Last year I scarified a group of guava seeds, both mechanically (filed endocarp) and chemically (acetic acid). Neither worked. Of the 5 control seeds I had used (no scarification), 5 germinated, 4 made it up to early vegetative, & still thrive. A majority of the sources I had used back then painted seed scarification as a standard practice in commercial guava seedling germination practices. Yet I obtained opposing results. Go figure. I'm wondering if olive pits would respond well to scarification. A few sources say the endocarp needs to be excised. It does not work--my seeds rotted. So scarification seems a likely priming method for these last 2 olive seeds I have left. Next on my xmas list: some H2O2. Thanx 4 blogging on scarification! Scarification can be a pain to do right.
