Satsuki Azalea - Genetics explained by Dr Pettersson
ฝัง
- เผยแพร่เมื่อ 28 ส.ค. 2024
- In this video I have an enlightening conversation with Dr Olga Petterson from Sweden, about the Satsuki Azalea and why the flowers have the colour displays they have, how to prune and what conditions they like to grow in.
Did you know there are jumping genes?

My first lecture ever delivered in washed-out trainers, with broken and dirty nails, no make-up and the sun straight into my eyes ;))) But it was all genuine and right next to the subject!
Thank you for giving me this opportunity to share some of the knowledge with your fans, Peter!
The fans love your lecture.
It was a pleasure listening to you, Olga - Thank you very much!
Tack för att du delar med dig om fakta kring Satsuki azalea och Rhododendron! 😊 Jag har länge undrat över hur Satsukin särskiljer sig från de azaleor jag brukar se i affärer. Det var jätteroligt att se en annan svensk på en av mina favoritkanaler. 🥰❤ Hoppas du har en trevlig fortsättning på din sommar! ^v^
@@alva7040 Men gu vad roligt! Tack själv :) Ha en trevlig sommar du med!
Good morning Sunday breakfast club
Morning 😀🌳☕️🥐
Wow..know I know more about Azaleas..thx for sharing Peter 👍. Can't wait for more...
I have been waiting for this episode for years now. Thank you Olga and Peter for explaining what's the difference between the satsuki and the normal azalea. Indicum vs simsi and japonicum azalea. THANK YOU!
Another awesome educational and enjoyable post, thank you.
🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹 thanks Peter
I love the effort Mr Chan goes to, even his shirt matches the doctors tattoo 🙂
Puhhhlease... Doctors match their tattoos to Peter's shirts!
@@3apa3a4eva Haha, didn't realise how inspirational his shirts were. Well done on the video, some really interesting information
@@3apa3a4eva 😂 Thank you! That only supports my theory that there are no actual cascades in this nursery - just ordinary trees bowing to Peter.
I really loved it that Olga went into the science of satsuki :) It was pleasant to watch you two together!
Really enjoyable conversation between the two of you. Great knowledge this lovely lady has about rododendron/azalea’s. Thank you all for the fun and interesting content!
What a great video. And such beautiful variation in the flowers. Good to see Peter in his fancy shirt looking smart! Happy day!
How wonderful is nature? Outstanding beauty.
Very good information
You are looking great Mr. Chan in this hot 2022 summer!!
Outstanding.
Very, very interesting video. I wish we'll get the chance to hear Dr. Pettersson discussing about other species popular for bonsai such as junipers, pines and japanese maples.
What information would be useful fo you to know? I am sometimes thinking to write up some of the "bonsai science" things one day.
A great request.
@@3apa3a4eva I think it is a fantastic idea! It would be great to have someone with a background in botany, plant genetics and physiology explain the science behind manipulating trees, miniaturising and shaping them into bonsai. Even some video explainers (vlog style like Peter does) would be great. I can think at so so many bonsai topics I would love to hear the science behind, such as: plant hormones and techniques to tweak them for specific results; back-budding in various species; budding on nodes/internodes; foliage reduction/needle shortening; foliage density (juniper); types of juniper foliage (scale/needles); layering (air or ground in various species); trunk/major chops on trees etc. Or maybe addressing some of the things most heard/debated among bonsai practitioners such as "strength of juniper is in foliage", "cedar don't like the roots touched", "conifers roots need a lot of oxygen". :)
Could you please make video about how to make Satsuki azalea bonsai?
Very informative.
Hello thank you for this video really interesting from Guatemala
Heron Bosnia should collaborate with Matt Powers and Dr. Pettersson
A beautiful Sunday morning to you all Breakfast Clubbers! This one is going to be great!
Edit: Thank you Dr Pettersson, a fascinating insight. Maybe Peter should do some more experiments and collate his results!
Good morning!
