Growing Seeds in Gel

Posted by edlincoln (My Page) on

Recently I heard about the possibility of starting seeds in gel. I like this idea for two reasons:

1.) You can see the roots growing in the gel, which has a coolness factor.
2.) I've been trying to start the seeds of some Native Shrubs. The seeds require stratification in my fridge. I really don't like keeping dirt in my fridge.

a.) Anyone tried this? Does it work?
b.) Which would be less likely to rot, jello (easiest option) agar, or that Water Gel used for cut flowers?

Jello is gelatin. It is commonly used for bacterial cultures. I wouldn't use that. Water Gel that is used for cut flowers are polymers that have been shown to hold on to water pretty tightly. I would think agar is the way to go. You would basically be starting seeds in what amounts to tissue culture. Yes, it will work. People start hard to germinate seeds in vitro all the time. You will want to make sure to sterilize your seeds before putting them on the agar.

here are a couple of good places to start.

Well there were going to be a couple of links, but yahoo groups are blocked, so you'll have to find your way to the yahoo tissue culture page yourself. It contains quite a bit of very valuable information.
