That's very interesting stuff Bradon. I felt elevated Boron levels played a big role in triggering megas. This data pretty much debunks my theory.

Well it depends, if the dandelions are immune from needing boron (because they store significant reserves of calcium from the previous year?) then maybe they're not a good indicator of the necessity of boron. The other soil test was done in the spring so maybe there was sufficient boron when the megas formed but it had since washed out of the soil.

You're making me think which is good. I need to study the role of boron.

This is WAY in the weeds, but i like the weeds LOL. I think you do to. This excerpt is from a paper called BORON IN PLANT STRUCTURE AND FUNCTION by Dale G. Blevins and Krystyna M. Lukaszewski......

"Robbertse et al (106) found a boron gradient from the stigma through the style to the ovary and showed that pollen tubes of Petunia grew toward higher boron concentrations. Perhaps boron is a chemotactic agent for pollen tube
growth through reproductive tissues. This idea is consistent with the high boron concentration generally found in female flower parts (32).

The results of pollen growth studies are consistent with boron-complexing cell wall polymers, while the lipid thermostability results show that boron is
important in membrane structure and function. Whatever the mechanism, the role of boron in reproductive growth is particularly striking. The uniformly
high boron requirement for reproductive growth across the plant kingdom is intriguing and indicates similarities between reproductive structures, so unlike
cell walls, perhaps the composition of the pollen tube wall is similar across plant species. Gauch & Dugger (32) quoted Lohnis (69), who said that “it is
quite conceivable it will be the study of pollen which may elucidate the veryfundamental part boron plays in the biochemical processes.”

I've been reading some crazy stuff. Searching boron, meristem, and fasciation. Not afraid of weeds.
