Germination of the expansion phase is in full swing. Some seeds pop like crazy, some not at all. Here is an account of last five days.
The other table:
A lot of data here, but here is a synopsis. The most prolific species from germination standpoint was Blue Spruce from Arizona. 86% seeds popped seed casings in seven days. This is without stratification. Very impressive. Same species but from Colorado is not far behind with 76%. New Mexico samples are germinating slower, in line with most other species.
However, none of the germinated Blue Spruce seeds are yet to show any starter leaves from any of the Blue Spruce samples.
The leader of the green leaves is Giant Sequoia! A respectable number of seeds germinated, 20%, but the interesting part is that 5% already free of the casings.
Doug-fir and Sitka Spruce despite different methods of germination (Sitka directly in peat moss while D-f on paper) show very similar results both have about 20% casing breach and 3-4% stand with green leaves.
Western Hemlock shows a respectable 28% casing breach but no green leaves stand free.
Finally, one species remain stubbornly dormant. Pacific Silver fir did not show any signs of casing breach on filter paper nor in peat moss with 50 samples in each method. Another 100 seeds are stored in the fridge at 0C at this time.
