What does it mean that apples don't "come true" from seeds? What is grafting, and when was it first practiced? Explain why, "if not for grafting, every apple in the world would be its own distinct variety." How many new apple varieties could come from each tree?

Respuesta :

Grafting has been used for centuries to propagate fruit trees. Grafting allows us to maintain and prolong the lifespan of valuable fruiting trees for growers. Most apples require cross-pollination in order to bear fruit.

What is grafting?

Grafting, also renowned as graftage, is a horticultural technique in which plant tissues are joined to proceed their growth together.

Most fruit trees do not grow true to seed because they have not been inbred sufficiently.

However, some plants, such as apricots, nectarines, peaches, and avocados, grow nearly true to type, producing fruit that is similar to the parent plant. Furthermore, some citrus fruits and mangos are polyembryonic.

Grafting has been used to perpetuate fruit trees for centuries. Grafting enables us to keep and extend the life of valuable fruiting trees for growers. Cross-pollination is required for most apples to bear fruit.

Thus, apple seeds are not true seeds.