Thank you!
so interesting , thank you both,
That was very informative I learnt a lot from. Thank you Peter and Dr for sharing
Beautiful bonsai my favourite 😍
Beautiful trees ❤️
Thanks for the knowledge you share !!!
Such wealth of information from the very educated lady.
Fascinating episode. The scientific background is very interesting. Thank you for this deep dive into satsukis.
Great information about Azeala there.Well done Dr Peterrson
Thank you for this discussion and for bringing in Dr. Pettersson. Part of the reason I fell in love with plants and trying to do Bonsai was my interest in science. This was fascinating to me!
I so enjoy seeing Peter delightfully stumped on the alchemy of genetic mutations and environmental conditions that Dr. Petterson explains, combine to influence the color of Satsuki azalea flowers branch to branch on the same tree.
This was a really great talk through concerning Satsuki Azalea from Dr Petterson 🙏
Deepfull subject...
💕🔥👍
Very well explained and entertaining video. Love it
Very interesting to know about biology and genetics of rodhodendron
🌹🏵💮🌸💐🌺🌻🌼🌷🌱🌲🌳🍁🍀🌿🌾wow ..
So smart 😇the explanation is until genetik level.This is deepening that needs to be understood more for all bonsai lover/bonsai maker😇
More please!!
Thank you Peter and Dr. Pettersson. I was given a Satsuki Azalea (Azalea 'Shiryu-no-Homare') a year ago. Your discussion was really helpful. Now I understand why it bloomed so heavily in the hot spot I put it without thinking. This Azalea LIKES heat!
This was very interesting. Thanks to you both!
Thank you Peter and Angela - that was fascinating!! One question about air layering and cuttings - Angela mentioned the need the roots have for mycelium - do we need to add specific mycelium to cuttings and air layers to get health roots?
No, you do not have to. Azalea cuttings will have their own mycorrhizal mycelium already present in the branch tissues.
6:20 No. red does not go to pink. Red stays red. But pink with stripes can become pink without stripes, stay the same, or become entirely red. It is a one way street. white -> white with pink stripes -> pink -> pink with red stripes -> red. How many stripes you get depends on probability and maybe on the conditions while the flower buds grow and form. The stripes you see in the flower also occur in all other tissues. You can see stripes in the leaves as well during autumn, when chlorophyll breaks down. If a branch contains a red striped tissue, and new side-branch grows from exactly that red tissue, the entire branch will have red flowers only.
If you propagate from that pink-with-red stripes branch, you may get entirely pink flowers. Or you may get the pink with the red stripes. And if the plant gets larger, you may get an entirely solid-red branch on there as well. So you propagate from lightest coloured branches. Preferably white. If you propagate that Issho no Haru 2:33, you propagate from the off-white flowered branches. If you get a branch with a jewel border/fukurin flower, or entirely purple flower, you will never get the very pale flowers with the pink stripes or sectors. If you propagate from a white flower with stripes, you may get entirely white flowers because the conditions during flower bud formation as well as the luck factor don't generate any stripes for that year. But eventually you will get stripes.
No...
@@marcusaurelius1477 Yes
I only have one multi color azalea japonica and that is a small one so it is eazy for me to see the flowers on the branch change from year to year and you can not plan the same color on it from year to year but i dont have a real satsuki
Tack Anders! Misstänkte väl det.
Hi, when's the best time to take cuttings from Azalea species?
When the young wood has hardened somewhat. Check out Peter's videos on maple propagation by cuttings, it is the same principle.
Right now.
Can you do a video on can any tree be a bonsai please
I was also thinking this😮😊
I still don’t see Azalea as a tree.
I respect your opinion .
It is not a tree, it is a shrub ;)
@ biski In that case do u consider a boxwood to be a tree? Cause its not but is still turned into a bonsai. I guess u can say a boxwood isnt a tree also. Anything can be a bonsai.
