One tree: The effects of cloning trees on their reproduction

[sableg]

So I recently read about an artist named Natalie Jeremijenko who created a project she called "One Tree". They cloned thousands of genetically identical seedlings of the paradox walnut tree derived from cell cultures of a single plant. These clones were initially grown in a lab and experienced the same environmental conditions then they were to be planted throughout the San Francisco Bay area. Obviously the trees began to look different because of their different environments influencing their growth.

Anyways where I was going with this is... If cloning trees became a way of the future (obviously wouldn't happen because of our society) but would trees be able to reproduce seeds properly if we stopped cloning them or would lack of diversity and become for lack of a better word "inbred". Or would the pollen of say flowers suffice in fertilizing the trees seeds. Or are trees asexual so they would just be able to reproduce with their own identical pollen.

I know this question is somewhat out there but it really sparked my interest

I guess you have never had a plant, have you? Or at least, you have never cut it to reproduce it, right? Otherwise you couldn't ask so stupid.

Cloning (what kind of cloning, by the way?) is nothing else, than process used for thousands of years by agriculturists and gardeners.

Ha-ha!!!!
even google-search on "cloning of trees" gives "cutting for reproduction"
or may be you mean some magic in laboratory in tubes??
