Moving fluids in plants: Celery?

Question

I did this biology lab, where I put a celery stem in a cup of water along with food colouring and comapred it to a celery stem in water with food colouring AND salt.

I'm not too sure on how to answer this question:

Can we detemine how a chosen factor(salt, sugar, temp., etc.) influences the rate of water movement through plant stems?

If you're using a website, a reference would be nice :)

Thanks.

btw: You don't have to type it all, just give me a link if possible!
