Kievnstavick - Celtis occidentalis North America #1

[Kievnstavick]

Hello all who's curiosity got the best of them and stepped into the Celtis Contest zone.

Although titled for a specific species, I have aquired from Sheffields seeds a select variety of Celtis that caught my eye (and were also available to purchase from my trusted source). I have approximately 50 each of the seeds.

This first forum post will be to document the germination process of the three species. Afterwards, I plan on making new threads for the different species. Once the seedlings are past their first potting up and make it through the summer, I'll make individual threads for a good selection if them that show the most promise.



I received the seeds yesterday, but I didn't get to them until today.

I gave each packet of seeds a 30min soak in GA3 (ppm unknown as I kinda just winged it. It was approximately 1/32 tsp to one small baby food container of water). After the bath, I plopped the seeds into a humic acid and kelp solution to soak for 20-40 hours.

My current plan is to sow the seeds tomorrow after work into seed trays then leave them outside. I plan to retain about 5ea of the species to attempt breaking the seed coating and give it another long soak as a means of circumventing the dormancy requirement.

As I have approximately 60 days left of cold weather, we will see how these will germinate. It should be fine though.

Today I planted the seeds into a 10x20 tray filled with a 50/50 mix of small-sized pumice and coco-coir.



After the seeds were placed, I separated them with medium sized vermiculite (mostly because I didn't want to use my usual pumice for the barrier) as a way to visually tell where each species was sown. I covered the seeds with medium sized spahgum moss that I ground.

The seed tray will go outside tonight as I forgot to take the tray out while getting ready for work.



In total I have:
55 Celtis julian
57 Celtis koraiensis (with a single floater)
64 Celtis occidentalis (North America)

I took 5ea of the species aiming for the larger seeds for ease of holding and sanded through the seed coat to circumvent the stratification period. They were placed back into my solution for another 20ish hours.



For the sanding, I used 100grit sand paper and removed the outer coating until I could just start seeing a colour difference. The sanded process involved a few passes over the sand paper. Stopping frequently to look for potential break through and to make sure I didn't over heat the seeds. I sanded in at least 3 spots to ensure that the swelling seed could break through the coating if the seed coating didn't soften enough.



Pictured above is to show what sanding too much looks like. In this case I broke through the seed coat a lot quick then I anticipated. The seed itself doesn't look harmed, but I wouldn't be surprised if the cotyledon shows some minor damage once they sprout. Shouldn't be an issue as I have had seeds live with worse damage pre-germination.

My plan with these 15ea is to sow them into small pots and germinate them in my grow tent while I wait for the spring weather.
