- If you enjoy my videos, subscribe to the channel. It is the only way to be sure you can find more of them. The youtube "recommender" algorithm is not your friend.
** NOTE: This is a tiny sampling of the miracle sisters chestnut trees, the rest being completely free of blight. The video would be much too long if I showed them all.
Watch in 4k.
You're doing Gods work....
Isn't it better to witness a tree with the blight that is fighting it , since the blight will eventually hit all the trees ?
we have a seller here in germany , who offered pure american chestnut seedlings for 5$. The nuts were imported from usa and iwanted to buy 5 for 25$ . They had like 100 in stock . They were in stock for like 1 year but last week they all sold out , i could not get them . SUCH A SHAME
Most likely weren't true Castanea dentata coming from a seller.
Do suckers and root sprouts have any genetic difference from the original tree? I had assumed genetic differences could only come about through sexual reproduction
I thought they were genetically identical
@@matthewhuang9588 Correct except for a very small number of mutations. Unlikely to see it actually happen in person.
In addition, chestnuts do not develop root sprouts, that’s just factually incorrect. They produce sprouts from the stump/collar, but not the roots.
No, they are identical.
I have seen on a different channel some time ago tie a plastic bag of soil against a chestnut with the dirt exposed against the blighted area on the tree. The blight cannot live underground. I believe but can be wrong that the soil neutralizes the acid the fungus puts out to breakdown the bark. My question is can someone experiment with that idea by applying a base solution or baking soda solution to the blight. Therefore thwarting the acid breakdown process of the fungus. Thus starving and killing the blight eventually. I know I am just spitballing but worth a try.
There are most likely bacteria or fungi that live in the soil that can kill the blight and that's what protects the root collar. I remember reading an article on the discovery of antibiotics that said underneath our feet there is an unseen battle of bacteria, fungi and other microorganisms that use sophisticated chemical warfare against each other. They are the source of many beneficial drugs. Fungi secrete enzymes and antibiotics against bacteria. Bacteria secrete antifungals, enzymes, and toxins, against fungi. It explains why wrapping soil on blight lesions can heal them. Trichoderma fungus can attack and eat other fungi in the soil protecting crops in the process. Many plants live in symbiosis with soil organisms, essentially paying for protection with food. It's an avenue that deserves more study.
Root sprouts are not new genetic material. They are clinal tissue, no more unique from the plant than a rooted stem cutting.
