Yo Yo Yo Check out the NY Oaks wit' Street Cred

Re: Yo Yo Yo Check out the NY Oaks wit\' Street Cred

Sounds like a potential nightmare like the hybrid Black populars we have in the UK that grow 6 feet plus a year,i would never plant one of them pops as a street tree!

What two species are being crossed? Can't tell from the picture.

I planted out 6 viginiana/muhlenbergii crosses 8 years ago. They looked good early; I should check them again.

Neat web site Bustus. Lots of good science news.

It looks like traditional tree breeding is being used to come up with the desired cultivar and then maybe plant tissue culture to multiply the desired tree to high numbers. The article does not get into the 'how' of rooting the clones but I suspect it's done in test tubes.

One problem with clones is the narrow genetic base. If a city has thousands of trees with the exact same genetics(clones) and an insect or disease comes along to which this cultivar is susceptible every specimen would likely be affected. This is a serious drawback of monoculture and one that is not likely to be easily overcome.

Genetically engineered trees will also need to be multiplied by rooting cuttings or plant tissue culture. It will be interesting to see the publics acceptance of GM trees and the repercussion that result as they interbreed with the native tree population. For instance the Bt in GM corn if put in trees would kill gypsy moth feeding on those trees but the Bt modification would spread into the native trees.

How old is such breed and how are the rooting qualities over the long term? I know some nice elm selections are wrecked after 30 years or so as the roots didnt follow the crafted upper tree. I dare to say that with trees you need to grow them first for decades (at targeted location instead of at a nursery) before you can be sure the species is fit for the trade. I think or believe that growing those hybrids for 6 years cant show how they would devellop into old trees. You might get unwanted crotches, wide span crown, maybe after 30-40 years decline of the tree from grown 'wanted' specs back to his 'roots' (trees originally selected from).

I think it's great news, what could take eons for evolution to achieve can be made in years.

Plant growers, dog breeders etc have for some time been trying to manipulate via selective processes to get purity or features that are specific for a task.

Over here plant growers that "invent" a species get PBR (plant breeders rights)notation and all royalty goes to the PBR holder. Propogation and duplication without licence is an offence.

I think if the trees are going to be better off it's good news.

Yes there's a whole bunch of unknowns for 30 years down the track but hey ... nothing ventured nothing gained. They're going to trial them anyway.

I know that a few plants here have been modified somehow so that they have sterile seeds. This then allows them to be used freely coz they cant become invasive.

Yeah Eric we have plant patents too.

Ron and Dan are right but we don't have decades to wait imo so plating out small blocks now makes sense. No large monocultures--can anyone say "Marshall's Seedless Ash"?
 
Re: Yo Yo Yo Check out the NY Oaks wit\' Street Cr

ok but you dont have to deal with the t 22 highbrid black pops or maybe some clone of a ray woods ash that planted in an avenue in the slightess bit off wind every time 80% of the treess snap out due to they are all clones and share the same weakness,more reasearch please! other wise just like the highbrid pops the only way of containing there growth, as they grow six ft a year is pollarding and we dont wanna do that do we!

Frans,

As much i love trees i just dont like to implement trees that havent proven themselves. I know they need a fair start to see how they develop etc. I just think these days its more a 'sales' point saying "we have selected the best qualities from very different species and made us a wonder tree to use in city conditions". There no such thing as fixing up a tree to all demands. I rather would see a good thoughd over planting method were trees are imbedded on (protected) locations were they can develop for centuries. And i mean the tree species we already have for ages. Thats our heritage we should take care of. Within a city plan were areas are pointed out for trees to grow as they want i still believe that new grown species have a place. Make some good locations in sight, crossings, parks, main roadways etc were trees can come to full growth and use specific grown trees there were space is less.

Yeah; woe betide the farmer who gets more than one year's service out of his seed over here!

Don't know about that plant but it sounds like it was met with the same sort of fate as perhaps the currently-largest and severely blighted monoculture known by the name "Windows", for which an entire side-industry has sprung up to only marginally feign protection!

Haha Glens, you had to stick it to Gates hey, you make me laugh. /forum/images/graemlins/laugh.gif
 
Re: Yo Yo Yo Check out the NY Oaks wit\' Street Cr

I thought I'd read that they were sterile, but I can't see it in this article, which looks like the other I've seen. I can't tell if they hybridized two or more species. It says 200 combinations were started, where did the end result come from? What I also didn't get is that at first they're talking about developing new cloning techniques to improve "rootability" and then they switch to talking about cold- and drought- tolerance as the attributes. I guess they're tring to get it all. We'll see.
I found this also, not much else there: http://www.news.cornell.edu/stories/June06/oak.maple.cities.kd.html
