Have any plants been raised in hyperbaric conditions? What was the result?

Question

Hyperbaric as in a hyperbaric chamber. Since this is about plants then I would assume it would have increased air pressure consisting mainly of carbon dioxide.

Answer 1

Here is one study with good results.

I know that they have done studies with plants where they add more Co2 in pressurized situations and the plants seemed to thrive in that environment.

I hope that this helped.

Answer 2

Most roses are grown in green houses with a increased amount of carbon dioxide. This makes them grow better.
