks. I really appreciate everybody's input on this question.

 

You're welcome Simon.
Very interesting questions you ask.
What course are you doing ?
