I visited Dr. Campbells house in July and he is working with 3 different dwarfing rootstocks. Piva was the main one but there was also a dwarfing rootstock from Costa Rica. I wish I remembered more. I do remember him stating that one of his rootstocks dwarfed Asian varieties but not Indian varieties. I will have to contact him for more info. Very interesting video. Thanks!
This is an interesting video. Thanks heaps! Here in Australia the mango industry is working with the government primary industries department to trial a range of dwarfing rootstocks. They have found that dwarfing rootstocks are not compatible with every variety. They are trying to match the best rootstock for each scion variety. They found big increases in production with a good match and often no production with a poor match. Most of the rootstocks studies are polyembyronic so the effects should be fairly consistent and they should be able to ramp up production fairly rapidly once they have matched the rootstocks to suitable varieties. What I found interesting is the popular KP variety has performed well on a number of rootstocks, while some new varieties that are the direct offspring of KP, performed poorly on the same rootstocks. It's clearly going to take some years before they work out the best match for each variety. I hope there a Chapter 2 for this video at some stage. Thanks again!
very usefull information, i have a couple of root stock thats looking like dwarf,,, i also haVE A CARRIE planted in the ground and it was grafted on a dwarf rootstock,, she is sooo beautiful
Good video, I actually just successfully gafted a Keitt Scion to a Neelum seedling. Its looking healthy so far, gonna wait for it to get a little bigger before I plant it.
I think it's important to clarify the difference between, low vigor, and dwarfing. ideally a true dwarf, would be a tree, that reaches fruit production maturity as any normal tree. and is just as productive for its size as any normal tree. but trees that are small because they are just extremely slow growing, and take a decade to produce fruit at low productivity, is just not the same thing. what you have in these circumstances is basically a bonsai, all that is happening is that something is restricting the growth, whether it's a major incompatibility issue. between root stock and scion. or their is some restriction of nutrients between the two. A lot of research needs to be done with this, and it wont be easy. to find a root stock that not only is well adapted to local soils, but also has a true dwarfing trait on the variety of mango you want to grow. there are literally thousands of combinations. will a particular root stock truly make your tree a dwarf, or will it just make it a stunted runt ?
Interesting concept Chris - I was under the initial understanding that grafting quite high up had a dwarfing effect than down low but that last plant disproved that idea? Maybe as you said an incompatibility issue but the plant doesnt die like other Species would like Sapodillas?
I could perhaps find an answer to my query on the net, but I'm sure you will be able to answer my question to my satisfaction. I recently saw in a local market an imported Kent variety mango from Mexico. I had never seen a Kent variety before. I bought it and after trying it, was not overly impressed, however, it wasn't the worst mango I've tried. I decided to grow the seed, being monoembryonic, I'm wondering what the resulting fruit would be like from this Kent seedling. And if I had several Kent seedlings would each plant produce different tasting mangoes or would all the fruit from the seedlings look identical and be identical in flavour. Thank you for your assistance.
i am also interested in dwarfing root-stock so i bought different dwarfing trees ice cream, honey kiss, dwarf Hawaiian & some others. my idea is to air layer off some branches to use as dwarfing root stock. i'm guessing the south pacific types will be compatible with Nam Doc Mai#4 & the Indian types with honey kiss or dwarf Hawaiian.
