Pictured is an obesum seedling of "Sawadee" sown May 13...I decided to try to force early branching by careful removal of the main growing point with an Exacto knife. You can see here the new growth in the leaf/stem juncture in 2 places below the main growing point. I also did this with another obesum seedling sown May 13 that has not responded the same--it just grew back the main point with no branching as of yet.
About 4 days ago I repeated the experiment with 5 more seedlings--three more obesums from the May 13 sowing and two S1/Golden Bell Thai socos that were sown May 28. So far, only one of the S1's has new growth that I can see (with one of my magnifying lenses) and it has 4 new growths at various leaf/stem junctures but no new main point growth--go figure!
So....if my success rate improves with the 5 latest attempts, I plan on repeating the experiment with more of my 130+ seedlings.
