Acer palmatum 'Jinling Huangfeng' is a cultivar that holds yellow color for 160 days during the growing season. The cultivar was discovered ten years ago by Jiangsu Academy of Agricultural Sciences Tourism Agriculture Research Center Nanjing, Jiangsu, China.

'Jinling Huangfeng' is an excellent colorful cultivar selected by Jiangsu Academy of Agriculture, impressing audience by its eternal bright yellow leaves during vigorous growth period. This mutant 'Jinling Huangfeng' showed golden-yellow leaves throughout the whole vigorous growth period and turned orange-red in autumn, providing diversely aesthetic merit. Meanwhile, better adaptability, stronger disease resistance, and less leaf-burning possibility phenomenon guarantee 'Jinling Huangfeng' more commercial advantages than green ones."

I'm guessing that's a Shantung Maple, A. truncatum. Unusual. The JM cultivar looks nice and seems to take sun well, I appreciate learning about it. There are perhaps other yellow cultivars available than those they mention! @AlainK So you think they're doing genetic modification in the lab? Or just regular garden-variety GM, as in garden hybrids?
I was wrong! I read too fast when I saw all those abbreviations. They're studying and reproducing a chance seedling, a mutant to understand better various phenomena like colouring, etc. Er... foot-in-mouth or something as you "Anglos" say ? ^^ Au temps pour moi...
@emery they have other introductions that I didn't include before because I was not sure if anyone would be interested and didn't want to overwhelm my first post with too much information and links.

I think the genetic topic came from one of the links I provided. It's a study that shows genetic changes occur in the leaves of Acer palmatum 'Jinling Huangfeng' when grown in shade. The variety is yellow during summer when in full sun, but if put in shade the leaves turn green (which is something that we all have observed in some varieties). The researchers at the Chinese lab discovered that not only do the leaves change but the genetics change too within the leaves when the tree is grown in shade. This change is also why when we take a shade grown maple that normally stands up in full sun burns when it is moved from shade to sun too quickly. Here is a link to the study that details the specific genetic changes that occur: https://www.hindawi.com/journals/bmri/2015/843470/ This is something I was going to create a dedicated thread, but ran out of time and I also had concerns that general interest may be low among other things. It was this study that lead me to research the variety and discover the information on the Chinese researchers and the other varieties that they discovered. In fact they have written several studies and applied for patent specific to Acer palmatum and tissue propagation, micro-grafting, seed germination, and substrate.
@emery If I were part of The Maple Society I would be reaching out to (if they haven't already): Jinling Huangfeng research team of maple trees led by researcher Li Qianzhong of Jiangsu Academy of Agricultural Sciences. And following their research and patent applications very closely as their research and inventions are both exciting and valuable contributions to maple research! Maybe invite them to a symposium as a guest of honor or as a presenter/speaker. 正宗金陵黄枫--中国金陵黄枫网，金陵黄枫，南京金陵黄枫
It sounds like a great idea, and I will try to see us follow up on it (or do it myself). It is possible we already have contacts there that I don't know about. We're trying to engage as much as possible with China; we were very honored to have Prof Weibang Sun, Director of the Kunming Botanical Garden, as a speaker at the symposium in Roscoff. Thanks!
I'm glad you think so! Maybe less important or off topic, but another idea. It would be great if these events were recorded and posted to YouTube or on the maple society website. Maybe great for education and raising awareness. Might also be good for those members that don't have time, means, or ability to attend a symposium. (Reaching range of: young/old, students/professionals, working/retired or disabled, rich/poor, near/far, ect)
Well, I agree with you there also, and we've had discussions along those lines. But you'd be surprised at the amount of resistance. I think we'll get there some day, but we sure aren't there yet!
