Growing trees from tissue cultures at North American Plants

North American Plants’ Yongjian Chang talks with Good Fruit Grower about micropropagation techniques at their McMinnville, Oregon facility. When Chang built the company in 1998, they had 800 square feet of lab space to propagate plants through a process known as tissue culture - essentially cloning them to meet nursery demand for ornamental trees and shrubs.
It’s come a long way in the years since, with five expansions bringing lab space to some 23,000 square feet and a switch in 2006 to focus on berries and rootstocks for tree fruit and nuts. Today, North American Plants produces 3 million blueberry, blackberry and raspberry plants and 10 million rootstocks for tree fruit and nuts annually. (TJ Mullinax/Good Fruit Grower)

Great work

Hi Yongjian, Thanks for sharing. It's very easy with all the flasks but how you manage the contaminations issues. I tried several times at home but all flasks are always getting contaminated. Thanks for your help. Daniel

I have been looking for Tissue culture of pines or evergreen likes a Yew or a juniper.

Great job we also work in PTCL

Please can you lead me by giving details in the propagation of araucaria? Thanks

I want to grow the African Shea tree.

[@petermarquardt7803]

Cool. I liked the jars. Where can I buy those?

[@furtherbeyond]

Can any variety of tree in the world be grown from tissue cultures, or are there limitations?

How do I enroll for this

[@simplymaha376]

mind blowing

How do you resolve heating in shelves? Seems you are using florecent lighting, the heat will go to upper levels in shelves...

[@Truth_speaks612]

temperature is maintained 21-25 degree celsius by using AC

I'm not sure about tissue cultured trees at all. I bought tissue culture fruit trees and had problems with them all. They had genetic defects, every third new leaf curled up and was stunted, flowers aborted. This is a problem. Growers who use these methods should keep the trees long enough to see how they perform in soil before they greedily sell them as little nano rooted cuttings wholesale to producers. For me I would prefer a proper cutting grafted on rootstock. It takes years of hard work, often decades looking after fruit trees only to find out they have been genetically damaged in test tubes. Irreparably genetically flawed costing hundreds of thousands in soil amendments, diagnoses, time and energy. What kinds of guarantees can you offer on your root stock?! I'm not surprised you stopped producing fruit trees as such, I am surprised you did so well as a company.
