Question

______ layering, accomplished in springtime, is very similar to simple layering except that a stem is covered by soil at two or more points along its length.

a. flat

b. compound

c. stool

d. trench

Explanation:

To solve this, we recall plant propagation methods. Compound layering involves covering a stem with soil at two or more points (unlike simple layering with one point), done in spring. Flat layering has a stem laid flat, stool layering uses a stooled plant, trench layering uses a trench. So the correct term is Compound.

Answer:

b. Compound
