Well, I agree liquid would probably be better, but for small quantities, powder seems the only

thing available retail.  I don't think grafting will work at this point, as I've found that when buds

start to push they generally don't graft well.  I had thought that callus formation was associated

with rooting, but I did realize that not callusing did not necessarily mean that rooting

would be successful.

<<If Chris you only have two cuttings you are better to have a good

yield if you do your grafting now. If your intent is to trial plant

rooting hormones then you should be trials with a larger number of

cuttings. malus is difficult to root and the possibility of two

cuttings rooting is low.

Then, you have three products at hand. NAA in 1% powder form is quite 
unusual. The only commercially produced product that we know of with 
NAA in dry powder form is Rhizopon B which is only made in %0.1 and %0.2.
It is only available in Holland and perhaps some local European 
countries for specialty crops such as carpinus (hornbeam), but even 
then it is rarely used and there are better choices.>>
