What is grafting, and what are the key principles involved in this technique?

• Combining two different plant parts into one.

• Growing plants from seeds

• Cloning plants through tissue culture.

• Propagating plants through root division.

What are the main purposes of grafting in plant propagation?

• To grow plants faster.

• To change the color of flowers.

• To combine desirable characteristics of plants

• To make plants taller.

What is a graft union, and how is it formed?

• The point where the scion and rootstock join and heal together.

• The process of planting seeds.

• The method of pruning branches.

• The technique of watering plants regularly.

What are the steps involved in the formation of a graft union?

• Planting, watering, pruning, and harvesting.

• Cutting, aligning, securing, and healing.

• Fertilizing, irrigating, mulching, and weeding.

• Seeding, germinating, transplanting, and growing.

What is graft compatibility, and why is it important in plant propagation?

• The ability of two plants to grow together successfully.

• The ability of plants to resist diseases

• The method of growing plants without soil.

• The process of producing fruits.

What are the causes of graft incompatibility, and how can it be overcome?

• Soil pH levels and watering frequency.

• Genetic differences and biochemical reactions.

• Sunlight exposure and temperature.

• Fertilizer type and application method.

What are the symptoms of graft failure, and how can they be identified?

• Healthy growth and blooming.

• Poor growth, discoloration, and swelling at the graft union.

• Increased fruit production.

• Rapid growth and flowering.

What is localized incompatibility, and how can it be overcome?

• Occurs at the graft union, overcome by using interstocks.

• Involves the entire plant, overcome by regular pruning.

• Affects the roots, overcome by adding fertilizers.

• Affects the leaves, overcome by spraying pesticides.

What is translocated incompatibility, and how can it be overcome?

• Local structural issues, overcome by grafting at different angles.

• Systemic biochemical issues, overcome by using compatible interstocks.

• Root absorption problems, overcome by changing soil type.

• Leaf exposure problems, overcome by altering light conditions.

What are the two types of graft incompatibility, and how do they differ?

• Root and leaf incompatibility.

• Localized and translocated incompatibility.

• Stem and flower incompatibility.

• Soil and air incompatibility.
