I just used the "Seek" app on the tree in the third photo above.  It says that is some kind of willow, and looking at it closely, I agree.  So apparently my apple seedling died and a willow tree grew in the pot.

I have done a bit of reading up on Parthenocarpic pear experimentation done in California during 1970 and 1971. Apparently at least some cultivars such as 'winter nellis' that normally need a pollinator to fruit can still be induced to fruit without pollination in treatments with Gibberellin spraying. The final results are seedless. That's one way of escaping codling moth the organic way, or is this just applicable for pears and not apples? 

At least that's something being tested out on a very limited basis right now and a few years back at my house where I inter-graft pears and apples. The apples tried so far are not very many great cultivars like the kinds you breed. If I can find larger apples worth eating and if they can be working well on my hybrid Chinese pear like some other smaller apples have then "if" they, as far as the seeds are concerned, stay viable then it means I answered my original question of how Parthenocarpic pear production differs from Parthenocarpic apple production. (the former are seedless, the latter might have seeds)

It's technically a breeding development possibility (in Parthenogenesis) that may be useful to trial almost clone-like features from an apple that's almost good except you might want to tune out some minor variables like apple browning, like the selection of a mutation being noticed from a branch, or a new sport. 

The method might be possible using cultivars noted for full time high levels of Gibberellins (ie. GA3). The cultivar 2-2-40 (50% chinese pear 'mishirasu') by Peter from his ventures in breeding at Vashon Island WA came across this special GA cultivar by accident about 30 years ago! 

This is still rather speculative, but even so, if you have the time that it's going to take to prove this out, then in the long run we are doing what students have problems dealing with long term. For example Peter sold his farm and passed away a long time ago. Good luck !!

Thanks Rooney.  That is all way over my head but if what I'm doing can assist you somehow, please let me know.

I do wonder about the seeds from the "Tolowa Dunes" apple.  I ate 6 apples and found only about 6 viable-looking seeds among all of the apples.  Then I lost them in the refrigerator for 2.5 years.  I attempted to sprout them this spring.  Two sprouted, but one died.  The lone survivor was about 3" tall when I forgot to water it on one of those super hot days and it too died.  Or perhaps it had some disease.  I guess I'll have to go back to Tolowa Dunes someday.  Or maybe someone in this forum will visit it :-).  But anyway the parent tree is all by itself, at least a few miles from any other farms or homes which may have an apple tree or two.  And I did not see any other wild apple trees in the park.  So I'm curious about pollination, fruiting and seeds when a tree is very isolated.

Malus Fusca is common so before you try and satisfy the curiousness you have to investigate pollinators that far down at least know (before next time you go) that sometimes M Fusca is hard to find. Since I know where you live the first thing you might want to do then is learn how often times that Fusca trees also lack fruit to make your pollinators that much harder to find. For example there are a few Fusca trees located at the near NE corner of the fire hall and just on the borderline side of Dog Park. Last week I found two fruits on three trees there. 

I know you will investigate or at least take this into consideration about the fire hall because your a curious guy (as am I) and the price of gas is high.

Originally you posted and offered madrone seedlings (arbutus menziesii). Just like you I also had some once. It's hard to tend to watering schedules so you lost your apple seedlings but I lost my madrones after a few years due to my neighbors lawn mower. They do look pretty cool along an edge of a park or the seashore. The wood must be the most dense I have ever seen. I pulled one from that area on your map after a lighting strike and a storm. Pruned down by a strike and leaning over is pretty amazing! 

I got a "native apple" from a friend which I assume is Malus fusca.  It always flowers but has never produced fruit.  But I use it for grafting.

I'm not familiar with the fire hall that you speak of.  But there are a LOT of fruit and nut trees near my work in Hazel Dell. There are many nut trees in the dog park, and I have collected a lot of nuts from there because there tend to be very few squirrels in a dog park!  At home we have a dog but the squirrels still get all my nuts (and some of my mason bees, aargh!).

I grew more madrone this spring in case the ones in the ground succumbed to animals, but fortunately that did not happen.  I did kill one due to overwatering I think.  All the seedlings from this spring are spoken for, but if there is interest I could grow more next year since I kind of know what I'm doing now.  IMHO madrones will become more important in this area as the hot dry summers get worse and worse.  I've lost several young big leaf maples, and I have been noticing a dramatic increase in dead alders. Both big leaf maple and madrone are important for mason bees.
