Has anyone developed a technique to stimulate adventitious root formation on the hypocotyl? (Giant Pumpkins)
I have gotten hypocotyls over 12" in experiments (buried the hypocotyl as it grew in total darkness) but did not get any adventitious roots. TY John

you would get the most help if you used lamens terms but from what i get out of it the hypocotyl root must be the root that forms at the bottom of each leaf node. i always thought it would be sweet to powder each of the plants secondary tap roots with rooting hormone. it would seem to me to stimulate adventitious roots to some extent.

There´s a report on bp.com, haven´t tried it but it seems as if patience would be essential, perhaps the roots form after some weeks?

This won't help answer your question, but here's an old photo showing long hypocotyls when left in a cooler.

I did try planting the longest (over 24" when buried). Unfortunately the plant soon died, so I was unable to see any possible results.

just FYI, in lamens terms

hypocotyl - the part of the stem in between the cotyledons and the radicle (first root when the seed germinates)

adventitious roots - roots that are not part of the original root system, so to speak, and grow when conditions are right (for example, when you bury a vine and the result is that a root from the node you buried grows, whereas it otherwise wouldn't)

Some plants, like tomatoes, will grow adventitious roots on the hypocotyl if the hypocotyl is buried.

The question here is getting adventitious roots to grow on the hypocotyl of a pumpkin plant.

I always try to put dirt right up to the base of the cotyledons.I assumed that tissue was capable of forming extra roots.Ive never tried rooting hormone there-have tried it at leaf nodes.Matt debacco would have some ideas on rooting in general with his experience with propigating clones/cuttings.I saw a picture of the 1818.5 bryson still in the patch.Had the longest most impressive roots coming off all vines near the pumpkin that Ive ever seen
