Good morning, I would like to know if you can graft plum scions on a fig tree, thank you
Fig grafts: Answer: grafts
grafting is a practice widely used in horticulture, above all because most of the fruit plants on the market are hybrid plants, and moreover they are plants resulting from various crosses occurred over the centuries; for this reason, if we sow the seeds, it is very unlikely to obtain plants with fruits identical to those of the mother plant. In addition to this, the practice of grafting allows us to donate to the plant to be grafted some cultural characteristics of the rootstock plant, such as greater resistance to drought for example, or greater resistance to frost.
For this reason there are different rootstocks for the different climatic zones present in Italy, in this way we can cultivate the same variety of apricot in Milan and Naples, obtaining the same identical fruit (more or less).
How does the graft work?
We take shoots or branches from the plant that we intend to propagate and graft onto a plant called rootstock; between the two plants it is important that there is a certain genetic similarity, otherwise the rootstock will recognize the plant on them grafted as a foreign body and will not allow rooting of the grafted branch.
Most of the cultivated fruit plants are rosaceae, and therefore have ancient common ancestors, with a certain similarity at the level of the DNA; despite this the fruit plants are cultivated and hybridized for centuries, and therefore their degree of kinship has been diluted over time.
For this reason, grafts on fruit plants of different kinds do not always occur successfully; we can for example graft nectarines on an apricot tree, but hardly able to graft a pear on a plum tree.
The grafting of the most common fruit plants on a fig is then impossible, since these are plants that have no degree of kinship, since the fig tree (ficus carica) is a plant belonging to the family of moraceae, while the pear tree (pyrus communis) belongs to the Rosaceae family.
If you want, you can graft your fig with one of the dozens of varieties of figs in cultivation in Italy, being able to obtain a fig tree that produces, for example, both green figs and black figs; then there are truths of figs that are more or less early or late ripening, with the graft you can therefore obtain a much longer fruiting period, making several branches bear fruit to climb.
Pear tree scions can be grafted onto a quince, which tends to be more resistant to disease, and more vigorously developed.
