graft cutting

Firstly, I apologize for troubling ascpete.


I tried 'graft cutting'.

The purpose of graft cutting:
In the case of usual 'cutting', rooting and budding take place by the stored energy in the scion. On the other hand, in the case of 'graft cutting', once the combination between the scion and rootstock is formed, rooting and budding take place by the stored energy in the rootstock and scion. When the scion is valuable, short and thin, I thought that 'graft cutting' can raise the success rate than 'cutting'. However, a disadvantage of graf cutting is a mixing of Fig Mosaic Viruses.


Procedure:

1. preparing for scions and rootstocks (1st picture)
Scion:Cucumber, Gino, Narragansett, Pawpaw's Turkey, Seabrook Banana, Smith
Rootstock:Alma, Col de Dame Gris, Longue Daut, Rodos, etc.

I divided each scion into four pieces.
If we assume a success rate of graft cutting is 30%, then the success rate of this case is (1-0.7^4)*100=76%

2. grafting (2nd-6th pictures, performed on Feb. 2-3)

3. brushing indole-3-acetic acid of 0.04% at the bottom part of the rootstocks.

4. planting grafted cuttings (7th-8th pictures, performed on Feb 4)

8_planting_2.JPG 

5. keeping between 60 and 77 degrees fahrenheit.

I want to report the current state of the 'graft cutting' about every 10 days. I hope that all of them will not go south and at least one of them survive.


12 days after planting

All scions are alive now.
(life / total)
1. Cucumber,         4/4
2. Gino,         4/4
3. Narragansett,     4/4
4. Pawpaw's Turkey,     4/4
5. Seabrook Banana,     4/4
6. Smith        4/4

Buds have begun to break through Parafilm.

About 2 or 3 weeks later, scions will start to put forth leaves. If the combination between the scion and rootstock are not completed, the scion dies. What will happen?

Mizuyari,
Thanks for the update.
No apologies necessary, Your original post was filled with information, links and pictures and deserved a Topic of its own... as can also be seen from the updated pictures. Thanks again for starting This topic and posting the updates.

If the scion dies, the rootstock should root and continue to grow.

Looks like a good start. Do you have any idea on root development? Keep us posted on their progress.  Do you keep the trays in a humid chamber?

I do not know whether this experiment succeed or not, but I am going to update until a result is given. I wish that I can offer any useful information.

I will greatly appreciate your guidance.

Rewton

Nice to meet you.

In this setting, I do not know the state of the root. I hope that rooting starts within one month. One month later, I will dig soil and check the root.

I made a chamber which is covered with vinyl. I have not measure the humidity. But I think humidity is high because dew condensation is generated.

Plan on tieing a piece of bamboo or something to support the new growth. I had one like yours that was very beautiful, but as it grew leaves, it became too heavy for the joint to support and it simply broke off when outside. I think it was the wind. your top scions look very good.  it would be helpful if you start thinking how you will secure the top to the bottom without stressing the graft.

You did a fabulous job and I like the way you 'plant' them in the mix,  makes a lot of sense to me. I believe they will survive and will grow nicely.   The joint will need support for a while.

Thanks for your advice. In this graft, combination of the scion and rootstock is weak. I will strengthen the weak point when it starts to grow leaves.

The actual situation is a race against time. Before starting putting forth leaves, connection between the scion and rootstock must be completed and rooting must be started. Otherwise, the scion will dry up. Regardless of a result, I will keep posting.

Thank you for understanding the way the grafted tree is planted. Fig scion is usually planted in this way in Japan.

How important is callousing to the success of the graft? 
For example when grafting grapes; the rootstock and scion are grafted and waxed they are then placed sideways in a cool container covered with a sand mixture for a few months for callous formation. 
After that they can be grown in a greenhouse and field planted the following year.

nice to meet you pino

Thank you for important comment. Callous formation is more important than rooting and budding.

In Japan, for graft cutting for grapes, firstly, callous formation are promoted at around 86 degrees fahrenheit for 10 days. Then cool down to around 77 degrees fahrenheit, rooting and budding are promoted.

According ref. (1), researchers perform graft cutting of fig in March and April, and they plant them in a field. Their success rate is more than 80%. Thus I thought that such measures for grapes are not necessary for figs.

If I fail this time, next time I will control moisture, temperature and brightness to prompt callous formation.

Translation from Japanese into English is welcome. I am not very good at English and I am not familiar with technical terms of botany, so my sentences are probably strange. If there are incomprehensible sentences, please let me know.

