There was an article in a past Nursery Managment trade magazine about 
some experiments with spraying hosta leaves with cytiokinins.  They 
took potted hostas with one stem and sprayed them with 40,000 ppm 
cytokinin, I forget just which cytokinin,  It induced the side buds to 
break dormancy and produced a much nice looking potted plant.  The 
idea was to be able to spray this on potted hostas some time before 
they would be sold at a nursery or garden center.  Unfortunately, a 
40,000 ppm (4%) concentration of any cytokinin will probably end up 
being very expensive.  

I'm fimilar with 2iP, BAP, Zeatin and Kinetin, but what is TDZ?  This 
must be a new one that I haven't heard about, but then it's been 20 
years since I last did TC work.
