Well if you can have zero gravity then you can as well grow a tree at zero gravity. Interestingly they will not look much different since the aim of trees is not to grow against gravity but to grow towards the Sun. read more

A plant grown on the International Space Station: The complication that needs to be overcome is that plants make use of gravity when planted to orient themselves (as they can't rely on being planted the right way up), so that their roots go down and their sprouts go up. read more

Wood wont have the same strenght. When a tree grow at an angle it will develop stronger material on the opposite side of the slope so he will straighten up. They actually grow tree in zero gravity in order to isolate this process so they can induce it at will and grow stronger tree thus better stronger lumber. read more
