    I am starting early on my science fair project, this year. I'm going to do it big, because last year I got a score I wasn't proud of. Plus, I love science.
    Anyways, I want to do a project on the affects of brassinosteriods (and maybe other things) on salt stress induced plants. I know the question I'm about to ask may sound a little ridiculous, but I don't know a lot about it.
    So, I need an answer to my question.
    How exactly do you induce salt stress on a plant? I know of some common species to use, but how do you increase salt concentration? Anything else helpful would be great(:

    You could dillute the salt into a water solution and apply to the roots of the plant... you could also apply salt to the leaves of the plants with a spray bottle.

    Well, salt in general, has as a result to accumulate a large number of water around it. This has as a result that the plants get dehydrated as their roots can no longer suck up the water.

    Spraying saltwater on the leaves can even have the opposite effect and hydrate the plant more, as with this salt, the leaves themselves will be salty, and that way they can attain this water longer, and in some cases even more water.

    Salt water on roots though will drain the plant dry, and probably kill it easily.

    The best way to even out salt concentrations around the plant, is by growing it on fiberglass (transparency), and using a seringe to apply the salted water to all the roots.

    You should check what plants need to be able to grow on fiberglass though, it's interesting.
    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..

    interesting...
    salt on the leaves was just an idea

    Surely dehadration isn't the only problem with salt? and surely by your logic salt on the roots can help provide moisture the same way it can on the leaves?

    I did hear that if a plant is dehydrated it starts to produce toxins that will kill it... somehow sugar can be used to undo this damage, i'm not sure about the science behind that...

    Salt is one of the best dehydration technique for your plants. If you don't want to make plant very high than you have to put on the salt. the salt is used for opposite effect of your plant so always avaoid the salt and try to use some different technology for hydration.
