Layering

3

What is layering in artificial propagation?

Inducing roots while the plant is still attached to the parent

4

Grafting combines which parts of plants?

a

Scion and rootstock

Seeds and pollen

c

Leaves and stems

5

Micropropagation is carried out in which environment?

a

Hybrid

b

Explants

c

Mutants

7

What is a major advantage of vegetative propagation?

a

Higher genetic diversity

b

Increased vulnerability to pests

c

Genetic uniformity among offspring

8

Which crop is classically propagated vegetatively?

a

Wheat seeds

b

Rice grains

c

Potato tubers or slips

9

What is a potential disadvantage of artificial vegetative propagation?

a

Need for many pollinators

b

Requirement of seeds for each plant

c

Spread of diseases through clonal material

10

In this process, a part of stem is cut or removed from the mother plants and then planted into soil or water to become a new plant.

a

Stem Cutting

b

Budding

c

Grafting

11

A propagation technique in which a bud from a healthy and desirable plant is removed and transferred to the stem of another plant.

a

Stem Cutting

b

Grafting

c

Budding

12

What is ground layering (layering) in plant propagation?

a

A stem is bent to form a new plant while still attached, with roots developing at the buried section.

b

A seed is planted in soil and grows independently.

c

A plant is grafted onto a different rootstock

13

What advantage does grafting typically offer?

a

Makes plants grow without water.

b

Increases plant height rapidly.

c

Combines desired traits of scion and rootstock for improved vigor or fruiting.

14

Define marcotting (air layering).

a

A branch is wounded and wrapped with moist medium to root while still on the parent tree.

b

A cutting is planted in sterile soil to root.

c

A seed is eaten by insects to trigger growth.

15

Which tool is commonly used for grafting cuts?

a

Grafting knife (or bud knife)

b

Shovel

c

Pruning shears

16

In ground layering, where should the buried stem portion be kept?

a

On the sunny branch tip

b

Just below the soil surface and kept moist

c

Completely underground

17

What best describes a grafted plant?

a

Rootstock and scion from compatible varieties joined to grow as one plant

b

Two separate plants grown side by side

c

A plant grown from a seed only

18

What is the main goal of marcotting?

a

To prune the tree to stop flowering

b

To form a rooted shoot while it remains attached to the parent plant

c

To create seeds from a mature tree

19

Which grafting method uses a T-bar or tongue cut to join scion and rootstock?

a

T-budding or cleft grafting (commonly used)

b

Layering graft

c

Seed grafting

20

Which condition favors successful grafting?

a

Careful alignment of cambium layers and proper sealing to prevent drying

b

Planting in very dry soil only

c

Using roots from a different species

21

How does layering differ from marcotting?

a

Layering roots while still attached; marcotting creates roots on a detached branch on the parent tree

b

Layering uses seeds; marcotting uses cuttings

c

Layering is only for annuals; marcotting for perennials
