Can domestic national reserve forest seedlings be grafted

What is the difference between seedling pro-duction and grafting?

The two seedling pro-duction processes are similar but not identical. Producing seedlings to prepare grafted plants borrows a lot from pro-ducing seedlings as standard (non-grafted) transplants. However, specific details about the grafting process de-mand attention before and during seedling production.

How many seedlings do you need for grafting?

For grafting, how-ever, growers and nurseries are encouraged to keep the fol-lowing four major issues in mind. Grafting combines two plants into one. Therefore, two seedlings must be produced for each grafted plant to be used in production.

Can grafting be used in reforestation?

Grafting is used in tree improvement programs to develop seed orchards. Micropropagation or tissue culture has been used for some forest species, but it requires specialized equipment and is therefore not currently practical for most species used in reforestation.

Why is root grafting important in forestry?

There may be advantages for nutrient exchange and for securing trees from wind damage and toppling over. However, root grafting is also an efficient means for pathogens such as fungi to move from tree to tree, and in forestry is undesirable since it contributes to pathogen spread (Külla and Lõhmus, 1999).

Why did ancient trees graft to wild rootstocks?

To multiply desirable varieties, scions of the best trees were grafted to wild rootstocks. For other species such as grapes, the purpose of ancient grafting is less clear since grapes can be propagated from cuttings.

Should rootstock seedlings be irrigated before grafting?

However, currently, experi-enced growers often reduce or withhold irriga-tion and fertigation, especially of rootstock seedlings, for 1-2 days before grafting. This step helps reduce root pressure, allowing firm-er contact at the rootstock-scion interface.
