Out of context, from

<Skoog and Miller’s conclusions
– -formation of shoots and roots controlled by a balance between
auxin and cytokinin
– -high auxin/low cytokinin = root development
– -low auxin/high cytokinen = shoot development
– -concept applies mainly to herbaceous genera and easy to
propagate plants>
Maybe what I'm seeing in rooting behavior in different cultivars has to
do with their auxin/cytokinen balance? (or is it cytokinin? this site
spells it both ways) Those with more cytokinen grow more tops & have
less resiliency, those with more auxin grow more roots and are more
resilient? At my garden, east of iris heaven.
Janet, where do you get the cytokinin you use, which is it, and if you
were going to try to induce adventitious buds (root buds for me, not
shoot buds) on irises, which would you use & how much? Is wounding the
only way to get it into the iris tissue? As if I don't already have
enough rot inviting insults to rhizomes here.....
