Modified corn starch as a gelled intermediary in rooting

Hi all,

Years ago I ran a plant tissue culture lab and used modified corn starch as a gelling agent. I found it worked okay as a gelling agent and the bit of zeatin in the MCS promoted cell growth without having to add any other cytokinin. Has anyone used it as a gelled pre-dip before using powdered rooting hormone? I was staring at my pantry shelf this afternoon when the thought hit me that it might help in three ways: 1) callus formation could be sped-up due to the bit of zeatin, 2) the cutting would have a higher water retention near the callusing tissue and 3) the cambium and various pores would not be blocked by the powdered hormone mix hopefully reducing end rot.

Thoughts?

I will be trying it out this season to see if it has any merit.

Thanks for your time and I hope all good things come to you and yours!

Will there be a problem with lack of sterility in rose cuttings and fungal growth instead of roses roots? I guess it depends how much you apply.
