Thank SuperWeed! I wish I kept all the genetic I've work with in the past. I had some of the best genetic from the Super Sativa Seeds Club at the end of the 90th and I wish I had save them... What happened with your SuperMom in 2015?
Cool stuff, how are you wrapping these? is that just saran/plastic wrap?
Here is the final result:

It will rest under the dome for at least 5 day...

Next experiment: Grafting on a potato stem. Why? Why not!

Too far removed genetically?
Mad respect Darpa
Thank SuperWeed,
As you can see in post 96, the potato graft experiment is intended to demonstrate that the taxonomic proximity is a general prerequisite for successful graft-take and long-term survival of the grafted, composite plant. This will illustrate, in a real experiment, the effect of the phylogenetic distance between the potato plant and the cannabis plant on the graft success. (I’ve saw people saying that it was possible on some post) I already know that the result is most likely to be negative, but this is just a way to show it to the community. Nothing is better than pictures!
If you would like me to experiment any other type of grafting technic, let me know! After this grafting demonstration, I will probably be posting step by step pictures for basic tissue culture, callus induction, and if I get my personal lab ready soon enough, protoplasm fusion, cell transformation with agrobacterium bacteria and artificial production of doubled haploids in order to get complete homozygosity in only one generation compared to traditional breeding technique. I’m a curious biochemist that really like to experiment! I have so many project in mind, but it’s mostly to show people what you can do when you dig a little bit deeper. It's all about science!
Tell me you're in Oregon. I need more friends like you Darpa.
This is an awesome thread! Darpa do you mind if I experiment alongside you? I wonder if a side graft would work.
cool projects darpa. i'll definitely be keeping an eye out for your threads.
the project i always had in mind for canna grafting was to graft slow vegging/no stretch wld heirloom scions to vigorous f1 rootstocks in hopes of improving growth rate.
i've often wondered about using a hop root stock with a canna shoot since those vines are so massive and low maintenance, and closely related.
It’s been generally recognized that the success of grafting declines as you move up taxonomic rank (although not necessarily absolute). The success of Species to Species > to Gender > to Family > to Order, etc.
Remember the Simpsons episode where Homer creates the tomacco plant. It’s been done in real life and there were traces of nicotine found in the grafted tomato plants leaves. I guess the question is does nicotine naturally occur in tomato plants. Tobacco and tomatoes are in the same family.
Tomato fruits and leaves naturally contain a low level of nicotine (2.4–6.0µg kg−1). Tomato fruits and leaves naturally contain a low level of nicotine (2.4–6.0µg kg−1). However when you graft a tomato scion on a tobacco rootstock, the level of nicotine found in the fruit is significantly increased. We have to remember that nicotine is synthesized in the root of the Tobacco plant and then transported to the leaves and the lateral parts of the plant, and its quantity depends on the type of tobacco, nitrogen availability, temperature, light, moisture and injury. Fruits of tobacco-grafted tomato cultivars had been found to contain almost a hundred times higher amounts of nicotine than those of selfrooted plant. Interesting fact, beside the increase of Nicotine, research have demonstrate that Tomato-Tobacco grafting resulted to a 30% increase of total fruit weight compare to ungrafted tomato plant!
Grafting tomato plant on tobacco plant and its effect on tomato plant yield and nicotine content, First published: 17 March 2009
Abstract
BACKGROUND: Two different tomato scions, cv. Elazig and cv. Sweet (cherry) (Solanum lycopersicum L.) were self-grafted and grafted onto tobacco root stock (Nicotiana tobacum L.). Then, grafted tomato plants were evaluated in terms of flower and fruit yield. Tobacco-grafted tomato plant fruits were also evaluated for nicotine content.
RESULTS: Tobacco grafting had a positive effect on the tomato plant cultivation performance; the onset of flowering was almost 15 days earlier and the tomato flower and fruit yields increased in both tomato cultivars. Tobacco grafting resulted in 5.0% and 30.1% increase in total fruit weight for cv. Sweet and cv. Elazig, respectively. Because the level of nicotine was within acceptable ranges, tobacco-grafted tomato fruits were considered to be safe for consumption. Self-grafted tomato cultivars also had flowering time onsets almost 11 days earlier. However, self-grafting caused 6.0% and 7.6% less total fruit yield per cv. Sweet and cv. Elazig, respectively.
CONCLUSION: In conclusion, our results show that tomato–tobacco grafting is a novel and promising technique for improvement of not only tomato plant performance and yield, but also that it can be employed to various tomato varieties.