@@Chris-oq6kn well I have my opinion and a shrub should not be a miniature tree because it’s not a tree on nature . Sorry I don’t see your example as a tree neither.
@@3apa3a4eva in this images is representing a miniature tree or bonsai. Since that form doesn’t represent Azalea in nature to me it’s not a bonsai. Are we allowed to have our own opinion? It’s the part of Bonsai that I am disagree.
@@mariapilarme Oh, I get you now! Right, I am not a big fan of styling everything like a pine either.
The attraction of Satsuki’s is the surprise you get every year! It would be a shame to develop mono-coloured plants!
Wow
If we were to look for scientific papers on azadendrons, what would be the correct search terms for good hits?
I am still baffled that genes and coding mechanisms roughly can place arms and legs on a fetus correctly and that a low number of amino acids can create such diverse designs.
The cool thing about the pigmentation here is that there are so many variables, from genes, enzymes in the environment to different solar radiation effecting the flowers. These properties seems to have either been bred out of other species, streamlining their gene pools, or not have been present in the initial gene pool to begin with.
Having looked into old swedish farming books, our single stem wheat and oats was once multistemmed, but were heavily selected into their present state.
Hybrids of (evergreen or deciduous) azaleas and true rhododendrons are called 'azaleodendron'. Not sure if there are many papers on that subject.
Really nice interview! Question though: "All Satsuki's are Rhodondenron Indicum", but are all Rhodondendron Indicum also Satsauki, or is that not necessarily the case?
There are many cultivars in the Indicum cultivar group, including the Satsuki azaleas.
Satsuki azalea is a cultivar group of the species Rhododendron indicum, a type of azalea extensively cultivated by the Japanese. It is native to the mountains of Japan.

@@3apa3a4eva greetings from Estonia and thank you Dr. Pettersson for sharing your knowledge!
@@aivarpetrov7447 Tere! I am Latvian originally :))
@@3apa3a4eva good to see fellow neighbours interested in bonsai. Not so much here in East/North Europe :)
Never mind the flowers, I think the trees are at their best when bare.
Quanto custa uma árvore destas , azaléia?
👍👌🍎🙂
You can tell from Peter's face that he is not happy with some of these mysterious answers. I've never seen him confused about his own plants before.
I was very nervous... ;)
@@3apa3a4eva Nothing against you, just that he's not happy not knowing something.
The wonders of nature leaves me in awe.
I have an azalea that I have had since 2000... some pink flowers and some red... I was told it was indeed due to mycrorhizomes in the soil and the acidity of the soil🙃👍🏾❤️✊🏾
Can Satsukis grow in the tropics?
Possibly. You can grow vireya and a vireya x satsuki crossbreed seems possible. It was possible for Vireya x Belgian indica.
Thank you!
Great video and knowledge. I tell everyone to buy the book floral treasures of japan by alexander kennedy if they want a good book to read and go in depth. It helped me alot.
Beautiful colour. How long its blooms?
Glad she didn't take a bunch if trees out at tye beginning
Tradução Pará o português do Brasil GRATIDÃO 🙏👏
You guys got really somber talking about the one that doesn't like to get hot. Many hmmmmms
🌳Another great video Pete ! Shame about the inconvenient airplane ✈ pilot's! 😉👍
It could be possible that there are mutations inside of the stem-cells of the azaleas.
There are stem cells on every apex (called meristems). Their daughter cells grow out to branches, leafs or flowers etc.
So if the stem cell of a flower has a mutation in a gene that's responsible for the color, the flower could change the color.
But the stem cells can not divide infinite and will be replaced after time. The new stem cell could be without the mutation and 'regenerate' the old color of the flower.
That could be another explaination why there are different flower colors on a single tree, but i'm not a doctor 😂
I think it is a plausible variable to be accounted for as well. But gosh there are so many of them... :)
Yes, the stripes follow the growing pattern/cell divisions. As you move outward towards the flower cells, there are more daughter cells of the original cell that mutated ie had the transposon jump.