(my comment:
They breeded 'とよみつひめ' (= Toyometuhime) as well as 'Kibaru'. They are patented and is not allowed to take outside Fukuoka Prefecture in Japan.

Although there is not fig wasp in Japan, fig breeding has been performed at laboratory in Fukuoka prefecture. Not only capri figs, but also common figs are used as male figs. The following method is patented.

In April, blush or spray gibberellin of 10ppm on breba of common fig.
In July, about 3 stamen per fruit are usually produced in the breba.
Cut stamen out of the fruit, and pollinate it with pistil of main crop of common fig.)

Very interesting. I can't wait to see how they do.

aphahn

Nice to meet you.

I hope that they will survive and become trees.

I am also interested in cold hardy figs. In Japan, Bonholm's Diamond, Hardy Chicago and Quinta are cultivated.

Thank you for taking the time to post all this great info, look foreword to seeing the results.

Good morning Mizuyai,

Very interesting reading your post and I hope to read more..........
Please, would you know what the outcome was for the experiment in the original Paper that was published?
Many thanks

Liza

Luke

Nice to meet you.

I learned a lot from this forum. I hope I can repay my debt of gratitude to forum members.

Liza

Nice to meet you.

I will translate a part of original tables. Please feel free to ask if you have any questions.

とよめつひめ(= Toyometuhime): their developed cultivar
蓬莱柿(=houraisi): imported probably from China in 16th century. Fruit weight is about 100 grams. Brix approaches from 15% in summer to 30% in the late fall.
桝井ドーフィン(=Masui Dauphine): most popular cultivar in Japan

Fascinating information. Thank you  for sharing. I tried using google translation and it showed "when the fried scion"...so I knew it was off! I was confused as to the pictures of the bare rooted plants. Now I see, it was for the experiment so it could be evaluated.  They must have special chambers with controlled temperature as well.

Have you had personal contact with someone doing this? or visited a place?  We all would love to know more about this amazing methods of growing figs. Perhaps one of these are near your city, and you can share more with us about this.

I should have translated the important parts of the paper. As shown in 第一図(=Figure 1) on the page 77,  the length of the rootstock is about 20-25 cm, and all buds (in this case, 3 buds) are cut off. In my case, some buds were cut off, and the others were not. On the other hand, the length of the scion is about 5 cm with one-node. In my case, most of scions were shorter than 5 cm.

'揚げ' means 'rising (or lifting) something from low position to high position' as well as 'frying'. I think more than 99% Japanese regard '揚げ' as 'frying'. Thus '揚げ接ぎ' is very strange Japanese. Since '接ぎ' means 'grafting', '揚げ接ぎ' means 'after digging up rootstock, grafting scion on the rootstock'.

I have no personal contact with the researchers, and have not visited their laboratory. I am not researcher but wannabe farmer. However, they present their research results on this page, so we can learn from there (Sorry, Japanese only)
http://farc.pref.fukuoka.jp/farc/seika/seika07/sei-mo07.htm
They are studying Figs, Kiwi fruits, Grapes, Oranges, Persimmons and Pears. Last year, I asked them whether I could purchase 'Kibaru'. They turned down my request on the ground of law. They are studying fruits for farmers in Fukuoka Prefecture ( I live in Oita Prefecture. )

Thank you for informing me the sites. Step over style is very popular in Japan and efficient. And Aichi Prefecture is Japan's top producer of fresh figs and the head office of Toyota (automaker) is in Aichi.

Interesting variation of step over style is as follows (Sorry, Japanese only)

Very Informative topic.  Thank you for posting this. I may try something similar

Ekierk

Nice to meet you.

I wish you a success. If I fail, please use our data as negative example.

mizuyari, Your work is very neat. I have a question regarding rooting of the rootstock. Would success rates be better if the rootstocks were rooted prior to grafting?

milehighgirl

Nice to meet you.

>Would success rates be better if the rootstocks were rooted prior to grafting?

Yes, it would be. If the rootstocks were already rooted, the success rates would seem to become almost 100%. References are as follows. In my case, I am experimenting on whether graft-cutting goes well. If graft-cutting go well, it would reduce a procedure and time to nurse a grafted tree.

Dear mizuyari,

Two of the links you provided were mine and both grafts are still alive and well!
The fig-fig bark graft is the most interesting to me since both grafts made it. I can take a photo tomorrow as an update. The buds just broke and in a week or two we could see the large O'Rourke leaves. I think the success was partially in a very good and strong rootstock that was rooted fist . It could support the grafts.
The other one, in the duckling post, is still dormant. It has an old leaf but no new ones.

Thank you for your translation and showing us the results of your skills!
