You're not getting the point are you?
I'm guessing you came to that conclusion after reading what 2 maybe 3 sentences?
Firstly they're looking at the signalling technique - How do the roots signal to the rest of the plant they're restricted? it's not just limited roots therefore limited nutrients - there's probably hormonal signalling going on here.
Secondly the way the roots then behave is interesting:
"When they reach the edge, they send some kind of signal to the shoots to say, 'there's a problem - stop growing'."
Each plant appeared to be trying to escape its pot; more than three quarters of the root system was in the outer half of the container.
*"The inside of the pot is hardly used,"* explained Dr Poorter.//
Thirdly this happens even in very large pots:
//"Even the largest pot was not large enough not to limit growth."//
You really ought to think about stuff a bit more before jumping to the conclusion that scientists are there doing stupid waste of time experiments
Think "Is it even remotely possibly they might know more about it than I do?"
