Question

Which of the following action makes a seed coat becomes permeable to water?

• A. Scarification
• B. Stratification
• C. Vernalization
• D. All of the above

Answer 1

The correct option is A Scarification

Scarification involves weakening, opening or altering the coat of a seed to encourage the germination. It can be done mechanically, thermally and chemically. This will make the seed coat permeable for water and air, which will help in germination of seeds.

Stratification is the process of pretreating the seed to stimulate natural condition that a seed must endure before germination. It involves soaking and chilling of seeds prior to sowing.

Vernalisation is the induction of plant's flowering process by exposure to the prolonged cold of winter. It literally has to be chilled in order to reproduce.

Somewhere, all these processes are used to break the dormancy the seeds naturally as well as artificially

So, the correct answer is 'Scarification'
