Pollination

Question 1

What is meant by the term compatibility

Answer 1

Plants which can cross pollinate with one another

Question 2

What is meant by the term incompatibility

Answer 2

Plants that can’t cross pollinate with one another.

Question 3

What is meant by the term diploid

Answer 3

A diploid has one set ofchromosones from male parent, and one set from the female parent. They can produce fertile ovules and pollen.

Question 4

What is meant by the term triploid

Answer 4

They produce viable ovules but do not produce viable pollen.

Question 5

Why is cross pollination and fertilisation important in top fruit?

Answer 5

Apples, pears, some plums and some cherries are self-infertile, and so must be cross pollinated to set fruit. It also allows new genes to be introduced.

Question 6

Why are pollination groups in apples important?

Answer 6

groups must flower at the same time in order for them to cross pollinate and set fruit.

Question 7

What is an example of a diploid cultivar?

Answer 7

Apple ‘Granny Smith’

Question 8

What is an example of a triploid cultivar?

Answer 8

Apple ‘Bramley’s Seedling’

Question 9

What is an example of a self-fertile cultivar?

Answer 9

Plum ‘Stanley’

Question 10

What is a self fertile cultivar?

Answer 10

A plant which can pollinate itself.

Question 11

State 4 methods of ensuring effecting pollination in fruit production

Answer 11

Cultivar selection
Planting extra pollinators such as crab apple
Shelter belts and hedges to encourage pollinators and provide windbreaks
Have pollinators within 3m of each other.
Put bee hives in the garden.
Warmer, sheltered sites provide higher temperatures at time of pollination, which allows from more effective pollination.
